The eyebeam has referenced a private address in the SDP ( 172.16.114.1
), it is my understanding that since this IP is not routable, you'll
never get any audio. I believe the purpose of RTPProxy is to bridge
calls that are behind private IPs. <br>
<br>
I believe you'll need an RTP Proxy or Media Proxy to fully support
crossing NATs. <br>

<br>
My kamailio and application server are with Public IPs so the
system uses nathelper without RTPProxy. It works with the eyebeam
behind the ADSL router, but I cannot hear any voice ( ethereal capture
on the PC shows no RTP from the application server) when try it in a
Hotel or with a 3G data card. Below is the SIP messages for the issue,
is there anyway can fix the issuse? <br>
