UC520 - Display free lines on phones?

Unanswered Question

Hello, I have a UC520 with 2 analog lines going in and about 10 users with 7941s and 7912s. On their old PBX system they had 2 little red lights on each phone that lit-up whenever a line was busy.

Now, there doesnt seem to be a way to display if their two outgoing lines are busy... SO the only way to find out is by dialing 9-xxx-555-xxxx and then hearing a busy tone and trying a bit later when there's a free line...

Any possible way to display the 2 free lines on a 7941 screen or maybe a service someone created to see when the 2 analog lines are busy?

I think the best option would be to tell the customer to buy a 3rd or 4th line for an extra 30$/month, but they just want me to double-check.

Hi, in the admin guide , check "trunk" command under ephone-dn, with the option to monitor FXO port. Note, when you configure like that, all calls made from that DN will have trunk digits prepended to dialed digits, the consequence is that you need to configure additional button for internal calls. In summary, is up to you to try first, show to customer, and find a configuration that they like.

Hope this helps, please rate post if it does!

I know, it's large book. Try the way I do, download .pdf and use the search function. It's there, you just have to locate it.
