asterisk users - Mar 2005 - Unable to create channel of type 'IAX2'

Hi all,
I'm a newbie and I have a configuration problem with Asterisk.
Seems that I'm not able to call an outbound number. I'm quite sure that
it
is a configuration problem, but I'm not able to find out where is the 
mistake, even reading several docs to www.voip-info.org.
I do not have a good knowledge of Asterisk, I'm not very familiar with its 
configuration and I've a big confusion about it.
Any help will be appreciated.

When I try to call outside I got the following message:

*CLI>     -- Accepting AUTHENTICATED call from 192.168.0.55:
       > requested format = ilbc,
       > requested prefs = (),
       > actual format = gsm,
       > host prefs = (gsm|ilbc|speex),
       > priority = mine

You didn't read all the messages, see:

"IAX2/3479450772") in new stack

chan_iax2 says you have no section in your iax.conf telling it what
3479450772 is, *therefore* it couldn't create the channel.

Always read *all* the messages, especially the first few since they may
indicate something that may cause a failure later.

FWIW, you probably wanted IAX2/target/3479450772.

Hope this helps,

You are telling it to dial ALL 10 digit numbers using IAX. What you
need to do is have an extension that determines if a call is meany for
the X100P and if so the dial would be
> exten => _XXXXXXXXXX,1,Dial(ZAP/1/${EXTEN})
ZAP/1 is your X100p FXO.

Take a good look at http://www.asteriskdocs.org which was entirely
written to help you understand channels, extensions and dialplans.
These are the essential building blocks to get you going.
 
You will need further knowledge to separate internal extensions from
external phone numbers. Often internal extensions are numbered like
2000,2001,2002...

example 
> exten => _2XXX,1,Dial(IAX2/${EXTEN}) ; hand all 4 digit numbers that
begin with 2
