<DIV id=RTEContent>Hi,</DIV>
<DIV> </DIV>
<DIV>I am reading to understand the different solutions for NAT travesal. For
nathelper+RTP proxy solution, what does the force_rport() function do? Is it
rfc3581 compliant? Does it mean that the client needs to understand "received"
and "rport" in the Via header? Thanks,</DIV>
