Hello,
We have installed a SMBC at a school which intercom system worked with their previous PBX. They use the handsets to make a call to a classroom.
It is SIP intercoms, each intercom has its own ext number. I have configured the intercoms to work.
The problem is that when you dial the intercom there is no sound indicating the incoming connection. It connects immediately without making any sound.
Is there a possibility to change this or is there a function code that can be used? It worked fine with their previous PBX.
