Re: CME - can not dail PSTN (out going calls )

Hi Aslam,

1.Could you please explain the complete network topology and please upload the debugs that you collected with the called and the calling number.Also attach the relevant controller config, serial interface config, dial-peer etc to analyze.

2.Cause value 34 implies that there is a mismatch in channel mapping either on your end or the provider's end.

3.So we need to check if we are sending this error message or if we are receiving this error message.

If we are receiving this error message, then provider needs to correct the channel mapping on their end.

4.If we are using H323 then try to change the isdn channel order using this command on gateway

"isdn bchan-number-order" as well as try changing the channel order from under the gateway on CUCM, if we have a CUCM in the network topology.

.

5.Make sure we have configured only those channels that we are allowed to inside a Controller for pri group command.

Thanks & Regards,

Mudit Mathur
