@hiev, just to clarify… You’re attempting *82+extension number? or *82+Paging&Intercom Code?
If your Paging&Intercom Code has multicast entries, then I assume it’ll use multicast and not SIP to page.
Validate you’re running the latest Yealink firmware. Factory reset the phone and reregister with VitalPBX as a bare minimum, as features.intercom.allow=1 is the factory default anyways. See if that helps.
