Hello FreeSWITCHers,

the new version of GSMopen is basically usable, and the docs at the
wiki almost up to date (barring the details of the config file, you
don't need them now :) ).

Good news is that GSMopen now supports Huawei E1550 and compatible
dongles, that are cheap (roughly $20 on Ebay) and reliable.

Thanks to dongle's pcm serial streaming via USB, no more need for
sound hacks, ALSA, or any sound subsystem (and cpu load). All is

It's reasonable to expect to be able to support many dozen concurrent
calls per machine (dongles are USB 2.0 compliant).

Works well right now on Linux and Windows, and would probably works on
*BSD and OSX with minor tweaks.

Code will be polished, refactured, rewritten, etc. But the thing is there.

So, please update your source code to latest git, have a look at the
wiki page, build mod_gsmopen, connect a dongle to your machine, and
begin catching bugs and documentation inaccuracies. And asking for
features for your use cases.

Thanks to you all in advance, it's a pleasure and an honor to be part
of this community.
