I would like to be able to use these numbers as called id when making calls. Is it possible to use the first number when prefixing it with a 0 (zero) and the second when prefixing with a 1?
Set up two outbound routes. Use one if you prefix with ‘0’ and the other if you prefix with ‘1’. Set each route’s CID with the appropriate Caller ID settings. Send them both to your outbound trunk and don’t set the caller ID in the trunk.
The outbound trunk might be another way to do this - basically the same setup, just set the outbound CID in the trunks and route your outbound routes to the specific trunks.
It kind of depends on how your VOIP connections are set up.
Sorry but I don’t quite understand. Currently I have 1 outbound route setup, ofcourse I can create a second one, but how do I set this up to use the prefix?
Second option: how to I “tell” the phone which trunk to use?
