I'm not able to find shared lines and how they will help me by looking at these docs.
Can you give me a little more guidance on what page number on each doc you attached?
In the first doc I cannot find shared lines ..they reference it sort of for octal lines. But the 524SG handset doens't support that so that won't work.
The other two docs are good, but I don't see how they help my question at all.
I'm not even sure the customer wants a shared line anyway- he wants the cofnerence room phone to be a conference room phone until he logs in. and when he logs outs, it goes back to being just a cofnerence room phone.
So he has to be an extension mobility user...but can he be both - have his user, extension, DID as the first button on his desk phone, his remote phone AND then login to a EM enabled phone?
