[Asterisk-Users] Able to tell if phone is registered?

[Tim Pushor]

Hi All,

I have a new asterisk setup running at home and am very happy with it. 
One thing that I am trying to do is to take various actions in the 
dialplan *if* a particular phone is registered/authenticated/connected. 
For example, if someone dials *me* and is shows that I am connected via 
my softphone, to try it instead of my deskphone (and possibly notifiy 
the user in advance that it is taking that action).

I didn't see any way to do this using the standard applications - would 
someone be able to point me in the right direction?

Thanks!
Tim
