Overview:
The IMG now supports TLS (Transport Layer Security) to establish a trust with each external SIP gateway or trusted domain. TLS will provide endpoint authentication by using 'Mutual' or 'Two-Way' Authentication on a hop-by-hop basis. With Mutual or Two-Way authentication both the server and its client will use certificates from a Certificate Authority to authenticate each other. The IMG uses a digital certificate for authentication and a public key for encryption/decryption. Once the sender is verified then the receiver will send its certificate to the sender for verification. When all information is verified then the SIP signaling can begin. Below is diagram showing the TLS certification process supported on the IMG.
