SAR needed!!!!!!!!!!!!!!

Hi everyone,
   I tried to fetch a large wml-text (around 30k) with a wap-phone through
the wap gateway. (I'm using kannel 1.2.0)

Then some error....
WSP: Entity at http://my.wap.gateway/wap/t.wml too large (size 23249 B,
limit 3000 B) 

I guess this is something to do with SAR. Correct me if I'm wrong!!

 Has anyone start coding SAR capability. If so, pls let me know the progress
 Does anyone know how and where to start coding ? Or just lead me to any
good documentation describing the architecture of kannel. ( posting what u
have done up to now would be a great help ).

Urs,
Denzel.
