I'm currently implementing an SIP<->SMS Gateway. For this purpose an
SMPP plugin would be great, but due to lack of time I'm using the
following setup (I'm yet not sure which setup to use for SIP->SMS).

SMS->SIP:

SMSC--(SMPP)->Kannel--(HTTP)->Apache+CGI+sipsak--(SIP)--> SIP UA

It is some "proof of concept" with a fallback to SMS->email if the SIP
UA does not support MESSAGE.

Another smart way would be using Kannel&sqlbox. This way all incoming
(from the SMSC) SMSs will be stored in a database. For outgoing SMS, you
just put them into antoher table and the sqlbox will send these
messages. Using this approach, you only have to write a module (similar
to msilo) which will store MESSAGEs into the database table. For
SMSC->SIP I also considered writing a plugin for sems which uses ser for
the SIP transport again with fallback to email.

The current SMS gateway module uses GSM modems to send SMSs.

I think an SMPP module (using kannel+sqlbox) can be implemented easy by
using the logic from 'msilo' to store messages into a database table and
using the logic from the 'sms' module to fetch SMS from antother table
and producing the MESSAGEs.

Are you interested in sharing ideas and developing code?

klaus
