In searching for Caller ID programming on a Cisco CME, I came across the station-id command for FXO, FXS and DID ports.
Since we are not subscribing to our Telco providers incoming call display, this command allows us to assign a name (or number) to calls coming in on the voice-ports.
If we were using the Telco's call display, we would need to use the ephone-dn forwarding setup in the previously mentioned post.
station-id name Line 501
station-id name Line 508
Since we can't call out on a DID port, the station-id helps us report troubles to our Telco provider.
The station-id number command would assign a E164 number to that port. However, some people might get confused and think that is the number of the person calling.
We using the FXS port for paging, so we simply call it "Paging".
station-id name Paging
