Hello,
this sounds like a missrouted ACK. Please watch the network traffic on
your server and see if the ACK is sent properly to the callee. You can use:
ngrep -d any port 5060
on your sip server machine.
Cheers,
Daniel

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 <http://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,
route{
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
