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 digital. 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. http://wiki.freeswitch.org/wiki/Gsmopen -giovanni -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618
