Re: [Serusers] NAT Problem No Voice

I quickly reviewed the config, but couldn't see any immediate issues, the ACKs should go through fine. Could you supply an ngrep trace of faulty call setup? g-)

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
