asterisk users - Feb 2005 - Problem with SPA-2000 and Asterisk 1.0.5

I had everything working fine until today.  Today the Sipura cannot dial
anywhere.  I just get the following:


Feb 10 12:48:18 NOTICE[1205]: chan_sip.c:7399 handle_request: Unable to
create/find channel
Feb 10 12:48:19 NOTICE[1205]: chan_sip.c:7399 handle_request: Unable to
create/find channel
Feb 10 12:48:35 NOTICE[1205]: chan_sip.c:7399 handle_request: Unable to
create/find channel
Feb 10 12:48:35 NOTICE[1205]: chan_sip.c:7399 handle_request: Unable to
create/find channel

     Every time you pick up the phone and dial anything the above appears in
the console.  The strange things is that I can dial to that extension and talk
without problems.  I did not change anything on both sides that may account
for a problem, it just started today.  I did a factory reset on the Sipura and
re configured it and I still have the same problem.

     I don't know what to do next.  Any ideas?

I've recently encountered the same issue here.  I've narrowed down the 
problem to be authentication failures, although it doesn't readily say 
it.  See if this doesn't clear up if you remove the secret= line from 
the user/friend entry in sip.conf, and from the UA (sip client).  If so, 
then could you please email me off list with your network setup so I can 
attempt to make a determination of wether or not there's something 
similar in the setup?
