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,
