We use CM 4.1 and 2811 voice gateway. We have two FCTs. One is working properly, but another one has a problem(same vendor, same model, same config on 2811, H323 gateway).
When the problematic number is called from outside, fxo port cannot transfer the call in. You hear the first word of the prompt, then call drops.I tried the FCT on different FXO ports, it didnt work. And i tested the FXO port with different lines, it works. The interesting situation is that when i plug an analog phone to FCT, it works well. And i should add this info; we can properly call outside using the problematic FCT over FXO port.
