[asterisk-users] What means? Correct auth, but based on stale nonce received

[Tiago Durante]

Hi masters!

I've this Asterisk 1.4.15 running. yesterday I had to change the
firewall schema that I had before.

I use to have a FW that would be my network FW/Proxy and do the NATs
for Asterisk. This FW was receiving too many requests from my LAN and
it was making the Asterisk 'cut' the calls or reach very high latency.

Yesterday I added a new FW just for this Asterisk. The same
configuration as the old firewall, loading the same modules, same
NATs.

But now some ATAs (sip) can't register against this Asterisk and the
ones that can generates these messages:

[Apr 14 13:01:45] NOTICE[29235]: chan_sip.c:8375 check_auth: Correct
auth, but based on stale nonce received from
'sip:XXXXX at 200.X.X.X:5060'
[Apr 14 13:01:45] NOTICE[29235]: chan_sip.c:8375 check_auth: Correct
auth, but based on stale nonce received from
'sip:XXXXX at 200.X.X.X:5060'

Does any one know why this happens?

Thank you!!!
