We have both same ip addressing iptel network in 2 company but different did numbering . Company A with 111XXXX and company B with 222XXXX. Any one have any idea how to create an extension number for both company to communicate?
Re: an extension number for internal communication
You can set everyone up on a 4 digit dialing plan since you have non-overlapping DIDs. Then setup a Translation pattern for each side.
Company A's DID are 444-2000-2999
Company B's DID are 444-3000-3999
In Company's A CCM, setup a Translation Pattern for 3xxx ---->94443xxx So when company A dials 3xxx, it automatically prepends the 3xxx with the outside line and the local exchange to the DID. It creates the "sense" of a 4 digit extensions between two seperate sites.
In Company's B CCM, do the same Translation pattern, but setup 2xxx ----->94442xxx This should help you create one number then.
