Trying to configure one phone with 2 CLI's

[future10]

When client wants to make a call to another country they want to have that country's CLI to come up so the recipient will not have to call the International "home" country.

At present the SIP account has a number of numbers and we can either set an Outbound rule when the user dials for example 0044 then the CLI gets shown as 0044xxx

The handsets are on Yealink 20p through to t46g

Any advice would be wonderful

As an extension, you can set the outbound CID, which, in most cases overrides, the CID assigned to the trunk itself. So, for one phone to change caller ID, you have to either route the call over a different trunk group, using outbound rules, displaying the number assigned to that outgoing trunk, or, place the call from a second (or third, or fourth) extension key, on the set, that has a different outgoing caller ID datafilled, in that extensions settings.

It would appear that a feature, to make this easer to accomplish, is in the works....
