I am using a 2811 CCME Router which has Vic-2FXO, Vic-2FXS. I connect the CCME router to Panasonic PBX via FXO port, and I config to make the calls drom CCME Router to PBX and versus. It's OK when I make a call from PBX to CCME router, however it delay 12s when I make a call from CCME Router to PBX. Please help me, I don't know if that problem is FXO disconnect port problem.
I attach 2 config files.
