Manjula I just want to clarify something. SIP does not dominate the retail market SKYPE does by an enormous margin. In 90-95% of cases there should be no need to proxy media. This may vary due the number of Non-NAT aware H.323 equipment (ie gateways) that is deployed. The H.460.24 standard takes this into consideration when formulating the NAT Traversal solution and media will need to be proxied locally. The implementation in GnuGk/h323plus is not compatible with the existing implementation in PacPhone. During the ITU approval process several things had to change breaking compatibility. :( Simon -----Original Message----- From: manjula hettiarachchi [mailto:manjula_55@xxxxxxxxx] Sent: Monday, 10 August 2009 11:46 AM To: GNU Gatekeeper Users Subject: Re: H.460.18/.19/.23/.24/.24A support now inGnuGk / H323plus Hello Simon I have been using your pacphone and have been quite impressed with the features. With these new standards coming in I am sure things will further improve. However, in the SIP arena there have been lot of developments and NAT/FW traversal methods are being introduced by many parties. But there is no method in SIP to traverse a NAT/FW without media proxying. DO you think with the new standards h323 dialer will be able to traverse NAT/fw without media proxying? If yes? is a h323 still able to take a share of the retail market which is already dominated by SIP?
