i have and HQ where there are FXO and Branch offices with FXS. the voip is working like sharm.
the problem happens, when a users in the HQ (FXO) calls another FXO (locally), this should not happen but it must be a miss typing. so i have a problem of Disconnection on the FXO lines.
i am wondering if there is a way to restrict an FXO calling another.!!! i am going to do a corlist but in case there is something else i can do please let me know.
