[Asterisk-Users] Send voicemail notification to SMS

[C F]

If you are trying to send an SMS to a US cell phone then you can use
the email of the phone, like this:
Verizon subscriber: xxxxxxxxxx at vtext.com (where xxxxxxxxxx is the 10
digit cell phone number)
SprintPCS subscriber: xxxxxxxxxx at messaging.sprintpcs.com (where
xxxxxxxxxx is the 10 digit cell phone number)
Not sure about nextel and cingular, but I know it works with them as well.
