Hi Steve!

Thank you very much!
It seems to run!

I wrote that:

exten => _00493513333333,n,Set(__ALERT_INFO=Bellcore-r3)
exten => _00493513333333,n,SIPAddHeader("Alert-Info:<http://www.notused.com>\;info=alert-external\;x-line-id=0")

and the phone rings with another melody.
Very curious is, that if I don't write BOTH lines, it does not run...

And, unfortunately, I just have two melody: the "normal" and this one, but it
is better than nothing!
Now, if it will be possible to add a text on the display, it will be perfect,
but I didn't found any option for that...

Thanks
Luca Bertoncello
