See:

http://cisco.com/en/US/tech/tk652/tk90/technologies_configuration_example09186a008019d649.shtml

Note: the actual configuration can be made smaller that in the example. Just configure with cor the incoming DP for FXS (if not using FXS in SCCP mode), and the DP matching FXO.

Hope this helps, please rate post if it does!

Do you have CM? And if so which protocol are you using to the router ?

i have CCM 5.1 and i use H323 protcol.

thanks very much

Then he COR configuration still applies. Set a "station number" under voice-port and match it with "answer-address" on a pots DP. That will be your incoming DP.

Another technique is that you configure a translation profile again on the FXS voice port, and change the called number so that it can't dial outside.

Hi,

1. DP 52 needs corlist incoming, not outgoing

2. DP 52 does not need port

3. Have you set station number under voice port 2/0/0 ?

4. unrelated to the problem, you don't need any of the progress_ind commands under DP, these are for ISDN only, and not even always.

5. suggest you use trunkgroup for port 0/0/2, 0/0/3, and 0/1/0 ? That will allow you using a single DP, simplifying much the configuration.
