We use OpenVox G400P cards  (PCI bus; there's also a G400E, which is PCI 
Express)  for this purpose.  Available with up to four GSM modules, each of 
which uses one SIM.  The driver for this card is called"chan_extra", it's Open 
Source and gives you some more commands in CLI  (including the ability to send 
SMS messages),  as well as a new technology "EXTRA" which you can use as in

[outgoing_via_mobile]
exten => _0X.1,NoOp(Outgoing call via mobile to ${EXTEN})
exten => _0X.,2,Dial(EXTRA/r1/${EXTEN},180)

Incoming calls via the SIM's number can have a default context assigned in 
/etc/asterisk/chan_extra.conf, and then they just turn up in your dialplan as 
normal.

Incoming SMS messages trigger an extension in your dialplan, with some channel 
variables pre-set for you.  SMS acknowledgements  (successful or otherwise)  
trigger yet more extensions.
