Call not end-to-end ISDN

I'm having trouble with International calling. Currently have a 3725 MGCP PRI gateway registed to CM 3.3. The isdn pri is a ATT&T Megacom circuit. Long distance dialing is ok. If I change the Called Party number in CM3.3 to use INternational setting, International dialing works fine, but no LongDistance. Hence the problem.

I tried a number of changes to make this work. The error I attatched is a debug isdn q931 for a International call placed. Basically it is: Call not end-to-end ISDN. Any input would be great.

Re: Call not end-to-end ISDN

It sems like you are sending a called number to the telco that it is not expecting, maybe it is expecting a 011 before the number. What kind of switch type are you using, primary 4ess?

Try adding a 011 before the number and then sending to the telco, or asking your PSTN folks what it is they are expecting in the number.

Re: Call not end-to-end ISDN

We need to strip the 011 on our end. The correct digits are being sent to the Telco. I make successful International calls with the same route pattern when changing the Called number to InternationaL on the MGCP Gateway
