As others have noted, for this to happen the "proxy" (proxies?) needs to
modify the SDP to cause this to happen. If it does this it has violated
the rules for a proxy. Devices that do this are typically called Session
Border Controllers. It is very common. There are both advantages and
disadvan
Check the 'c' line in the SDPs exchanged, proxy might also be acting as a RTP
proxy / relay.

Hello,
this is possible only if SDP "c" line (connection information) is modified,
most probably an RTP proxy is also active on your SIP server.

Hi all,
I saw a RTP flow which is not directly established between UAC and UAS but
goes through a SIP proxy ...
Is there any information in SIP message exchange producing this situation ?
Thanks for your help,
ikuzar
