[asterisk-users] 401 Unathorized

I have an asterisk 1.8.x box that intermittently returns a 401. Calls come
through the same peer all the time, from the same carrier. However
intermittently the asterisk box returns a 401.

Below is the output of a failed call (1st) and a successful call (2nd). I
can't see any difference until we get to these lines.

Bad call:


--- (17 headers 14 lines) ---
Sending to carrierIP:5060 (no NAT)
Using INVITE request as basis request - 41597440-0-320116780 at carrierIP
Found peer 'phonenumber' for 'phonenumber' from carrierIP:5060

<--- Reliably Transmitting (NAT) to carrierIP:5060 --->
SIP/2.0 401 Unauthorized


--------
Good call

--- (17 headers 14 lines) ---
Sending to carrierIP:5060 (no NAT)
Using INVITE request as basis request - 41604639-0-321360830 at carrierIP
Found peer 'carrierIP' for 'phonenumber' from carrierIP:5060
<--- Transmitting (no NAT) to carrierIP:5060 --->
Call proceeds here.

-----

It's all coming from the same carrier IP and the same SIP trunk. All are
set via static IP (No registrations). And nat is set to no (Everything is
on a public IP).

Has anyone else run across anything similar?

Thanks
David
