I am testing behind NAT. GK is on public IP and endpoint is behind NAT. dont think so its NAT problem as i can talk easily. ----- Original Message ----- From: "Stewart Nelson" <sn@xxxxxxxxxxx> To: <openh323gk-users@xxxxxxxxxxxxxxxxxxxxx> Sent: Tuesday, September 14, 2004 03:37 PM Subject: Re: No ringing tone > Hi all, > > KO> The ringing tone is always produced from some gateway > KO> (VoIP or not) between the two endpoints. > > AS> That is incorrect.
