UC500 Show incoming FXO line on phone?

Unanswered Question

I have a UC520, setup in PBX mode, with 3 incoming FXO lines. The staff needs to answer the phone differently depending on which line the call is coming in on.

I know that i can setup a DN for each line, and PLAR each port to it's corresponding DN. Then i would have to map a button on each phone to each DN. I am wondering if there is a better way. The lines do not need to have their own buttons, i just need the phone to display which line the call is coming in on. Is there any way to do this?

As I am writing this, I just had a thought. What if i configure the DNs and PLARs as above, but then setup each DN as an overlay on top of the user's extension. If it is PLARed to one of those DNs, i believe the incoming call shows which DN in the overlay it is calling across the bottom of the phones. I will try that.

Also, if i do setup buttons for each line, is there an easy way to map a phone button to a perticular FXO port? i.e. user picks up phone, hits 'line 2', and is guaranteed to use the outgoing FXO line 2? I believe I cannot use traditional FXO trunking because I can't configure in key system mode. But maybe there is some kind of hybrid config that would allow me to do this?

For the first part regarding the different FXO lines, refer to this document link:


I think this is what you are looking for to conserve buttons.

For the second part you can actually force an ephone-dn (which corresponds basically to an extension) to only use certain FXO lines by configuring COR lists via CLI.  For more information on COR, you can refer to this webcast at around minute 28.
