You need to figure out where the 'forbidden' is coming from.  If you
look at the SIP 403 response in the logs (I don't know if x-lite let's
you see the whole message) you may be able to tell from the Server
header.

If not, then you'll need to trace the message flow and see
what's going wrong.  See:

http://wiki.sipfoundry.org/display/xecsuserV4r0/Display+SIP+message+flow+using+Sipviewer

when you get the trace data, take a look at it using sipviewer
and/or post the trace with a description of your configuration
(identify components by IP address), what you were doing, and
which call in the trace you're talking about (by call-id or
frame number in the trace, preferably).

If the Forbidden is coming from sipXproxy, then you have a problem with
the permissions required by your dial plan and given to your user.

If it's coming from your ITSP, then you need to change how sipXbridge is
configured (and/or change how the ITSP is provisioned)
