Hello,


The problem is with your dial-peer 1. Pots dial-peers by default strip explicitly matched digits. You need to have a forward-digits command under the dial-peer. Example:


dial-peer voice 1 pots

description Local 7 Digit Dialing

destination-pattern 9.......

port 0/2/0

forward-digits 7


dial-peer voice 2 pots

description Local 10 Digit Dialing

destination-pattern 9[2-9].........

port 0/2/0

forward-digits 10


dial-peer voice 2 pots

description Long Distance

destination-pattern 91[2-9].........

port 0/2/0

forward-digits 11


In the above examples, the 9 will be stripped from the dialed digits, and the dial-peer will forward the specified amount of digits depending on which dial peer is matched. If you are just going to use the "9T" destination pattern, then you would just add "forward-digits all" under the dial peer, which will strip the 9, and forward the rest of the dialed digits. Make one of these dial-peers for each of the voice ports that you are using for outbound calls. Also, FYI, the command to debug FXO is "debug vpm signal".


Hope that helped, if so please rate.

Just to add to the fine information you already have. The debug commmands to use with FXO/FXS cards is "debug vpm signal". This will tell you alot especially when paired with "debug voice dialpeer inout"..
