Note

If a zone's sipSigPort is configured for transportProtocolsAllowed = sip-tls-tcp, the SBC increments the configured portNumber by 1 and uses it as the new port number for SIP over TLS signaling. The SBC then opens a TCP socket for SIP over TLS for the new TCP port number.

Example: When sipSigPort is configured with a portNumber of 5060 and transportProtocolsAllowed = sip-tls-tcp, the SBC listens on TCP port 5061 for SIP over TLS.
