[Asterisk-Users] SMS to fixed phone line

I have a server monitoring both my other servers and client servers, and
I want to be notified if something goes down.

Email is fine as a first level notification method, but if the internet
goes down then obviously it isn't going to work. I used to have a modem
which would dial up direct to a Telstra modem which worked as a sms
gateway. It worked okay but has been withdrawn by Telstra.

My alternatives then are:
1. a modem to dial up the internet and send email to an email to sms
gateway
2. a subscription to a dialup sms service (Telstra do offer one)
3. a GSM modem
4. SMS to fixed line

#3 means no reliance on fixed lines at all, which could be good, but #4
sounds like the cheapest and most straight forward option.

But thanks for your opinion :)

James
