[Asterisk-Users] NAT Far End Traversal

[Cameron Beattie]

I am very interested in this idea, mainly from the "protection from a 
hostile telco" point of view. What are the problems that this is likely to 
cause: additional overhead, delay, firewall problems etc?

Perhaps this is a little off-topic and should be discussed in another forum 
but if people are interested I would appreciate your input.

The Zulty's phones support VPN. Then again, many firewalls don't pass

through VPN traffic nicely. Would be cool if we can have a phone that

supports SSL VPNs like OpenVPN.
