[SIPForum-discussion] rport in via header

[Raghul Prasanna]

HI All,
 
Does rport in via header require a value and rport is added by any hop that an Invite message transits (if the UA is behind NAT) and not by an UA, is that right?
 
 
Can someone explain more about rport with examples from any RFCs please?
