I know that users can create their own messages but I can’t see how to change the extension number. Here is my scenario.

Users extensions can be any string. Sometimes it is an actual phone number but often it is their user ID. Let’s say that two of them are foo and foo3.

I also provide virtual PBX extensions that accept an extension and direct the call to a device. A phone can be in more than one PBX so calling 4155551111 might assign extension 200 to foo and 201 to foo3. Calling 4165552222 might assign 210 to foo and 220 to foo3.

All of this works great until a call goes to voice mail. Now the foo extension says “The person at extension is not available”… The message for foo3, which might be extension 201 or 220
in the above example depending on which PBX was called will say “The person at extension 3 is not available…”

So my question is this. Is there some way in the dialplan to set the number that is used for that message? Is there a variable that can be set before doing a GoTo to foo or foo3?

Thanks.
