asterisk users - Sep 2005 - setting up asterisk as an sms central?

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....

You're going to need to explain a little more.  When you say central
are you talking about an SMSC?

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,
