[Asterisk-Users] Small office with all employee's offsite

Tue Nov 29 12:31:36 MST 2005

I am using this dialplan with DID's to great effect, I have 130 guys doing
exactly what was discussed here. After 12 seconds ringing their SIP or IAX
client, the dialplan calls the cell automatically, during working hours. If
they don't pick up after 18 seconds, voicemail.  After hours, both phones
are dialed concurrently. Also, fax detection is automatic so DID is desk
phone, cell phone, and fax. 

Using it this way completely obviates the need for call forwarding; I find
CF more of a hassle than it's worth because people are dumb and forget that
calls are CF'd then complain that their phone isn't working. 

Note voicemail box is the same as last 4 digits of DID. This simplifies
enduser training. 

Permission given to steal this dialplan logic outright if you can put up
with my sloppy code.

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.

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.
