I want to prevent extensions from calling numbers that exist on the phone system and thus using up two SIP trunk channels where none are needed.
For instance, I have a conference bridge DID that OUTSIDE callers are supposed to use, and INTERNAL callers should be calling the conference bridge extension. Instead, they are calling the DID and using up multiple trunk channels.
Is there a way to reroute that specific DID to the conference bridge extension instead of the trunk?
I’ve looked through the forums and can’t find anything on this, but I could have missed something.
Thanks for any ideas.
