[Asterisk-Users] Forwarding To Cell Phones with Asterrisk PBX

[Colin Anderson]

Yeah, I have it in my dialplan and use it heavily. Just make another Dial()
command to the cellphone the next priority in the dialplan underneath the
Dial() statement for your extension. For example:
 
Extension is: 12345
SIP extension is: SIP/12345
Cell number is: 555-1212
 
in Extensions.conf:
 
[myphonecontext]
 
exten => 12345,1,Dial(SIP/12345,40) 'Dial extension 12345 for 40 seconds. If
no one picks up then...
exten => 12345,2,Dial(ZAP/g0/5551212,25) 'Forward the call out to the user's
cell. Once they pick up, a native bridge of ZAP channels occur and Asterisk
is out 'of the media stream
exten => 12345,3,(anything else that happens later, like go to voicemail,
etc)
 
It's important to time how long it takes for the remote user's cellphone to
pick up for voicemail. If the user's voicemail on the cell kicks in after,
say 4 rings, time your second Dial() command to be just short of that,
otherwise the remote caller will get the cell phone's voicemail, which is
probably not the desired behavior. In my case, I set it for 25 seconds, as
our cells' voicemail kicks in after 30 seconds. If there's no call pickup on
the cell, call processing continues to the next priority, which is voicemail
or IVR depending on what number they called. 
 
Also note that once the native bridging happens, you are using two lines, 1
inbound to Asterisk, and 1 outbound from Asterisk to the cell phone. Line
capacity becomes an issue unless you have lots of channels, like a PRI, or
if your useage is light, like no more than 1/2 of your total Zap channels
could be inbound and forwarded to your remote user's cells at any one point
in time.

Hello,
 
My company has a 800 number that we use for customer service.  However,
instead of having our customer service reps at the office, we route these
calls to their cell phones using a service provided by gosolo.com.  However
our current system isn't ideal because it will call each number in order
causing longer and longer waits when we've got people on the line.   Our
goal is to set up a system that allows us to design the way calls into an
800 number are routed out to our cell phones.
 
I've been reading about Asterisk and VoIP to see if we can better this
process by having all the reps called at once, and whichever person answers
first handles the call.  It looks like this may be possible with the dial
command (http://www.voip-info.org/wiki-Asterisk+cmd+DIal)   However, would
we be able to forward incoming calls to cellular phones?  The wiki reference
for the dial command talks about using channels and the list of possible
channels doesn't seem to have an option for cell phones.  
 
Additionally, I've looked at
http://www.voip-info.org/tiki-index.php?page=Asterisk%20Connecting%20to%20th
e%20Cellular%20Network to see how to connect Asterisk to a cellular network.
However it looks to me like this is a method to take a call placed to a cell
phone and route it so that other home phones could be used instead.  Is
there a method to go the other way around and take a call placed to a land
line and route it to the cell phone?
 
Thanks,
Theo
