message replies

[Iain Dooley]

hi all,

i've got a client that wants me to route message replies to various 
virtual inboxes.

i know there's the %b parameter to dlr-url which is the "original message 
in binary form" which appears to be the message id (although i haven't 
acdtually confirmed this yet).

i haven't actually played around with MO messages on my SMPP connection 
yet and it'll cost me money to set up an incoming number so what i'm 
wondering is if i use the same %b parameter in my service URL for MO 
messages will that be the original message id that the incoming message is 
in reply to?

cheers

iain
