I read the sipura documentation more specially about the NAT Support Parameters ;
I would like to know if it is the same way to use Handle VIA received, and Handle VIA rport as EXT IP and EXT RTP Port Min .
My second question is, if we use the received=A.B.C.D. and rport in the SIP VIA header does the UAC or the UAS will contact the ip A.B.C.D for the RTP session ? Thanks
