Hi all, We have been planing for a long time to set up GSM mobile trunks for termination, and were planing on going with analog GSM adapters connected to a VoIP gateway. Should we be concerned with such a set-up as far as voice quality and other issues are concerned? Any experiences with GSM terminal chipsets?

The price difference is HUGE. Analog i about 66% cheaper.

Yup, even costlier than Portech. And we also tried chan_mobile as a low cost alternative, but that seems to be very buggy.
