I am using it personally. I am in the first step setting up The system with Ubuntu 12.04 Server. I tried with CentOS. I work ussually with this distro, but i could not make it work because of my lack of understaning this gsmopen system. Yesterday i made it work with this: Ubuntu 12.04 Server AMD64 Huawey E169 Install all the Libs i found in the freeswitch wiki (all) I set up for the time been just only one dongle. ttyUSB1, ttyUSB2 Codec: G711 I made this dialplan: <extension name="dongle"> <condition field="network_addr" expression="xxx.xxx.xxx.xxx"/> <condition field="destination_number" expression="^34(\d+)$"> /* Because Spain Mobile */ <action application="set" data="continue_on_fail=yes"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="sip_ignore_remote_cause=true"/> <action application="set" data="proxy_media=true"/> <action application="bridge" data="gsmopen/gsm01/$1"/> /* Default config i have, changing just only tty ports */ <action application="hangup" data="NORMAL_CIRCUIT_CONGESTION"/> </condition> </extension> My Experience: Calling with G711: no delay, audio quality same like with your own mobile (perfect), even with network operator low coverage were i am. Calling with G729: little delay (sensible). Probably i had the system not very well implemented. A very important thing we did: We try unlocking the dongle. We did it. With every system we test, no working. We soldered pinouts to a unlocking device. Reinstall complete firmware with this device. Then from this factory firmware we unlock it and activate the voice. I am experiencing with it. In my opinion for the time been works very nice. I need to stress the system with 8 dongles and live traffic to check all the issues that can happend. During this week i will do so many test. i will give you feed back.

I've been testing out Gsmopen with an E160. Do you have any experience with that one and why do you prefer E169s? I personally have not. They were, however, recommended to me by a friend who has experience with Huawei-brand dongles. I'm in NYC. I might be interested in a group buy, but I'm still trying to figure out if it's going to reliable for clients. I currently cannot verify anything about the Huawei devices. The group buy actually fell through, and I was planning on getting one or two to play with. If others are interested in doing a group buy I'd be more than happy to facilitate. In your setup, what is your general purpose for having them in production? I planned on using a few for emergency backup in case the Internet or something else went kaput. With the advent of cell phones these days, it's really not an issue now. Otherwise, to me it's a toy. Now if you we're in Europe, there are advantages to using gsmopen and a dongle with a few different mobile providers to get free or reduced rate calling (within the same network). I'm CC'ing the Freeswitch users mailing list, in hopes that someone can better answer your questions. If you haven't already, subscribe to the ML by going to http://lists.freeswitch.org/mailman/listinfo/freeswitch-users. Good luck in your future endeavors, and welcome to the wonderful world of Freeswitch.
