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

[Steve Totaro]

Tmobile charges $15/mo unlimited SMS it is $.05 or $.10 each with no SMS 
plan.  Not very expensive.

You could send the data in your callerid and use dialplan logic to strip 
it out.  I used to do that with UniqueCallIDs to remote call centers so 
we could match up recordings (they would do the recording filename by 
callerid) with CRM records later.

Thanks,
Steve
