Fast response in dial-peer

Question

I have a dial-peer match the string 10 and another matching string 100.
everytime I dial 100 it matches the dial-peer for 10 and rings before i even complete the dial.
is there anyway i can let the router wait to collect all digits before matching with a dial-peer?
PLS HELP!!!

Routers do not have the ability to see if a longer destination pattern will also match. As soon as the router finds a dialpeer that matches, the call is routed to the session target or port.
There are a couple ways to deal with this.
1) Have the shorter number a different first digit, e.i. 20, so that it does not match before the 100 pattern.
2) Make both patterns three digits long and make each unique.
3) Depending on your needs, you might be able to use the "T" to make the 10 pattern to wait for the length of the inter-digit timeout. This would mean that anyone dialing 10 will wait 10 seconds or so before the call routes.
A useful command for checking which dial peer the router will use is "Show Dialplan number XXX" XXX is the number that is being dialed.
Hope this helps.
