UC520 cannot be called, but it can call out

Hello everyone,

   I have a problem with my UC 520. The question is as the title says. This is a lab environment. I connect the UC520 to a 3745 using T1 PRI. I have a CIPC register to the 3745 and a 7941 phone register to UC520. The CIPC can call 7941 but the 7941(17184752300) cannot call CIPC(17755011111). I can see the debug isdn q931 from the UC500 and I will paste it here. I will also attach the config file of UC520. Let me know if you need more information.

   The UC520 config might not be very clean because there was a lot of stuff there before we test it. And then we used it to test with CCA too.

  Thank you very much.

William

Since this is a lab scenario. I would remove the PRI connection and use IP session targets for your dial peers.  If the call can connect I would make sure your have isdn protocol-emulate network on the 3745 and isdn protocol-emulate user on the uc520.  the command would be listed under the interface.  Assuming you are using a T1 crossover

Thanks Marcus,

   It would be more difficult to do this in the VoIP way since my lab's topology. I gave up VoIP when I find the connection issue between the two phones. However I use the debug voip ccapi inout command and find out that the route is via dial-peer 6 instead of dial-peer 1.  Then I found out that there is a translation-profile has been implemented. All digits are stripped off after that. I deleted it and everything works. Thanks!
