Is there a way for kannel to not forward to SMSC SMS whose destination numbers are less than a specified number of characters.

Hi,

I am using Kannel 1.4.3 and am looking for a means for the gateway to
drop messages destined to numbers with missing characters. The reason
being sometimes clients send texts to numbers less than the in-my-case
acceptable 12 digits and the NOs charge me for them.

Regds,

Engel
