Quick Dial Peer Question...

Unanswered Question
Feb 16th, 2007

I am setting up a VOIP dial peer. I have 6 destination patterns that should all be exiting out the same interface.

Should I create 6 separate dial peers? , or,

Should I place 6 distinct "destination-pattern" statements in the same dial peer?

Thanks very much for your help everyone.

I have this problem too.

u can have only 1 destination-pattern. You will need 6 different dial-peers.

Thank you for your help and clarification MChandak. I will go ahead and do that.

If your destinations are related, you may be able to combine. If your destinations were 3100, 3200 and 3300, you could use "destination-pattern 3[123]00, for example.

Hope this helps. If so, please rate the post.

thanks bbuffin...actually they are all toll free numbers that are being passed through soe 800, 866, 888, etc. Would you suggest doing something like 8[068][068]...... or would that be a security issue as it opens up a wider # of phone numbers to be transferred across the ipl? thanks

You'll want to make the scope of the dial peer as narrow as possible, so if you only want toll free numbers using this path, then I would recommend using dial peers specific to these numbers. Using a pattern like 8[068][068]....... would allow a number such as 8061234567 to route using this dial peer which is probably undesirable.

Good point there Brandon, thanks. If I want to, say, permit all of the following:

8001......

8002......

8003......

8008......

would the following pattern be of use 800[1-38]...... ?

Thanks again

excellent, thanks very much.

Some of the DIDs are in a range, so it makes this much easier. However, some of them are just completely distinct phone numbers. In your experience, should I just inividually set up destination patterns for each number.

Thanks again

I would use the range where you can to cut down on administration and the size of your configuration. Dial peers do add to the size of your configuration and therefore, the amount of memory taken up on the router.
