Source note · Unified CM SIP trunks and security profiles
Cisco's LGW guide says to set the SIP trunk security profile incoming port to 5065 for the Webex Calling trunk in Unified CM. Unified CM then accepts messages on 5065 and puts 5065 in the Via header of messages it sends to the LGW.
Checked 2026-09-24
This allows incoming messages on port 5065 and populate the VIA header with this value when sending messages to the Local Gateway.
