A have a setup with a pbx as external connection to buplic number and VitalPBX with trunk to both external pbx and Cisco CUCM. The external pbx and cucm both have enpoints. On VitalPBX i have a ring group that want to ring on endponits on both external pbx and cucm but it doesn’t when call comes in on a trunk on which the goup has endponints on.
My question: is there a way to get vitalpbx to ring members of a group which are on the same trunk as the incomming call comes in on?
ps. configuring ring groups on external pbx or cucm is not an option for me.
