[asterisk-users] Asterisk GSM Gateway Project

[Jason Aarons (US)]

Google multitech CallFinder 100, has both FXO and FXS interface you can
connect.

Problem is you call out and don't get simulated ring back while the GSM
call is being setup.

There is a commercial product that does just that.  I cannot reveal
the company name since they are clients of mine but they have a BTS, a
retractable 15 foot tower, a laptop or small PC running Asterisk and
either do VoIP over VSAT or connect via T1/E1.

Mostly government work but they are busy and growing very fast.

Thanks,
Steve Totaro
