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@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@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
