gammu support (D7)

hello

I needed support for gammu in my D7 site.

requirements
-gammu and drupal are in the same database (this could be changed, but it's easier tis way)
-gammu smsd configured and running
-drupal cron running

I created this gammu_sms module (gammu_sms).
-> It is capable of processing incoming smsses against filters.
-> it works with the gammu deamon (tables).
-> It sends smsses

The cron hook will
- process inbox smss-es against a filter, custom processing per filter is possible. examples are forwarding,replying...
- import inbox-smsses from the gammu database into the sms content-type
- included : encoding of the text to cell format, decoding to text ,

TODO:
Is it possible to integrate this with the existing sms framework, how should this be done?
Should this be a separate project (or sms-framework sub project)? How can I make this?
