We're not doing a hotdesk. The phone, in this case, is always extension 246. The names aren't really important as well as they are just labels on the buttons.

Basically, I have in buttons.cfg pertaining to this extension:

[SIP/246]
type=extension
extension=246
context=from-internal
label=Brandon Roop

[SIP/246]
type=extension
extension=246
context=from-internal
label=INCTX Shipping
mailbox=246@default

[SIP/246]
type=extension
extension=246
context=from-internal
label=Pedro Garcia

[SIP/229]
type=extension
extension=229
context=from-internal
label=Quinton Nester

I included another extension 229 in for reference. What I'm seeing is that with this setup, the last entry for 246 is the only one that shows in use. So, for example, if someone dials extension 246 (SIP/246), the first 2 buttons show no activity, only the last button (the one labelled Pedro).

This is using plain vanilla Asterisk.

Any ideas?

I have a situation where we have several people that use the same phone. One example is a warehouse with multiple people in it and one phone. I thought it would make things easier by creating a separate button for each person, so say extension 246 would have Jim, Bob, and Harry. The reasoning behind this is that when a call comes in, the receptionist can just look for the person's name instead of having to know Jim is in the warehouse.

That part works.

The problem that I'm seeing is that when someone is on this extension, say Bob, it only shows Jim in use. It looks like it is only showing the last button registered to the extension as being in use. Am I doing something wrong, is that just the way it is, or what?

I've got one use case for having Cust1 visible in the tabs. Using a Digium phone with DPMA, there is a button to record your phone calls. If you happen to use that instead of FOP2 to record a call, the phone drops it in Cust1. You can play it using the voicemail app on the phone, but you can't really do anything with it. If it was available in the Voicemail App in FOP2, then users would be able to download the file and store or email it.

This particular customer was just converted over to pure Asterisk from Switchvox, and surprisingly, Switchvox wouldn't let us download those recordings either. We actually had to play the recording back over the speaker and record it with a cell phone. With Switchvox, you can't get to anything, much less the underlying operation system. Worst. Mistake. Ever. recommending that closed up, locked up, system.
