[Asterisk-Users] virtual extension per user ?

[Alex Ongena]

Hi,

People here often work on 2-3 places (office 1, office 2 and home).

I would like to give them 1 extension (XXX) and to ask them to
'register' the phone they use at a certain moment.

The idea is that, when you need someone, just dial XXX and the
phone near him (in Office 1, Office 2 or at Home), will ring.
This will keep my queue system and other tricks intact, where I
always use the single extension XXX.

I know you can 'forward' calls to other extensions, but when people
go from Office 1 to Office 2, they forget to enable their forward in
Office 1 to Office 2.
I like a solution where they can say 'Please register me, I'am now
sitting in Office 2'. The moment after 'registration', when you call
XXX, the phone in Office 2 will ring.

In all places I use Asterisk 1.2.1 with bristuff, Cisco 7940/60 phones
with Sip and some Sip softphones.

Any hints or tricks to get this behaviour ?

Thanks
Alex
