Hi,<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>
