hi
is it possible to use asterisk as an sms central to send SMSes directly
to clients on PSTN instead of just communicating with a central? the
telco to which we're currently connected doesn't have a central....
Yes, as far as you can spoof the Caller ID ;)
The trick is that PSTN clients decide whether an incoming call is a SMS
or not *before* answering, by looking at the Caller ID, and they are
usually pre-programmed with the SMSC's phone number. (At least, that's
valid for the SMS-capable analog cordless phones I've seen till now.)
So, that's going to be a problem, unless your telco is willing to help
you at least in that respect, and let you send a valid SMSC's phone
number as caller ID.
(Of course I haven't tried this across the public network, but I'd be
ready to bet one or even two beers that it works!)
Bye,
