hello
its working now using RTPProxy.
(PrivateIp)UA<------->SER<--------->UA(PrivateIP)
(PublicIp)UA<------->SER<--------->UA(PrivateIP)
(PublicIp)UA<------->SER<--------->UA(PublicIP)
the only problem i am haveing in this setup. sometimes
with accepting ACK.
Actuallying some time call is disconnected on one UA
but on other side UA is not disconnecting this call
example
UAC(publicIP)-------->SER---------->UAS(privateIP)
UAC<-------RTPProxy------>UAS(display message
"awaiting ack" after some time it is terminating call
And displaying message "ACK TimeOut")
and if it HangUp call from UAC(publicIP)
UAC----->SendingBYE------>UAS (UAS is not
disconnecting call and saying "waiting for ACK" and
after sometimes display message "ACK Timeout")
any comments
