I have about 10-15 Polycom 501's running on 3cx v11. I cannot get the intercom feature to work. All that is currently happening when I try to intercom a phone is the phone rings.
The Polycom phones are running version 3.1.7
I ALWAYS struggle to get my IP501's registered to 3CX via their provisioning templates.
Do you have them registered? Could you give me the template that you use?
Currently I've got them hitting a Linux server with a trivial FTP server on it that passes the credentials of the 3CX.
Thanks in advance!
