Anyone know how to use an Android phone as a GSM gateway with Asterisk?

[arjunsdarkside]

I'd like to be able to make calls from my Asterisk PBX through my Android Phone. Anyone know how to set up the interface? I'm using an HTC G-2

I'm also looking at a way for doing just this.

Currently I have the following set up.

Asterisk Server on my LAN is up and running.

All phone clients can call each other (Calls can be made between any of the phones - sipdroid can call the 7910s etc).

This is mostly a playground, so there are no external telephony connections (Either through a land-line, or via commercial VOIP providers). However the HTC desire obviously has a GSM/Mobile connection.

Two things I'd like to achieve:

[1] I'd like to be able to get this up and running so that I can dial a UK phone number on my 7910, it would then be routed via the Android phone (which is connected to Asterisk by SIP) onto the GSM network to make the call.

[2] Similarly (this may be easier to set up) I would like to have it so that incoming calls on my Android phone can be routed via SIP to one of the 7910 desk phones.


I've hit a brick wall with this one, so if anyone could offer advice it would be appreciated. I've had a look at the SIPDroid configuration, but this doesn't seem to have any options for routing calls.

In theory: objective [1] would actually require an Andorid App which works as a SIP-GSM gateway to forward on outgoing calls. Objective [2] surely should only be a case of finding an andorid dialer which can redirect incoming calls on GSM to a SIP account which is already configured on the phone. A basic case of call forwarding surely?


As I say, I'm stumped at this point. IF anyone can point me in the right direction I would happily test and document this.

I don't think you can do this. About the only way I can think of is to write a custom app, and a custom channel driver for Asterisk.

You might be able to route audio and tones through the ADB bridge, but I'm not confident it would be possible.
