Dial 2001 from 3002(sccp) - digit-by-digit or enblock(with #, call) - same result: always dial-peer 15.
It is logical to me: 1000 variants better than T, but... For enblock it knows the length, so both dial-peers looks the same.
1) Does the command "show dialplan number" work as enblock?
2) Why my case the active call is used dial-peer 15, but by the command the preferable is dial-peer 5?

Please clarify a little bit the situation, thank you in advance.
P.S. dial-peer hunt 0

Dmitry,

Dial peer matching will choose the longest explicit match. In each case dial peer 15 is the longest match. The "show dialplan number" command is showing you a list of possible dial peers, not necessarily in order of preference.

Hello Brandon, everyone,

Thank you very much for your comment.

I have checked the situation again and I was wrong - both dial-peers are used.

Now I have other questions, but it will be not correct to keep it under this discussion.

So I am going to open a new discussion about the selection of outgoing dial-peer. Anyway thank you for you message.
