The contract for the use of sipgate services is concluded when sipgate accepts the customer's order for the provision of the services. Acceptance is deemed to have been 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 by that time. The customer is bound by their application for 5 working days. 1.1.2. The 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. The 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 a 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 is unreasonable for sipgate to wait for the expiry of the notice period. Such a case exists, among others, if the customer: * creates a sipgate account under a false name or false identity and/or * misuses the sipgate account, the connection or the assigned phone number and/or * if insolvency proceedings are opened against the customer's assets or the customer files an application for the opening of insolvency proceedings and/or * direct debit chargebacks occur after debits. 1.3.2. In addition, sipgate is entitled to an extraordinary right of termination in the event of changes to the legal basis of this contract, or orders and/or directives affecting the contract issued by authorities, courts or other public bodies, provided that these lead to a situation in which it becomes 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 upon termination of the contract 1.4.1. If, at the time the termination takes effect, the customer has a credit balance in their sipgate account, sipgate undertakes to reimburse this to the customer upon request. The customer can submit the request via their sipgate account. The reimbursement by sipgate will be made by way of a credit to the specified bank or credit card account of the customer. 1.4.2. Any other reimbursement of sipgate credit is excluded. #### 1.5. Inactive accounts If the customer has a sipgate account that has not been 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 duties to cooperate 2.1. The customer is responsible for maintaining an internet connection 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 becomes aware of any unintended or abusive use, they must inform sipgate immediately. 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, to check it regularly, and to inform sipgate immediately of any changes to their email address. 2.4. If there are changes affecting the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed immediately. This obligation to report applies in particular to the following points: * Change of the customer's place of residence/company headquarters (among other things necessary for the correct localization of emergency calls). Further information at: [Instructions for placing emergency calls](http://www.sipgate.de/team/nutzungsbedingungen#emergency_call) * Change of the customer's email address * for payments in the autoprepay process, the bank details and credit card information. 2.5. The customer may only use the connections to sipgate as intended and in accordance with the (telecommunications) laws and regulations in their currently valid version. The customer is obliged not to misuse the telecommunications services offered by sipgate for purposes that conflict with the legal provisions, the relevant [sipgate service description](https://www.sipgate.de/leistungsbeschreibung) or the sipgate Terms and Conditions. 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 to 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 bind 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 necessary, be transferred to a network operator other than the one used at the time the contract was concluded. This entails no costs and no 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 by 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 cannot otherwise be resolved by sipgate 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 there is misuse by the customer or a user authorized by them (e.g. breaches of 2.5, 2.6, 2.10 or comparable breaches) and the customer does not cease the misuse within a reasonable period despite a request from 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 for the costs of the blocking/deletion. The customer is obliged to pay the basic charges incurred during a blocking if they are responsible for the blocking. ### 3. Connection charges 3.1. The customer is obliged to pay for any use of their connection for which they are responsible. 3.2. The customer is also obliged to pay the charges caused by the user or co-user. This also applies in the case of abusive use, unless the customer proves that they are not at fault for any breach of duty. 3.3. The obligation to pay does not apply if facts justify the assumption that third parties have influenced the billed connection charge through unauthorized modifications to public telecommunications networks. 3.4. The charges for the VoIP service are based on 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 currently valid 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: Under this method, the customer first pays sipgate an amount determined by the customer themselves (sipgate credit) and can only use paid sipgate products according 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 performance by sipgate on the basis of an appropriate invoice. 4.1.4. Where 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 the 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 by email that the customer settles 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. However, participation in the Autoprepay method is only possible if the customer consents to recurring direct debit or credit card payments. The customer must declare this consent when activating the Autoprepay billing procedure in their account or in writing or by email to sipgate.If debiting 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 incurred in connection with the return (third-party charges of the customer's bank and charges of sipgate's bank) and debit them from the account balance, unless the customer proves that no damage whatsoever or only significantly less damage was incurred. 4.2.4. If, in exceptional cases, the customer pays by other means, for example in the event of late payment due to a returned direct debit or insufficient funds, payment shall only be deemed to have discharged the debt if the customer has sufficiently specified the purpose of payment (in particular the invoice number or a comparable, unambiguous booking code from sipgate) when making the payment. This applies accordingly to payments 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 the invoice 4.3.1. sipgate issues invoices exclusively as PDF files by email or for download. Issuing an invoice on paper is not possible. 4.3.2. The customer agrees to the transmission of their invoice by email and is informed that confidential data transmission over the internet cannot be guaranteed. For this reason, sipgate invoices do not include itemized call records. These can be accessed separately by the customer. 4.3.3. The mandatory information in the invoice (Section 14 (4) of the German VAT Act) is included in the invoice based on the information provided by the customer in their sipgate account. The customer is obliged to keep this information up to date. sipgate is not obliged to create invoices that differ 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) are due on the 1st day of each month (or period), unless otherwise regulated 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 to default. 4.4.3. If the customer is in default, sipgate is entitled, in accordance with Section 61 (3) et seq. of the TKG, to suspend the service. 4.4.4. If the customer is a consumer (within the meaning of Section 13 of the German Civil Code) and is in default, interest at five percentage points above the respective base interest rate of the European Central Bank will be charged. If the customer is an entrepreneur (within the meaning of Section 14 of the German Civil Code), eight percentage points above the base interest rate will 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 underlying the invoice, which means that subsequent objections can no longer be considered. This also applies if the customer requests 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 are 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 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 that sipgate offsets against basic charges and telephone charges, objections to the offsetting must, deviating from 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 call record. The due date of the invoice amount is not affected by the raising of objections. 4.5.2. Objections to the invoice or the offsetting against the credit balance are excluded insofar as the relevant traffic data have already been deleted within the statutory periods (eight weeks) or at the customer's express request 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/offsetting against the credit balance is deemed approved by the customer. sipgate points out this legal consequence in the invoices. 4.5.4. In the event 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 note 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 and Telemedia Data Protection Act (TTDSG). Personal data will only be collected, processed or used if the data subject has consented or if the TTDSG or another legal provision requires or permits it. 5.2. Data processing is permissible in particular where necessary. This is necessary for the establishment and structuring of the contractual relationship (inventory data), for the provision of telecommunications services (connection data), and for their billing (billing data). 5.3. sipgate respects telecommunications secrecy in accordance with statutory requirements. 5.4. Detailed information on how sipgate handles personal data can be found in our [privacy policy](http://www.sipgate.de/team/datenschutz), which is also part of the sipgate Terms and Conditions. 5.5. The customer commissions sipgate to provide a monthly itemized call record, which they can access via the administrator account. This record lists all chargeable connections individually, including the date, destination number, start and duration of the connection, and 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 can also completely deactivate the itemized call record in their administrator account. If the customer does not exercise their right of choice, the full number will be shown. 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, immediately and to comply with the co-determination rules. 5.6. The customer commissions sipgate to store the basic data (time, duration) of telephone calls, faxes and SMS messages to or from sipgate, regardless of the itemized call record, for the call list / event list and to make it available to the respective user on their user web interface. 5.7. sipgate deletes customer data if the customer issues a corresponding request, but only to the extent permitted by 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 resolved. ### 6. Liability 6.1. sipgate's liability for financial losses is limited to a maximum amount of €12,500.00 per customer. In relation to all customers, liability is limited to €30 million per uniform act or uniform damaging event. If the amounts payable to several customers based on the same event exceed the maximum limit, compensation shall be reduced in proportion to the ratio of the total amount of damage claims to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally. 6.2. Liability for consequential costs resulting from emergency calls made outside the stated place of residence or business premises is excluded. 6.3. In all other respects, sipgate is only liable for gross negligence or intent, unless there is a breach of a material contractual obligation (so-called cardinal obligation). In the event of a slightly negligent breach of a cardinal obligation, liability is limited in amount to such typical contractual damage as was 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. Where sipgate's liability is effectively excluded or limited, this also applies to the personal liability of sipgate's employees, other staff, organs, representatives and vicarious agents. 6.6. sipgate's obligation to perform applies only if sipgate itself has been supplied with the relevant preliminary services in accordance with the contract and on time and has not breached any duties of care in this respect. In the event of disruptions to performance due to force majeure, sipgate is released from the obligation to perform in any case. ### 7. Liability when customers use AI applications 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 cannot therefore 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 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 from the AI in customer contact. 7.3. The customer is obliged to check the AI applications for suitability for the respective use case before productive deployment and to ensure that the statutory obligations regarding information, transparency and documentation towards their end customers are fulfilled. 7.4. sipgate is only liable in the event of intentional or grossly negligent conduct and in the event of breach 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 claims by third parties asserted in connection with the use of the AI applications vis-à-vis end customers, insofar as these are not based on a breach by sipgate of statutory or contractual obligations. ### 8. Changes to charges, the General Terms and Conditions (GTC) 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 charges may only be increased by sipgate for the future in the following cases: * in the event of changes to the VAT rate, sipgate is entitled to adjust the charges accordingly, * if the Federal Network Agency or another authority requires a fee increase in a binding manner, sipgate may change the charges in accordance with the requirements and, * if third parties from whom sipgate obtains preliminary services necessary for the provision of the services owed under this contract increase their prices, sipgate may pass on this price increase to the customer. A prerequisite for an increase in charges by sipgate is that sipgate informs the customer of the change in charges 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 of the German Civil Code), the customer has an extraordinary right of termination in the event of an increase in net charges, which takes effect at the time of the relevant change in charges. If the customer does not exercise this right of termination within four weeks of receipt of the notification of the charge increase, the change shall be deemed approved. sipgate expressly points this out again in the notification of the charge increase. In the event of changes to VAT, sipgate is entitled to adjust the charges accordingly 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 of the German Civil Code), sipgate is entitled, regardless of No. 8.1, at its reasonable discretion and taking into account general market developments (in particular also internal preliminary service prices), to adjust the charges at any time for the future. This applies in particular if sipgate's purchase prices change. 8.4. sipgate is entitled to amend these Terms and Conditions insofar as this does not affect essential provisions of the contractual relationship and is necessary in order to adapt to developments that were not foreseeable at the time the contract was concluded and whose failure to be taken into account would significantly disturb the balance of the contractual relationship. Essential provisions are, in particular, those concerning the nature and scope of the contractually agreed services and the term, including the provisions on termination. Furthermore, adjustments or additions to the Terms and Conditions may be made insofar as this is necessary to remedy difficulties in performing the contract due to gaps in the rules 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 Terms and Conditions are affected. If the change results in a deterioration for the customer, a change 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 with the service description included at the time the contract was concluded (e.g. retention or improvement of functionality) and there is no significant deviation from it. There is an important reason if there are technical innovations on the market for the services owed or if third parties from whom sipgate obtains preliminary services necessary to provide its services change their service offering. If the change results in a deterioration for the customer, a change 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 Terms and Conditions 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 Terms and Conditions or the service description proves disadvantageous for 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 will be specifically informed of this consequence in the notice of change. ### 9. Maintenance and fault clearance service sipgate offers its customers the opportunity at any time to access frequently asked questions and answers as well as various configuration instructions via its help center, to contact customer service in writing or by telephone via the contact form, and, for example, to report faults. ### 10. Final provisions 10.1. Any deviating General Terms and Conditions of the customer shall not apply, even if sipgate does not expressly object to them. 10.2. Free additional services provided by sipgate do not form part of the contract. 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 arising from this contract to a third party with sipgate's prior written consent. 10.4. The use of products and services of sipgate GmbH within 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 in which the use of sipgate's service is not permitted. 10.6. The law of the Federal Republic of Germany shall apply 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 purposes of assignment or collection of claims. Any legally permissible transfer of further customer data for the purpose of debt collection remains unaffected. 10.9. sipgate is entitled to provide the services through third parties as subcontractors. 10.10. Locations created in the sipgate account are verified using a suitable procedure. ### 11. Customer information pursuant to the 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 check at regular intervals 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 placed can proper emergency call functionality, in particular the ability to reach the nearest fire or police station, be guaranteed. If you use sipgate from a different location than the stored address (nomadic use), emergency service may not be available at all or only if you can tell the emergency call center your location and your name. So-called 'gasp calls' are not possible. #### 11.2. Emergency call (mobile) In Germany, an emergency call to the Europe-wide emergency number 112 and to the national emergency number 110 applicable in Germany can only be placed with a valid SIM card inserted. Outside Germany, other rules may apply. 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 center. In addition to the general emergency numbers 110 and 112, customers in the coastal areas of the North Sea and Baltic Sea can dial the SAR alarm call (maritime emergency call) at 124 124. The SAR alarm call does not replace the usual maritime radio services. #### 11.3. Arbitration procedure Customers in dispute with sipgate can initiate an arbitration procedure at the Federal Network Agency by submitting an application pursuant to Section 68 TKG. The Federal Network Agency regulates the details of the arbitration procedure in an arbitration code, which 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\&DeviceId=b06aff2e-fdc0-4bd9-9e23-ecaea52e6388\&SessionId=1767690360698) #### 11.4. Listing in public directories of subscribers The customer may at any time request to be entered free of charge in a public directory of subscribers with their phone number, surname, first name and address, or to 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 correct functioning of the systems used. sipgate's infrastructure is always kept up to date with the latest technology and meets the current technical guidelines and valid standards. In the event of violations or detected 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 proposed and implemented protective measures. sipgate has a security concept that has been approved by the Federal Network Agency. sipgate has implemented numerous technical and organizational measures in order to prevent security or integrity breaches as well as threats and vulnerabilities and to be able to respond to them at an early stage. Examples of such measures are: * sipgate regularly checks the technical devices used for possible security vulnerabilities in order to be able to identify and rectify potential threats or vulnerabilities at an early stage. * sipgate continuously monitors published security vulnerabilities. * sipgate regularly monitors and maintains the technical devices used and has automatic monitoring for the key systems around the clock, 365 days a year, so it can react 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. among other things, being able to recognize corrupted data as such and, if 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 vulnerabilities are identified at sipgate in any form whatsoever, they are remedied immediately. #### 11.6. Blocking certain number ranges The national number blocks 0137, 0138, 01212, 0181, 0185, 0188, 0900 and 118xx are blocked. Individual blocking of certain national, international number ranges and number blocks as well as certain special numbers is not possible. #### 11.7. Suppression of caller ID 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 terminal device. #### 11.8. Blocking number ranges/services provided in addition to the connection The customer has the option of blocking certain number ranges pursuant to 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 pursuant to Section 61(2) TKG. #### 11.9. Use of the call by call and preselection service of netzquadrat Gesellschaft für Telekommunikation mbH (01064) is possible.
