<br><br>I kind of like the idea of 2n's stargate but when i read the
manual (the one available for download), there were a lot of
complicated issues in configuring the device, (i mean, you have to like
set jumbers on the m/board,etc) and there was a clause that said that
callc could only be routed form the gsm module to the primary pri card,
i.e its a one way traffic from voip to gsm. Although, i wouldnt know if
they have upgraded that perticular manual, but according to what i am
readdin on their site, they may have resolved that issue<br>
