Source note · Setting up site survivability for Webex Calling
For certificate-based trunking the colocation configuration differs only in Local Gateway trunk and tenant parts: a TLS profile with cn-san validate bidirectional, a SIP OPTIONS keepalive profile over TLS, and a DNS session target for the Webex SIP connect address.
Checked 2026-09-24
Configuration of colocation for certificate-based trunking is similar to registration-based trunking, except for those specific to Local Gateway trunk and tenants.
