OK, then this is easy. Instal Asterisk in the central location, along
with a Sipura SPA-3000. Configure that unit to answer the incoming
POTS line and act as a VOIP gateway for Asterisk. Then configure two
additional SPA-3000 units, one at each employee's location. Then,
configure Asterisk (I recommend [EMAIL PROTECTED] for your setup, BTW) to
route the incoming call to the right extension based on time of day,
auto-attendant, whatever. The SPA-3000 units at each remote site will
also be able to accept the employee's incoming POTS line and pass that
call through to the phone they normally use without resorting to
sending it to the Asterisk server and back. (It's all in the SPA-3000
setup.
Very cool indeed. Thanks Tom! Now to throw a monkey-wrench into the
works... One of the employees spends a lot of time outside of his home
office, and is then reachable only by cell phone. But we (for obvious
reasons) don't want to hand out his cell number to everyone who wants to
reach him. So, he will often forward his home phone to his cell, and
forward the main office number to his home number (so when people call
the office, they get his cell without realizing it).
We do this all the time. We just moved and have three people working
from their homes. The boss's extension rings here locally on a spare
phone and rings his IAX2 phone at home. He also forwards his extension
to his cellphone when he is out using *72 on the Asterisk box. One
employee is working from out of state and his extension calls his
cellphone. When someone dials his DID number it dials back out to his
cell phone and no one knows any different. When we dial his three digit
extension here it goes to his cell phone. The last person has an IAX
client running on his laptop and takes calls from there. When someone
calls in and presses '2' for support it rings a guy out in production
and the other person working from home.
I have my extension set to ring my Grandstream phone and my cell phone
at the same time and I can take the calls from anywhere. I can even
transfer a call back to another extension from my cellphone if they need
someone else. Asterisk does all the call forwarding and phone routing.

Is there any way to use the SPA-3000 at his house to re-route calls
(VOIP calls, in this case) to his cell? Or would that have to be done
at the office where the server is physically. I'm not clear on whether
the Asterisk server can control a remote SPA-3000 in this way.
As long as Asterisk has a way to re-dial out a phone line or voip
provider, it can route an extension anywhere and the caller will not
know it.
I guess this could be done directly from the Asterisk server, couldn't
it? It wouldn't be something that could happen automatically; it would
have to be manually turned on and off. But it would also require
another POTS line at the main office for the outbound call -- so I'd
rather leverage the phone line at his home office to make the outgoing
call to his cell phone if at all possible...
One more monkey-wrench -- what if I want both of the employees to be on
the phone at the same time? Two incoming POTS lines, and two SPA-3000's
at the office? Or does it make more sense at that time to get a TDMxx
card?
This will not change, you're still looking at three lines in the
scenario I outlined above. (Unless you switch to incoming VOIP, but I
do *NOT* recommend that.)
Nope, I don't believe in VOIP replacing POTS completely yet. Maybe in 5
years...
