Frequent questions


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