Hi all,
 
Is SER a B2BUA for IM, voice etc?
 
i.e. If user A sends an IM message(via SIP MESSAGE) to SER, and SER sends the message to user B.
 
Seems like it is not, because the Call-IDs are the same on both call legs....
 
Is there any special configuration which can turn it into a B2BUA?
 
Regards,
Dennis
