Hi, Today my voice network works with dial-peers point to point using gateway cisco, This network is for two companies A and B, between company A dial direct ext to ext for each place, but for company B need to dial a code and the the extension, for dial the place C we use 835 recibe a tone from the PBX and dial ext of 4 digits, Now we try to implement a GK, It's easy to add the gateway of company a because his dial plan is a 4 digits and prefixes int the GK are easy to configurate, but we don't know how configurate codes for company B in the GK, Dou you how to enable this, the idea is to get rid off this codes and dial directly, but we have a issue in our dial-plan, is repeted in some places of company a and B.

thansk and best regard
