First off, i am really new to VoIP setups on Cisco devices.
So, I managed to figure out a way to set a specific user's extension to be reach from an external called, on a specific DID. So, if i called this guy from wherever, outside his office, at his number of XXXXXXXXXX, it translates to his internal extension just fine, and rings his phone.
What I am having trouble with now is when he wants to call outbound. He wants his DID to show up in the caller ID of whomever he is calling. Currently, it displays the office's main phone number instead, in the caller ID of whomever he calls. I am at a loss on how to make this work unfortunately. Here is some of the relevant config that is currently in place. If anyone can assist, that would be great.
