So to clarify... Incoming calls to my SIP trunk, via Unlimitel, when the
caller enters the extension (which is a person working on the internet a
few cities away using a SIP Softphone like X-Lite), will always have the
call data go through the Asterisk box until the call is completed. It
will NEVER pass the call to the extension so that the originating call
from Unlimitel talks directly to the user's Software at the extension
(by passing the Asterisk box). Correct?

And if I want to allow this, my Trunk provider must allow "reinvite" (in
which case Unlimitel does not allow).

Are there any other possible ways to accomplish this that you know of?

Are you aware of any Trunk providers that allow reinvite?

Regards,

Chuck

I don't believe Unlimitel supports reinvite's yet. If it does though,
the 'reinvite' option needs to be set to 'yes' for both the trunk and
the client in sip.conf

If you look at the network traffic while on the asterisk box, you
shouldn't see much of anything if you do a tcpdump something like this
as root:
# tcpdump -i <your external network interface, likely eth0> not port
5060 and host <ip address of client>
