The price difference is HUGE. Analog i about 66% cheaper.
But you then need some sort of analogue adapter/interface to feed the
analogue GSM module...
Although if you've already got this, it's a obviously a cheaper option.
However, here in the UK, the price difference isn't that bad, but it might
be that the number of ports you'rea fter makes a difference - e.g. a
2-port SIP Portech units is £321, a single (analogue) port Telecom FM unit
is £119. (so actually slightly cheaper for 2 ports with SIP Ethernet
Interfaces here), but if you're looking at a dozen channels it might well
be different..
However - to your original question - I've used both the Portech and
Telecom FM units (on a TDM 400 card) and not really been able to tell the
difference. The Portech dials quicker, the Telecom FM obviously needs to
get the number passed via DTMF, but since GSM is ... GSM which is pretty
poor speech quality to start with, it didn't make any difference I could
tell.

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?
Why not SIP based GSM devices? e.g. Portech?
