ep3 (192.168.0.9)
ep1 can make calls to ep2 and ep3. ep2 and ep3 can also makecalls toep1. and ep3 can make calls to ep2, but ep2 can't make call correctly toep3.
when ep2 calls ep3, ep2 can hear from ep3, but ep3 can't hearanything.so i captured the packages. i found that the tcp packages were tunneledby GK, and the RTP packages transferred directly between ep2 and ep3.but the RTP packages from ep2 to ep3 are in wrong destination UDP port.
the ep3 sends RTP packages as 192.168.0.9:6002 --> 10.0.0.2:6000,andthe NAT3 transferred them to 10.0.0.33:1284--> 10.0.0.2:6000. then the RTP packages to ep3 that back from ep2 are10.0.0.2:6000-->192.168.0.9:6002. and the NAT3 does not transfer them toep3, then the RTP packages can't reach ep3.
i use Routed mode to the GK. am i right? or wath shall i do?
