Incoming International calls receiving problem.

Unanswered Question
Jul 31st, 2010

Hi Team,

I have ISDN PRI E1 connection and i am able to recieve all international calls except two DID number. But I am able to receive national calls

without having any problem. Also noticed that We are able to recieve international calls from certain countries in these DID number.

Also noticed that call is hitting in the gateway and getting debug isdn q931 output with proper digit and Isdn Type:International.

For testing we replaced the phone with another,but issue has same.

Let me know  either is there any  problem with PBX system or problem with Service Provider.

Thanks in advance for your help!!!!

Best Regards,

Febin S

I have this problem too.

Most likely something with the service provider, but to confirm you will need to collect some debugs.

Is it an MGCP PRI with CUCM? Or PRI to H323?

Hi

Provide the debug outputs " debug isdn q931" and "debug voip ccapi inout" when the incoming call is been made.

This will help you to identify the Release Cause for the Call, based on that you can decide the call failure reason while hitting

the Gateway.
