I have a Polycom conference phone connected to a FXS port on a 2851 running CME7.1. I have configured the port to be controlled by SCCP via the stcapp command. The phone can make and receive internal and external calls without any issues, but I run into problems when trying to conference 3 parties.
1 - Dial 1st party (internal)
2 - Press conference button (hookflash), obtain dial-tone
3 - Dial 2nd party (internal)
4 - Press conference button, get fast-busy tone
5 - The two parties that were phoned are alone on the conference
Below is my config:
timeouts ringing infinity
timing hookflash-in 300 100
dial-peer voice 22 pots
description **Dial Peer for Main Conference Phone**
ephone-dn 47 dual-line
label Main Conf Room
name Main Conf Room
Has anyone got any ideas as to what the problem could be?
