Yep, this is the kind of thing I am after, except my hardware PBX has 
limited connectivity and ideally I want a USB or ethernet hookup to the 
box..?

The scenario is basically a small commercial PBX (small form factor) 
which can be supplied with IP phones and will talk out via a cell phone 
channel (or via a satellite phone if that's the only option available, 
but this is out of scope of this question).  So basically I want to 
figure out some options to hookup a GSM cellphone channel to a small 
form factor asterisk PBX which has limited expansion options (ethernet, 
USB and mini-PCI - although prefer to use the later for a wifi card...)

I only need a single channel of GSM right now (and a single SIM)

Any thoughts?  Remember this needs to be production quality and priced 
sensible for a commodity market

Thanks for pointers to hardware
