The SMSq stuff is for landline-type SMS, like those that never became
really popular here in Europe ;-) I do not know of any SIP hardphone
that supports them, but regular analog and ISDN handsets behind a
SIP-to-analog/ISDN gateway work for me.

The point of this SMS transfer method is calling the destination handset
with a certain callerid set (which differs between countries - whatever
number the telco prefers to choose - this can also be configured in the
phone). The phone will not ring but instead immediately answer the call
and receive the short message at 1200bps whatever modem standard they
chose to use.

For sending SMS, the handset will call a similarly telco-provided number
(premium-rate numbers here in Germany - maybe that is the reason for the
lack of popularity of this service) and do that 1200bps talk.

If you still think you can make use of it, make sure to call "smsq" with
the user id that asterisk is running as. That _might_ already do the
trick. If you do not get it running, ask again - I might have a working
setup somewhere around ;-)

Nevertheless, for me, landline SMS is a PITA. The only great thing is
you can upload Ringtones to Siemens gigaset phones.
