asterisk users - Dec 2004 - Problems with incoming IAX calls...

Trying now to set up the final part of my * switch. I must admit I've had
great fun over the last week or so playing with it, and would like to thank
you guys for all the assistance (past and present, since I've been trawling
a lot of old posts!!!).

Scenario - using voiptalk.org to supply the incoming gateway, tied to an
0845 number for convenience in testing. Internal 7960 -> 7960 calls
successful. Internal -> External pstn calls also successful.
However External -> internal calls (calls to the 0845 number) don't seem
to
work....

Using IAX as recommended by most - and therefore my IAX config goes
somewhere along these lines:

[general]
bindport=4569
bindaddr=192.168.1.150
language=en
bandwidth=low

[voiptalk]
type=peer
username=username
secret=password
host=iax.voiptalk.org
qualify=yes

[08450number]
type=friend
username=08450number
context=default

and then in extensions config -

[voiptalk]
exten => _0[1-9].,1,Dial(IAX2/username@voiptalk/44${EXTEN:1})

anyone notice anything obviously wrong with these at all?

One thing I noticed was that there was no register= command in the settings,
and voiptalk don't mention it. Is it needed?? If I put one in, all I get is
continual
"Dec 23 10:34:37 NOTICE[16713]: chan_iax2,x:5970 socket_read: Registration
of 'username' rejected: Registration Refused 
(which would sort of point to me that it's not needed!!)

Anyone any hints, as I'd love to get this sorted before chrimbo..

Thanks guys!!

Paul

Rats!! Knew I'd forget some info...

Forgot this line which is also set in the extensions config :

[default]
exten => 08450number,1,Dial(SIP/2001)

Which to my mind should forward any incoming calls to the number to extn
2001..
