If a zone's sipSigPort is configured for transportProtocolsAllowed = sip-tls-tcp , SBC the increments the configured portNumber by 1 and uses it as the new port number for SIP over TLS signaling. SBC The 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 , SBC the listens on TCP port 5061 for SIP over TLS. |
