### 1. Conclusion and termination of the contract

#### 1.1. Conclusion of contract

1.1.1. The contract for the use of sipgate services is concluded when sipgate accepts the customer's order for the provision of the services. Acceptance shall be deemed declared by sipgate ten calendar days after receipt of the customer's order, provided that the sipgate connection and the sipgate account have been activated and enabled by that time. The customer is bound to their application for 5 working days.

1.1.2. Details regarding the term of the contract are governed primarily by the sipgate service description. Unless otherwise specified there, the contract has no minimum term.

#### 1.2. Ordinary termination

1.2.1. Details regarding the notice period are governed primarily by the sipgate service description. Unless otherwise specified there, the contract may be terminated by either party with one calendar day's notice to the end of the month.

1.2.2. Terminations must be made by email or in writing (letter or fax).

#### 1.3. Extraordinary termination

1.3.1. sipgate reserves the right to extraordinary termination for good cause. Good cause exists in particular if the customer culpably breaches their obligations under the contractual relationship and it cannot reasonably be expected of sipgate to wait for the expiry of the notice period. Such a case exists, among others, if the customer:

* opens a sipgate account under a false name or false identity and/or
* uses the sipgate account, the connection or the phone number assigned to them in an abusive manner and/or
* insolvency proceedings are opened against the customer's assets or the customer files an application to open insolvency proceedings and/or
* direct debits are reversed after being charged.

1.3.2. In addition, sipgate has the right to extraordinary termination in the event of changes to the legal basis of this contract, or orders and/or directives relating to the contract by authorities, courts or other bodies exercising public authority, provided that these result in it being unreasonable for sipgate to continue the contract.

1.3.3. The customer's statutory right to extraordinary termination for good cause remains unaffected.

#### 1.4. sipgate credit balance upon termination of the contract

1.4.1. If, at the time the termination becomes effective, the customer has a credit balance on their sipgate account, sipgate undertakes to refund this to the customer upon corresponding request. The customer can make the request via their sipgate account. . The refund by sipgate shall be made by way of a credit to the customer's specified bank or credit card account.

1.4.2. Any other refund of sipgate credit is excluded.

#### 1.5. Inactive accounts

If the customer has a sipgate account that they have not used for more than one year (inactive account), sipgate is entitled to delete the sipgate account. sipgate will first inform the customer of the intended deletion via the email address stored in the sipgate account. If the customer does not object within 4 weeks, sipgate will delete the customer's sipgate account.

### 2. Customer's obligations to cooperate

2.1. The customer is responsible for maintaining an internet access suitable for use with sipgate (see requirements for use – internet access). If this is not the case, the mutual obligations to perform under the contractual relationship remain unaffected.

2.2. The customer must take all necessary and customary security measures against unintended and abusive use of their sipgate connection by third parties. If the customer detects unintended or abusive use, they must inform sipgate without delay.

2.3. sipgate handles essential communication processes (including those relevant to the contract) via email. The customer undertakes to provide their own valid email address when registering with sipgate and to check it regularly, as well as to inform sipgate immediately of any changes to their email address.

2.4. If there are any changes affecting the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed immediately. This duty to report applies in particular to the following points:

* Change of the customer's residential/business address (among other things necessary for the correct location of emergency calls). Further information at: [Instructions for making emergency calls](http://www.sipgate.de/team/nutzungsbedingungen#emergency_call)
* Change of the customer's email address
* for payments using the autopup method, the bank details and credit card information.

2.5. The customer may use the connections to sipgate only as intended and in accordance with the (telecommunications) laws and regulations in their applicable version. The customer is obligated not to misuse the telecommunications services offered by sipgate for purposes that conflict with statutory provisions, the relevant [sipgate service description](https://www.sipgate.de/leistungsbeschreibung) or the sipgate T\&Cs.

2.6. The customer undertakes not to use any equipment or run any applications that may lead to changes in the physical or logical structure of the network provided by sipgate.

2.7. The customer undertakes to keep access data for their sipgate account and user accounts as well as access data for sipgate's VoIP service (user password or SIP ID and SIP password) confidential and secure and not disclose them to third parties. If the customer has legitimately disclosed access data to third parties (e.g. their employees), they must inform them of the obligation to keep the access data confidential and secure and require them accordingly.

Private customers on tariffs with multiple users (upgrade to business S, L, XL) may only pass on the contractual services to persons in their own household.

2.8. The customer agrees that their phone number may, if applicable, be transferred to a network operator other than the one used at the time the contract was concluded. This entails no costs or disadvantages for the customer; the contract between sipgate and the customer remains unaffected.

2.9. sipgate is entitled to change the customer's phone numbers,

* if the customer agrees to the change,
* if this is required due to legal regulations or official measures (in particular the Telecommunications Numbering Ordinance or decisions of the Federal Network Agency),
* or if there are corresponding economic or legal constraints that sipgate cannot otherwise resolve with reasonable effort.

2.10. The customer is not permitted to pass on sipgate services provided to them to third parties in a commercial manner without sipgate's consent.

2.11. If the customer or a user authorized by them engages in abuse (e.g. violations of 2.5, 2.6, 2.10 or comparable breaches) and the customer does not cease the abuse within a reasonable period after being requested to do so by sipgate, sipgate is entitled to block the customer's sipgate connection or – where applicable – delete user accounts created by the customer. If the customer is responsible for the blocking or deletion, sipgate will charge the customer the costs of the blocking/deletion. The customer is obligated to pay the base fees incurred during a blocking period if they are responsible for the blocking.

### 3. Connection charges

3.1. The customer is obligated to pay for any use of their connection for which they are responsible.

3.2. The customer is also obligated to pay the charges caused by the user or co-user. This also applies in the case of abusive use, unless they prove that they are not responsible for any breach of duty.

3.3. The obligation to pay remuneration does not apply where facts justify the assumption that third parties have influenced the charged connection fees through unauthorized changes to public telecommunications networks.

3.4. The fees for the VoIP service result from the price list applicable at the start of each individual connection for the product selected by the customer according to the sipgate service description. The current price list can be viewed online at any time via the respective current link.

### 4. Billing and payment

#### 4.1. Billing methods

sipgate distinguishes between three different billing methods: Prepay, Autoprepay and Postpay.

4.1.1. Prepay method: With this method, the customer first pays a amount determined by them to sipgate (sipgate credit) and can only use chargeable sipgate products corresponding to their sipgate credit after payment has been received. Possible payment methods are bank transfer, direct debit and credit card. Unused sipgate credit does not expire.

4.1.2. Autoprepay method: Autoprepay is identical to the Prepay method, except that the customer's sipgate credit is automatically topped up again when it falls below a minimum amount set by the customer. Possible payment methods for Autoprepay are direct debit and credit card. Unused sipgate credit does not expire.

4.1.3. Postpay method: sipgate reserves the right to offer the customer payment only after sipgate has provided the service, based on a corresponding invoice.

4.1.4. If the service description for the contract booked by the customer provides for the Autoprepay method as the billing method, the customer must ensure that their current bank details or credit card details are stored in their sipgate account. If this is not the case, or if the customer revokes the direct debit authorization or authorization to charge the credit card, a negative balance (a claim by sipgate against the customer) may arise as a result of calls or monthly fees. In this case, sipgate is entitled to request the customer by email to settle their negative balance.

#### 4.2. Payment methods

4.2.1. In addition to bank transfers, sipgate also offers direct debit and credit card payments, provided the customer gives their consent. Participation in the Autoprepay method is only possible, however, if the customer consents to recurring direct debit or credit card payments. The customer must declare this consent when activating the Autoprepay billing method in their account or in writing or by email to sipgate. If charging the selected payment method is unsuccessful, sipgate is entitled to use alternative payment methods stored in the account.

4.2.2. The pre-notification period for SEPA direct debits is one day.

4.2.3. For returned direct debits or collections, the customer must reimburse the costs incurred insofar as they are responsible for them. sipgate will charge the customer for the costs arising in connection with the rejection (third-party charges of the customer's bank as well as charges of sipgate's bank) and collect these from the account balance, unless the customer proves that no damage at all or damage of significantly lesser amount has occurred.

4.2.4. If, in exceptional cases, the customer pays in another way, for example in the event of late payment due to a returned direct debit or insufficient funds, payment shall only be deemed to settle the debt if the customer has sufficiently stated the purpose of payment (in particular the invoice number or a comparable, unique booking code from sipgate) when making the payment. This applies accordingly to payments made by third parties.

4.2.5. sipgate reserves the right to offer the customer additional payment methods (e.g. PayPal) in addition to direct debit or credit card payments.

#### 4.3. Form of invoice

4.3.1. sipgate issues invoices exclusively as PDF files by email or for download. It is not possible to issue invoices in paper form.

4.3.2. The customer agrees to receive their invoice by email and is advised that confidential data transmission over the internet cannot be guaranteed. For this reason, sipgate invoices do not contain itemized call details. These can be retrieved separately by the customer.

4.3.3. The mandatory information on the invoice (Section 14(4) VAT Act) is included in the invoice based on the information provided by the customer in their sipgate account. The customer is obligated to keep this information up to date. sipgate is not obligated to issue invoices that deviate from this information.

#### 4.4. Due date and default

4.4.1. Claims for ongoing contracts that arise at monthly intervals (or at other regular intervals) become due on the 1st day of each month (or period), unless otherwise stipulated in the service description. Claims that do not arise at regular intervals become due upon receipt of the invoice by the customer.

4.4.2. The statutory provisions apply in the event of default.

4.4.3. If the customer is in default, sipgate is entitled to block the service in accordance with Section 61 (3) et seq. of the TKG.

4.4.4. If the customer is a consumer (within the meaning of Section 13 of the German Civil Code (BGB)) and is in default, interest shall be charged at five percentage points above the respective base interest rate of the European Central Bank. If the customer is an entrepreneur (within the meaning of Section 14 BGB), eight percentage points above the base rate shall be charged. sipgate reserves the right to assert further claims due to late payment (e.g. reminder fees).

4.4.5. After eight weeks from receipt of the invoice, sipgate is entitled to delete the connection data on which the invoice is based, which means that subsequent objections can no longer be considered. This also applies accordingly if the customer requests the early deletion of the connection data from sipgate. A complete review of the invoice is therefore only possible as long as the customer's connection data is stored in full.

4.4.6. The customer may only offset claims against sipgate GmbH with claims that have been legally established or are undisputed.

#### 4.5. Objections

4.5.1. The customer must carefully check sipgate's invoices. The customer must raise objections to the amount of the invoice in writing no later than eight weeks after receipt of the invoice.

If the customer has a credit balance with sipgate which sipgate uses to offset base fees and telephone charges, objections to the offset must, notwithstanding sentence 1, be raised no later than eight weeks after the end of the month in which the charges arose. The amount of the offsetting amounts can be found in the itemized connection statement.

The due date of the invoice amount is not affected by the raising of objections.

4.5.2. Objections to the invoice or the offset against the credit balance are excluded if the relevant traffic data have already been deleted within the statutory periods (eight weeks) or at the express request of the customer before the objections were raised.

4.5.3. If objections are not raised within the eight-week period under no. 4.5.1, the invoice/offset against the credit balance is deemed to have been approved by the customer. sipgate points this legal consequence out in the invoices.

4.5.4. In the case of justified objections raised in good time, any overpayment will first be offset against outstanding payment claims of sipgate. If there are no outstanding payment claims, a credit will be issued.

### 5. Data protection

5.1. The legal basis for handling the customer's personal data includes, among others, the General Data Protection Regulation (GDPR), the Federal Data Protection Act (BDSG), the Telecommunications Act (TKG) and the Telecommunications-Telemedia Data Protection Act (TTDSG). Personal data is collected, processed or used only if the data subject has consented or the TTDSG or another legal provision orders or permits this.

5.2. Data processing is therefore particularly permissible insofar as it is necessary. This is necessary for the establishment and design of the contractual relationship (master data), for the provision of telecommunications services (connection data), and for their billing (billing data).

5.3. sipgate observes telecommunications secrecy in accordance with the statutory requirements.

5.4. Detailed information on the handling of personal data by sipgate can be found in our [Privacy Policy](http://www.sipgate.de/team/datenschutz), which is also part of the sipgate T\&Cs.

5.5. The customer commissions sipgate to maintain monthly itemized connection records, which the customer can access via the administrator account. These records list all chargeable connections individually, including date, destination number, start and duration of the connection, and the charge for the individual connection. The numbers of the connections are either shortened by the last three digits or shown in full length, depending on the customer's choice. The customer may also completely deactivate the itemized connection record in their administrator account. If the customer does not exercise their right to choose, the entries will be shown in full.

The customer undertakes to inform all current and future co-users of their sipgate account, or, in the case of business use, all current and future employees, of this without delay and to comply with the co-determination rules.

5.6. The customer commissions sipgate to store the master data (time, duration) of telephone calls, faxes and SMS messages entering or leaving via sipgate, independently of the itemized connection record, for the call list/event list and to make it available to the respective user on their user interface.

5.7. sipgate deletes customer data insofar as the customer has given a corresponding instruction, but only insofar as this is permitted under the TKG or other legal provisions. If objections have been raised, sipgate is entitled to retain the traffic data until the objections have been finally clarified.

### 6. Liability

6.1. sipgate's liability for financial losses is limited to a maximum of €12,500 per customer. In relation to all customers, liability is limited to €30 million per single act or per single damaging event. If the amounts payable to several customers as a result of the same event exceed the maximum limit, compensation shall be reduced in proportion to the total amount of all compensation claims relative to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally.

6.2. Liability for consequential costs arising from emergency calls outside the stated place of residence or business is excluded.

6.3. In all other respects, sipgate is liable only for gross negligence or intent, unless there is a breach of an essential contractual obligation (so-called cardinal obligation). In the event of a slightly negligent breach of a cardinal obligation, liability is limited to such damages typical of the contract that were reasonably foreseeable at the time the contract was concluded.

6.4. sipgate's liability for warranted characteristics as well as under the provisions of the Product Liability Act and for personal injury (life, body, health) remains unaffected by the above provisions.

6.5. To the extent that sipgate's liability is effectively excluded or limited, this also applies to the personal liability of employees, other staff, bodies, representatives and vicarious agents of sipgate.

6.6. sipgate's obligation to perform applies only if sipgate itself has been supplied with corresponding advance services in accordance with the contract and in due time and has not breached any related duties of care. In the event of service disruptions due to force majeure, sipgate shall in any case be released from its obligation to perform.

### 7. Liability for the use of AI applications by customers

7.1. sipgate provides AI applications that can be used by customers for automated communication with their end customers (e.g. initial telephone contact by AI agents). The systems comply with the requirements of the EU AI Act and are regularly checked for functionality and legal compliance. AI systems are highly complex systems that are subject to continuous development. Incorrect, undesired or misleading results therefore cannot be ruled out - even if the AI system operates within its specific specifications.

7.2. sipgate is not liable for damages arising from the use of the AI applications in the relationship between the customer and their end customers, provided that sipgate has properly provided and documented the systems. In particular, sipgate assumes no liability for incorrect information, misunderstandings or omitted notices arising through the AI in customer contact.

7.3. The customer is obligated to check the AI applications for suitability for the respective use case before productive use and to ensure that the legal information, transparency and documentation obligations toward their end customers are fulfilled.

7.4. sipgate is liable only in cases of intentional or grossly negligent conduct and in the event of breaches of essential contractual obligations. Any further liability, in particular for indirect damages or loss of profit, is excluded.

7.5. The customer shall indemnify sipgate against all third-party claims asserted in connection with the use of the AI applications toward end customers, unless these are based on a breach by sipgate of statutory or contractual obligations.

### 8. Changes to fees, the General Terms and Conditions (T\&Cs) and the service description

8.1. sipgate charges the customer the fees applicable at the time the contract is concluded and is generally bound by them. The agreed fees may only be increased by sipgate with effect for the future in the following cases:

* in the event of changes to the VAT rate, sipgate is entitled to adjust the fees accordingly to reflect the change,
* if the Federal Network Agency or another authority validly requires a fee increase, sipgate may amend the fees in accordance with the requirements and,
* if third parties from whom sipgate obtains the necessary advance services for the performance of the services owed under this contract increase their prices, sipgate may pass this price increase on to the customer.

A prerequisite for any increase in fees by sipgate is that sipgate notifies the customer of the change in fees by email at least six weeks before it takes effect and explains the reason for the increase.

8.2. If the customer is a consumer (within the meaning of Section 13 BGB), the customer has an extraordinary right of termination in the event of an increase in net fees, which becomes effective at the time of the relevant fee change. If the customer does not exercise this right of termination within four weeks of receiving notice of the fee increase, the change is deemed approved. sipgate expressly points this out again in the notice of the fee increase.

In the event of changes to VAT, sipgate is entitled to adjust the fees accordingly to reflect the change, without this giving rise to a right of termination for the customer.

8.3. If the customer is an entrepreneur (within the meaning of Section 14 BGB), sipgate is entitled, irrespective of no. 8.1, at its reasonable discretion and taking into account general market developments (in particular internal advance service prices) to adjust the fees at any time with effect for the future. This applies in particular if sipgate's purchase prices change.

8.4. sipgate is entitled to amend these T\&Cs insofar as this does not affect essential provisions of the contractual relationship and is necessary to adapt to developments that were not foreseeable at the time the contract was concluded and whose non-consideration would significantly disturb the balance of the contractual relationship. Essential provisions are in particular those concerning the type and scope of the contractually agreed services and the term, including the provisions on termination.

Furthermore, adjustments or supplements to the T\&Cs may be made insofar as this is necessary to remedy difficulties in the performance of the contract due to regulatory gaps that arose after the contract was concluded. This may be the case in particular if case law changes and one or more clauses of these T\&Cs are affected. If the change results in a deterioration for the customer, it is only permissible on the condition that sipgate informs the customer by email no later than six calendar weeks before it takes effect.

8.5. The service description may be changed if this is necessary for an important reason, the customer is not placed at a disadvantage compared to the service description included at the time the contract was concluded (e.g. maintenance or improvement of functionalities), and there is no significant deviation from it. An important reason exists if there are technical innovations on the market for the services owed or if third parties from whom sipgate obtains the necessary advance services for the performance of its services change their service offering. If the change results in a disadvantage to the customer, it is only permissible on the condition that sipgate informs the customer by email no later than six calendar weeks before it takes effect.

8.6. Intended changes to the T\&Cs and the service description under clauses 8.5 and 8.6 will be communicated to the customer by email at least six weeks before they take effect. If the change to the T\&Cs or the service description is disadvantageous to the customer, the customer has an extraordinary right of termination at the time the changes take effect. If the customer does not terminate in writing or by email within four weeks of receipt of the notice of change, the changes become part of the contract at the time they take effect. The customer is expressly informed of this consequence in the notice of change.

### 9. Maintenance and fault-clearing service

sipgate offers its customers the opportunity at any time to access frequently asked questions and their answers as well as various configuration instructions via its help center, and to contact customer support in writing or by phone via the contact form and, for example, report faults.

### 10. Final provisions

10.1. Deviating General Terms and Conditions of the customer do not apply even if sipgate does not expressly object to them.

10.2. Free additional services provided by sipgate are not contractual components. sipgate may change and/or discontinue these services at its own discretion. This is subject to any other agreements with the customer.

10.3. The customer may only transfer the rights and obligations under this contract to a third party with the prior written consent of sipgate.

10.4. The use of products and services of sipgate GmbH in the territory of, or by citizens of, the United States of America (USA) is excluded.

10.5. The use of sipgate is excluded in those countries where the use of sipgate's service is not permitted.

10.6. The law of the Federal Republic of Germany applies exclusively between the customer and sipgate, as it applies between domestic persons, excluding the UN Convention on Contracts for the International Sale of Goods, unless mandatory law requires the application of another legal system.

10.7. The place of jurisdiction is Düsseldorf, provided the customer is a merchant.

10.8. sipgate is entitled to transfer the customer's master data to third parties insofar as this is necessary for the purpose of assigning or collecting claims. Statutorily permitted transmission of further customer data for the purpose of debt collection remains unaffected.

10.9. sipgate is entitled to have the services performed by third parties as subcontractors.

10.10. Locations created in the sipgate account are verified using a suitable procedure.

### 11. Customer information pursuant to the Telecommunications Act (TKG)

#### 11.1. Emergency call (landline)

The emergency numbers 110 and 112 can be reached via sipgate. These are activated for your stored address. The customer must regularly check whether the personal or business details are correct and change them if necessary.

Only if the name and address are correct at the time an emergency call is made can proper emergency call functionality, in particular reaching the nearest fire or police station, be ensured. If you use sipgate from a location other than the stored address (nomadic use), emergency call service may not be possible at all or only if you can tell the emergency call center your location and your name. So-called “death rattle calls” are not possible.

#### 11.2. Emergency call (mobile network)

In Germany, an emergency call to the Europe-wide emergency number 112 and to the national emergency number 110 valid in Germany can only be made with an inserted and valid SIM card. Different rules may apply outside Germany. In the event of an emergency call to 112 and 110, information about the caller's location may also be transmitted to the responsible emergency call answering point. In addition to the general emergency numbers 110 and 112, customers in the coastal areas of the North and Baltic Seas can dial the SAR distress call (sea emergency call) on 124 124. The SAR distress call does not replace the usual maritime radio services.

#### 11.3. Conciliation procedure

Customers in dispute with sipgate can initiate conciliation proceedings at the Federal Network Agency by submitting an application in accordance with Section 68 TKG.

The Federal Network Agency regulates the details of the conciliation procedure in a conciliation ordinance that it publishes.

EU Commission platform for online dispute resolution: [www.ec.europa.eu/consumers/odr](https://webgate.ec.europa.eu/odr/main/index.cfm?event=main.home.show\&lng=DE\&ampDeviceId=b06aff2e-fdc0-4bd9-9e23-ecaea52e6388\&ampSessionId=1767690360698)

#### 11.4. Inclusion in public subscriber directories

The customer may at any time request to be entered free of charge in a publicly accessible subscriber directory with their phone number, surname, first name and address, or have their entry deleted or changed.

#### 11.5. Security or integrity of telephony and data processing systems

When providing its services, sipgate places great importance on the security and integrity of its systems and data, as well as the proper functioning of the systems used. sipgate's infrastructure is always kept up to date with the latest technology and complies with the current technical guidelines and applicable standards. In the event of breaches or discovered vulnerabilities, measures are taken immediately to stop them and prevent them in the future. This applies in particular both to potential attacks on sipgate's network and to the protection measures proposed and implemented. sipgate has a security concept approved by the Federal Network Agency.

sipgate has implemented numerous technical and organizational measures in order to be able to prevent security or integrity breaches, threats and vulnerabilities and respond to them at an early stage.

Examples of such measures are:

* sipgate regularly checks the technical equipment used for possible security vulnerabilities in order to identify and remedy possible threats or vulnerabilities at an early stage.
* sipgate continuously monitors published security vulnerabilities.
* sipgate regularly monitors and maintains the technical equipment used and operates automatic monitoring for the main systems around the clock, 365 days a year, so that it can respond quickly to acute security or integrity breaches at any time.
* sipgate operates its own Network Operation Center, which monitors, among other things, the main network platforms and systems.
* sipgate implements the current technical guidelines and standards aimed at implementing technical measures to ensure integrity, i.e. to be able to identify corrupt data as such and, where necessary, retransmit the data.
* sipgate informs the affected customers about a breach of security or integrity.
* sipgate has implemented and integrated an emergency concept. If any vulnerabilities are identified at sipgate in any form, they are remedied immediately.

#### 11.6. Blocking of certain number ranges

The national number ranges 0137, 0138, 01212, 0181, 0185, 0188, 0900 and 118xx are blocked. Individual blocking of certain national, international numbers and number ranges as well as certain special numbers is not possible.

#### 11.7. Caller ID suppression

The customer has the option of permanently or temporarily suppressing the display of their phone number to the called party, if the function is supported by their end device.

#### 11.8. Blocking of number ranges/services provided in addition to the connection

The customer has the possibility to block certain number ranges under Section 61(1) as well as a right to block the use and billing of services provided in addition to the connection via the mobile connection under Section 61(2) TKG.

#### 11.9. The use of the call by call and preselection service of netzquadrat Gesellschaft für Telekommunikation mbH (01064) is possible. Further call by call and preselection services are currently not available.
