Yeah, I know that I can send an email to my cellphone, e.g, number@tmomail.net, but that's not what I want, nor what it looked like the SMS feature was intended to be.

The VM notification has two delivery options (plus MWI): 1) email with or without WAV attachment, and 2) SMS.

Email and MWI work, but SMS so far hasn't for me. Sure, I can setup my mail server to copy the notification to my inbox and forward my phone, but I want WAV attachment on my inbox and not on my phone (ok, I can further setup more complex rule on my mail server to drop the attachment before sending to my phone)... but... all that is unnecessary if SMS just works at it should.

I have a ticket open for this.. will post update.
