We use OpenVox G400P cards  (PCI; newer motherboards probably will require 
G400E which is essentially the same card but with PCI Express interface)  for 
our SMS and mobile telephony needs.  Just slot in up to 4 SIM cards, and 
install chan_extra.

Incoming text messages trigger an extension in your dialplan with some channel 
variables set, so you can respond to the message  (and also are recorded in a 
logfile).  Outgoing messages can be sent using the Asterisk CLI.  In principle, 
anything that you can call from a dialplan can be initiated by an incoming 
message, and anything that can execute a system command can initiate an 
outgoing message.
