asterisk users - Sep 2004 - Sending IAX2 calls back to a registered client

Greetings folks;

I guess I must be missing something, because for the life of me I can't
seem to make this work. I have remote clients connecting to Asterisk using
IAX2, these clients have changing IPs so we're using the useful register
tool.

The client can call out successfully, that's not an issue at all. Calling
coming from the server to the client, however, do not appear to go
through. I get this:

    -- Accepting call from '3015551212' to '13015559999' on
channel 0/1, span 1
    -- Executing Answer("Zap/1-1", "") in new stack
    -- Executing Dial("Zap/1-1", "IAX2/2222/13015559999") in
new stack
Sep 15 12:17:04 NOTICE[327696]: app_dial.c:714 dial_exec: Unable to create
channel of type 'IAX2'
  == Everyone is busy/congested at this time
    -- Channel 0/1, span 1 got hangup
    -- Hungup 'Zap/1-1'



The confs are a little like this:
Server iax.conf
[2222]
permit=63.149.0.0/255.255.0.0		# IP range of client
secret=pass1
host=dynamic
context=reseller
type=friend

Server extension.conf:
exten => 3015559999,1,Answer
exten => 3015559999,Dial(IAX2/2222/${EXTEN})

Client iax.conf:
[general]
register => 2222:pass1@server
[server]
type=friend
context=IAX-incoming
host=244.244.244.244		# Actual IP of server here
secret=pass1
trunk=no

Client extensions.conf:
[IAX-incoming]
exten => _2.,1,Dial(SIP/2222)

[IAX-outgoing]
exten => _1NXXNXXXXXX,1,Dial(IAX2/2222@server/${EXTEN})
exten => _011.,1,Dial(IAX/2222@server/${EXTEN})


What am I missing that is stopping the server from patching the call
through to the remote IAX2 client?

All suggestions appreciated;
JP

iax2 debug will give you more info on what is happening.

But perhaps its that you need to include a username in your dial 
"IAX2/username@2222/${EXTEN}" and put it in the [2222] entry in the 
iax.conf on the client.
