I believe the problem maybe due to your telco? Can verify the status of your ISDN PRI controller.

There should not be any problem with the destination-pattern match, and I assume that you get the secondary dial-tone after you dial 9?

At this point the call should be routed off-net, however I assume there is a pause before you receive fast-busy?

Can you post the show controller output and show isdn status.

Can you also post a debug isdn q931 when you attempt an outbound call?

Hope this helps.


Pls rate helpful posts.

Additionally i wanted to clarify whether COR is same as call blocking feature.If not call blocking is used on date and time sequence to block calls..rite ? In this case is it like FAC ?

please do not duplicate your posts or keep them separated. you already have another one on the 9 busy tone. the answer is really simple, if you don't have ISDN up the as soon as dial-peer matches returns fasts busy because it cannot route the call.

FAC is not available in CME, this has been asked many many times before and there are a lot of posts on this. please use the search NetPro option for previous answers.

just one of the many posts available already, please use Search NetPro option
