Dial-Peer Configuration

[Robert Craig]

I recently added a dial-peer that would allow my CME users to dial local calls, instead of dialing the area code first. I wanted them to be able to just dial 7 digit calls. Well, now that I've added that dial-peer, any calls that consist of more than 7 digits (ie; a long distance or 1-800 call) automatically get picked up by the 7 digit dial-peer. Therefore, the rest of the 10 or 11 digit number never gets completed. Is there a better way or different way of doing this? Any help is appreciated. Below is a copy of my dial-peers.

You cannot have both 7 and 10 digits DPs, because these perfectly overlap.

And relying on  timeout after 7th digit, as tie breaker is not a good idea.

This being said, destination-pattern for 7 digits should be [2-9]......

[Robert Craig]

So should I remove the 10 digit DP and stick with a 7 digit and a 11 digit? At the same time, adjust the 7 digit to only include 2-9 for the first number?

[paolo bevilacqua]

Correct. And hopefully your extensions all start with 0 or 1.

[Robert Craig]

Ooops, actually my extensions are 5xxx. How do I encompass that into the destination pattern?

[paolo bevilacqua]

What happens is that you will be unable to dial 7 digits local numbers that begin same as an extenstion. But you can call them 1+10 likely.

OK, so I made the changes you suggested earlier and I removed the 10 digit DP. Now, one of my extensions is 5002. I just dialed it and it worked great. I also dialed a local number that began with 5 and it went through. My understanding is that if the number doesn't match an internal dial peer (ie; an extension in the system) it will go through the next logical dial peer that encompasses the amount of digits dialed?

Yes, only complete overlaps do cause problems.

Thanks for the nice rating and good luck!

Thank you!
