[Asterisk-Users] SMS to fixed phone line

[James Harper]

It seems that ETSI standard "ES 201 912" documents the protocol which is
(may be?) used in Australia.

If anyone is interested it can be downloaded from
http://www.etsi.org/services_products/freestandard/home.htm, after
filling in some soul sucking registration details :)
