Debuging H323 Dial-Peers

Today has been a long day. I’ve been trying to get 4 analog DID, and 4 analog DOD lines working on a 2811 with one FXO and one FXS DID card. Some very useful debug commands in this process have been.

debug voip dialpeer all
This allows me to see when I place an outbound call what Dial-peer it is actually hitting and all the detail about it.

Debug vpm all
This gives me the debug output from the FXO and FXS cards. In my case it’s telling me I need to get a hold of the phone company. The lines are supposed to be Ground-start however when my FXO goes off hook it never sees the circuit complete and then just drops the call.
