[asterisk-biz] GSM cellular network (Global System Mobile)

[Steve Totaro]

CF

Technically, sending is free.  But I assume he is sending it to 
himself.  Sure sending SMS is free through an email gateway but 
receiving it is not.  So there is no such thing as free.  Alistair gets 
the score on the SMS issue.

Sending data in DTMF, altered CallerID, or possibly a dialup modem would 
work.  Heck, voice recognition may work.  It all depends on the 
definition and purpose of the "couple of packets" that the OP is trying 
to send over GSM.

Thanks,
Steve
