Hi Users,
I install the openser 1.0.1 and rtp proxy 0.3 in same Linux System openser server is located with public id xx.xxx.xxx.xx of 192.168.2.2 , And UAC are outside the NAT, When one UAC call to other UAC( are both in outside the NAT where openser server), after the INVITE method get request by server, after 32 second its hung up automatically, Voice is ok , and callee is hung upping, not caller, UAC ( inside the nAT , openser server ) in not hung uping and voice is not ok.... Where is the problem, in NAt with rtp or networking,
