Re: Throttling Error

Hi

Eventhough, as told by Andreas, what you are being required is not
part of smpp specs, your best bet is to hack kannel code and generate
a patch for that.

Check code of smpp module to where it checks for throttling error and
add something like  IF (ThrottlingError) { sleep 60000 }

This way your smsc-smpp will sleep for the specified time whenever it
detects a throttling error. Note that this WILL DELAY AND SLOWDOWN
your queue to this smsc. I don't know kannel code so it might also
impact other parts of kannel.

Regards

Alvaro
