How can I force playsms to send only msg with specify prefix ? And reject messages without 09 prefix?
The ability to manage prefixes can be in kannel.
But Im using gammu
you can route them to blocked gateway
Gammu does not provide such functionality.
Do this into playsms routing, before sending to gammu
thank you in advance.
I create outgoing route rules for all users (*) with specify Prefix to blocked SMSC. and working good.
