Re: Jxta and voip

JTAPI includes quite a lot of stuff, so it is hard for me to say if  
JXTA would only serve as a binding path. If we talk about STUN and  
uPnP then that may be true.

VOIP in the classic sense also has either a point to point handshake  
or a server that handles the setup of the call called SIP. SIP is  
sort of the telephone dial tone of VOIP. So, could you put a SIP  
server in a P2P network, sure! In fact it would wok quite well  
because if set up right, SIP is very low bandwidth.

However, the real problem is getting around NAT and firewall  
devices.  Preferably via STUN and uPnP  rather than JXTA only because  
you can get less encumbered bandwidth. A VOIP gateway is a good idea,  
especially if it is also your router and can give precedence to VOIP  
traffic.

Can you tell someone went to a class on VOIP? :o)
