SIP Proxy Testing

 

An SIP proxy is a key component of a SIP-based network. It is responsible for handling the setting up, negotiating resources for, tearing down and maintaining SIP sessions, and can also act as a registrar or a redirect server.

EXFO's SIP Proxy solution tests various features of the SIP proxy, while carrying out performance, scalability and reliability tests.
