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.
