This is out of control of Kannel. The throttling message comes from the 
SMSC and it can be an error message as a reply to a submit_sm or a 
message which is not related to a submit_sm (I've once fixed this in 
the source because I had the "other" type).

There's no way to make it more elegant!

The SMPP specs dont allow for anything else. Nice would be to stop 
sending if we got "throttle" and resume when we get some kind of 
"resume" message but there is no such message. Kannel does the only 
valid thing which is wait a bit and try again.
