Celliax is a GPL channel driver for Asterisk, chan_celliax, development and download site http://www.celliax.org
  • runs on Windows and Linux
  • manages GSM and CDMA cellular phones through an adapter, composed by a serial datacable (for commands) and an audiocable (for the voice) interfacing the computer soundcard
  • Celliax is also capable of making and receiving Skype calls through the cellphone, and has an app like app_directory that let you choose which one of your Skype contacts you want to call.
  • on Linux Celliax can also manage ALSA voicemodems (whithout Skype support)
  • on Windows and Linux (and *BSD) manages virtually all kind of cellular phones, both old Nokia models (with proprietary Nokia FBUS2 commands) and cellphones supporting AT commands (also with Motorola extensions)
  • with Celliax is distributed the Celliax LiveCD, with a working installation of Asterisk, chan_celliax, and configuration utilities, based on Knoppix. The Celliax LiveCD contains also all is needed to run Celliax on Windows: the cygwin installer and the tgz with the asterisk-celliax stuff to be untarred in a basic cygwin installation.
  • Headless Celliax, cellphones, Asterisk and Skype (without X)! Booting the LiveCD in console mode you find a script (/usr/local/asterisk/usr/sbin/celliax_server) that automatically launch Xvfb (the fake X11 server), Skype and Celliax. Also via ssh! Isn't that cute?

Details

Some notes on connecting asterisk to the cellular network. Why?
  • Leverage free mobile to mobile calling to lower costs. (nice picture)
  • SMS gateway (See note). An easy way to send SMS messages to mobiles from Asterisk is to use the FASTSMS command or the SMSx command.
  • Mobile applications; geo-location tracking or theft prevention for example
  • Remote monitoring
  • Mobile Machine to Mobile Machine so called M2M

The cellular capable device you attach might be.
  • A regular cell phone
    • Via some home brew adaptor
      • USB, Bluetooth, etc
      • Analog patch cables to sound card
    • Via some commercial cell to traditional phone adaptor
      • Note that one of these has a serial line controller option
  • A PCMIA cellular card
    • More home brew to get the analog connection
  • A "Fixed Cellular Terminal" - i.e. a device intended for this.
  • A PCI wildcard with GSM modules, with proper software

Interesting notes in the asterisk mailing lists.

Vendor
Details regarding Serria Aircard as possible bridge.

PCI Cards with a GSM interface
  • Voismart - Voismart vGSM with up to 4 GSM channels PCI card, made for Asterisk and linux in general. See also VoiSmartGSM for instructions and GPL drivers
  • Junghanns - uno/duo/quad GSM PCI. Works with Linux

333Re: Huawei Fixed Wireless Terminal

by sqats, Wednesday 13 of June, 2007 [09:21:02 UTC]
Hello There.
I am using a similar device but I can't seem to get it to work. I am using a CDMA Hauweii ETS 1201 Black Box (FWT).
I have asterisk configured and its working internally. I have a digium tdm400P card with one FXO and one FXS.
When I connect my Black Box to asterisk and call the CDMA number, the call is routed to an extension as configured. However, when I pick up the extension, the call does not initiate. I am calling from my mobile phone, so on my mobile, it keeps ringing. Its as if I've not picked up. Finally the mobile phone says "no answer".
Even when I have an IVR pick up the incoming call, I see asterisk going through the IVR script but then, my mobile phone is still ringing!
Is your FWT box working? If so, how did you configure yours? Are there any special settings I need?
PLEASE HELP!!!
