-----------------------------------------

I hate to bring up a old subject but FreePBX has been trying to integrate the different GSM cards that are on the market and its creating alot of issues.  Each manufacture is doing it their own way and it actually is worse when trying to patch for these changes.  OpenVox has it done one way and Sangoma does it another way but they conflict with each other so you can not allow both patches in the same asterisk/dahdi version.

I would ask that this be reconsidered again as Asterisk needs a standard for GSM cards and I thought one of the reasons for the change from zaptel to dahdi was to allow for better integration of any type of cards into asterisk/dahdi.

I guess I am asking what the official stance is on this and why it is being rejected.  This seems like a pretty simple request and would make all of our lives easier when trying to deal with the ever growing popularity of GSM cards.

I see reference the postion was stated in a email.  Can we get this postion stated openly in this ticket to allow us to make a better argument or decision on how to move forward.

> Hello Asterisk developers,
> There are multiple GSM cards that can be used with Asterisk out there, but currently each vendor is using their own channel drivers (mostly based on chan_dahdi). With the release of our GSM cards, Sangoma Technologies has developed an AT commands library to support GSM modules, called LibWAT (Wireless AT).
> Just like LibPRI and LibSS7, LibWAT uses DAHDI interface to talk to the kernel drivers. It is completely open-source, and our ultimate goal is to make it the de-facto GSM library for Asterisk. 
> LibWAT is designed to work with any GSM modules. In addition to the GSM 7.07 spec, LibWAT also has provision for vendor specific AT commands. Even though we have only tested with Telit GSM modules so far, we encourage anyone willing to participate with the LibWAT project to test LibWAT with their GSM module of choice so we can support as many GSM modules as possible.
> LibWAT is available on GitHub. The main development branch can be downloaded using git:
> git clone git://github.com/sangoma-dev/libwat.git
> Instructions on how to configure LibWAT with Sangoma cards can be found here:
> http://wiki.sangoma.com/wanpipe-linux-asterisk-gsm#dahdi-install
> I posted the changes required to chan_dahdi.c below:
> ftp://ftp.sangoma.com/linux/custom/DavidYS/asterisk.libwat.patch (tested against SVN rev:359905)
> Suggestions and comments are welcome.
> PS: I was not able to login on the reviewboard.asterisk.org with my JIRA credentials, can someone tell me how I can get an account to post on reviewboard.asterisk.org. Thanks
