Is there a way when extension 100 uses Trunk A, it sends its Outbound Caller ID defined in the extension which might be 2135551212, and when it calls 200, on Trunk B, it sends its extension number (100) as the outbound Caller ID?
In Outbound Routing, that’s exactly what the Intra-Company checkbox is for.
I had just found it seconds after you posted it.
Thanks
