There should not be any problem if they use multiple IP addresses for media stream, as long as siptraffic's SDP contains correct IP that will participate in RTPs exchange...
Do note that media IP can be different from sip IP, and it is OK, if implemented properly...

Seems like siptraffic uses 6 ip addresses for media, can that be the
problem? Is there any setting in a gateway config xml which helps with
that?
I will do ngrep thing and update.
