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.
