Even if you get one, you won't use it, just because the windows people are using Skype. Or perhaps you mean an Open Source Skype client? It is as bad than running the original client as you would still be using a proprietary protocol. > Anyone knows what's happening on the side of the SIP/H323 standards with > regards to NAT? Any planned standard enhancements? > The problem is not with SIP or H.323. The problem is with NAT itself. The day when the Linux Kernel and most hardware routers will natively support SIP (or H.323), then you will have no problem to go through NAT with software like GnomeMeeting. Perhaps it is too late for H.323, but most hardware routers start supporting SIP natively, which means that you can be behind that router, and call anybody without any problem. Of course, at least one port forward is still required if you want to be able to receive incoming calls. As for GnomeMeeting and H.323, we provide several ways of going through NAT in the CVS version : - Using a STUN server, if your router supports any type of NAT except Symmetric NAT (the linux case) - Using a gatekeeper (if I had money, I would pay for a public one) - Using IP tranlsation and port forwarding - If you are calling a GnomeMeeting user on a public IP, or behind NAT with IP translation, you don't need to be configured anymore, it will cross the NAT. Finally, FWD is providing public SIP outbound proxies, which means that people can use them with SIP clients allowing to transparently go through NAT without any configuration *even* if your NAT doesn't support SIP. That's equivalent to the gatekeeper case above. > I wonder why Microsoft doesn't get their own product... They probably understood that there is no future if they do not support standards for VoIP.
