Frequent Questions

Data privacy

The SIP.TG server infrastructure is secure, stable and productive. But if there are special requirements for the confidentiality of call and account data, or the need to process a huge number of calls with a performance guarantee, we allow you to deploy the infrastructure for the Gateway on your own modules.
The SIP.TG platform can be transparently integrated with any existing infrastructure and products of telecom operators and large companies.
