TEHO or Calling over WAN

Question

Hello ,
I need your advice on what to do to make this work please.
I am having problem in translation-rule on CME, I have 4 VOIP Dial-peers to remote branche office, the other three Brache office are fine
but the fourth one has the same extension as Frankfur (Main - Office).
Berlin-CME has 201 - 210 Extension number, while Frankfurt-CME has 2001 - 2040 Extension Number.
When I applied destination-pattern 2../(20X) on Berlin Dial-Peer, I can call to Berlin Branch office, but i can not make call to Frankfurt Via WAN with (20XX) / 2...
When I removed 2.. on Berlin Dial-peer and created tranlation Rule 7 for Berlin on Main office CME.
The translation-rule test  works fine as it shows on MAIN-OFFICE_CME, but i can not make calls to Berlin Extension , but can call with DID number 792623.. via WAN, but 2.. is not work
I can call if i use DID number 792623..

Answer 1

Hello all,
Here is the solution;
Creat Steering code ( like Prefix) or you will have to use the T for
overlapping dial plans.
(A)
dial-peer voice 200 voip
destination-pattern 2..T
session target ipv4:10.10.X.2
=====and==
(B)
dial-peer voice 2000 voip
destination-pattern 2...
session target ipv4: 10.20.Y.2
You can press # so you don't have to wait 10 seconds, but you will
either create a steering code or wait 10 seconds.
