[Asterisk-Users] IAX over HTTP

[Julio Arruda]

Just remember that TCP will try to retransmit your lost voice packets, 
what is not exactly of any use :-).

VPNs with IPSec and others (CIPE and some UDP 'related' vpns) would not 
create this extra (and useless) overhead.
I've used IAX over OpenVPN (with SSL as you), and it does work, to some 
level, but I would not do it for a living :-)
