I am currently configured a H.323 GW which contain few FXO port. Normal PSTN line is connected to the FXO port. The PSTN number is assign to one of the IP phone.
My problem is, when i use my mobile phone to call this PSTN line, the IP phone ring, but it shows UNKNOWN NUMBER. By right it should display my mobile number as the incoming number. I tried to grab the debug info, so that i can see whether i manage to see what is the incoming number. for ISDN PRI E1, we use debug isdn q931, but for this PSTN FXO, i cannot find the command.
Any idea? do i miss out anything in CM?
