[Asterisk-Users] Two Phones - Same extension?

[Mike McMullen]

Hi All,

I have an employee who works mostly in our office but
maybe once or twice a week has to work from home to help
care for her special needs child.

As background we have AAH 2.0 running with 8 analog lines
connected to two digium t400P cards. We have 10 sipura-841s
as handsets in the office.

I would like the employee to be able to make and take calls
from her house when the she has to work from home. I'm leaning
towards just installing s/w on her laptop with a headset for that
setup.

My question is how to handle setting her up so that she only has one
extension shared between the office phone and her laptop. For this
to work, do I need to unplug her phone from power/network in
the office when she is at home or, hopefully, is there some other
magic that can happen?

TIA,

Mike
