Add origination extension to view of AI Agents to allow returning callers back to the source

[accentlogic]

Please add the origination extension to the view of AI agents. This would also be very useful for sending a caller back to the User, Digital Receptionist, Call Script, Ring Group, or Queue that sent the caller to the AI Agent, and the call did not arrive directly via a DID or Trunk.

Additionally, the agent should be able to send the call to the Voicemail of the originating extension if the situation warrants and is allowed.
