Are you referring to call pickup groups? ring groups? or some other group definition. Regardless of the answer there is no GUI support for what you’re looking for.
is there a way to change the extension CID in a batch?
But setting the outbound caller ID based on what ring group or queue the extension is a member of would solve the problem for some situations. Is there a way to do that?
Thanks for the Bulk Handler tip @Igaetz. That looks like a way to work around what I need until I can find a plug in that will set it based on the actual group membership. I’ll give that a try.
If your CID is fairly static, I would think setting at the extension level would work the best. If not static, the commercial Caller ID Management module would prob fit the bill: https://wiki.freepbx.org/display/FPG/Caller+ID+Management
