[Asterisk-Users] Calling IAX client behind NAT

[Joe Dennick]

Add 
Qualify=yes
To the iax.conf file entry for this client.  That causes the client to
continue to contact the Asterisk server, thereby keeping the session
alive through the NAT.  Then when a call is imitated from Asterisk to
the client, it will just progress through the already established
session (the NAT device will actually assume it’s a response to a
client-imitated request).

Try port forwarding 4569 on the client side.

All the claims of "IAX doesn't require prt forwarding" on the wiki site
confused the hell out of me as I couldn't get incoming calls working.

Hi,

Sorry if this is a stupid question. Can I call a dynamic registered IAX 
  client localized behind a NAT ?


Client(Firefly,DIAX) --> NAT --> INTERNET --> * (public IP) --> SPA-2000
(192.168...)

The client can make calls to asterisk normally. But I can't call the 
client(lol...:). With a tunnel (VPN) this functions ok, but is to 
difficult to configuration by a simple user.
The great deal with IAX is the extreme facility to connect without any 
configuration. In FireFly, dial a URL iax://user:pass@domain is easy to 
explain and maintain.

Thanks,

Alexandre
