[VOIPSEC] P2Pnat Media - A H.323 alternative to ICE

[Michael Billerbeck]

Hi Simon,

Thank you for this information.
But there are already recommendations H.460.17, H.460.18 and H.460.19 for
NAT traversal in H.323. Is your proposal concerning a different approach
than H.460.x and if yes:
Why are you using a different approach?
Are there drawbacks in the current proposals H.460.x?

Michael

Guys

This mailing has been quite for a while so I thought I'd liven things up...
:-)

A few months back I submitted a proposal to the ITU to extend H.323 NAT 
traversal capabilities to allow media to flow directly between Nated H.323 
clients rather than requiring the media to always be proxied. Basically an 
intelligent H.323 alternative to ICE

An overview of the proposal and relevant documents can be found here. 
www.pacphone.com/p2pnat.html

The proposal has been tested and incorporated into PacPhone windows secure 
audio/video softphone www.pacphone.com and the source code has been 
released open source and will be included as part of the GnuGk 
www.gnugk.org gatekeeper project (both of which I assist in 
maintaining).  You are free to test the proposal, both the softphone and 
the gatekeeper (windows installer (no vista), source code for linux) are 
freely available for download from the PacPhone website.

If anyone has any comments and feedback (throwing knives is ok too ;-) ) I 
would be happy to discuss any aspects of the proposal.

Simon
