Folks! I am looking at a couple of models of Fixed GSM Gateways for the Purpose of VOIP connectivity and specifically to work with Asterisk. I found that these can be imported into USA for about $99.99 or about that. This is a one channel unit just like tellular, one of them has GPRS.
FCT11M: 1)freq: GSM network,900/1800/1900Mhz, 2)provides reversal signal for payphone/billing 3)supports PBX and VOIP 4)for voice (no fax) 5)battery(optional) 6)can be used for the remote area where signal is weak.

I am pasting an image of the network diagram here: Specifications in text are below. I would appreciate for any feedback of their usability. Seshu -------------------------------------------- Description: ----------- This unit can conveniently access to the available GSM system network. This system possesses such a high receiving sensitivity and a large transmitting power that it expandsthe effective coverage of the cellular network to a larger geographic area (upto 15 miles). The unit has been extensively used in the fixed access to the cellular network to solve the wired communications problems in the rural areas. It can also be used to develop fast radio public telephone services to satisfy the communications for the time being and work as the CO relay tosimplify the registration s and lower the cost. Furthermore it can meet the requirement of mobile communications onboard vehicles, ships, trains, etc. All these enlarge the number of the network subscribers considerably so that it can utilize the resources better.
