VG224 has sip stack
I followed this solution: Use a Cisco router FXS as PBX subscriber - #7 by michelpy
without success unless I addedd trusted ip subnet into
> voice service voip => ip address trusted list
as from IOS15.1 was introduced against toll-fraud
Now pjsip endpoint is available and works as expected
Question: VG224 peer authentication username MUST be of at least 4 characters, it means at least 4 digit extension on freepbx, having 3 digit extensions can I set a sip(pjsip) username that differs from ext.no somewhwere ??
