6 SIP Signaling Port

Set the SIP Signaling port, which is a logical address used to send and receive SIP call signaling packets and is permanently bound to a specific zone.

...

Warning

There are a few areas that result in a TLS negotiation issue. One area involves assigning the incorrect port. Ensure the following are accomplished: 

  • Zoom listens on port number 5061 (default setting).

  • Configure port number 5060 on Zoom IP-Peer since Ribbon SBC Core increments the port by 1 when the transport protocol is TLS.
