Re: sms-resend-freq in sms_router

Hi,

This is really trivial. Not all messages coming at the same second into the global retry queue.
Then if we sleep for a long time then we have more messages to send.

Got it?

Thanks,
Alexander Malysh

P.S. I don't think it should be documented in the userguide because it just implementation detail.
