I have spent countless hours trying to make a UC540 work like our client's old basic key system, and still have not found the right approach. Here are the requirements:
1. When placing an outgoing call, picking up the handset should sieze an outgoing line and the user can dial without dialing "9" first. The button for the line in use should light up on all phones.
2. The user needs to be able to place a call on hold and pick it up from any other location.
Here are the problems I have encountered:
1. With the incoming lines set up as shared lines, it works fine for incoming calls: the Line button lights up, and when you put the call on hold, the line button flashes and can be picked up at any extension. With outgoing calls though, only the extension light lights up, and if you put a call on hold, only that extension flashes - it's impossible to get the call on a different phone.
2. I have tried a version using call parking, but it was too confusing for the client (an auto repair shop).
We can probably get them to be OK with dialing "9" first, but the ability to put a call on hold and retrieve it anywhere easily is key.
Any ideas on how to make this easy to use? I feel like I am missing something obvious.
Here are the vitals of the install:
4 incoming CO lines
7 phones, all SPA509G
4 buttons on each phone are dedicated to the FXO lines (Line1, Line2 etc)
Auto Attendant and Voicemail needed.
Aside: The UC320 actually seems to handle this better because you can park/unpark a call by pushing a button dedicated to a park slot. With this I could set up 4 park slots and that would solve the problem. On the 540 (as far as I can tell) you can't park a call on a specific button.
