[Asterisk-Users] IAX over HTTP

[Eric Rees]

We have been running IAX through OpenVPN with SSL for 6 months without
any trouble to Las Veags, and we are in Oklahoma.  Most of the time, IAX
sounds better then the land line.

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 :-)
