Subject: Re: [asterisk-users] why is nonce="584760da" used in
sip packets?
This causes the asterisk server to send another unauthorisation
response with an additional parameter stale in WWW-Authenticate section
as shown below
<--- Transmitting (NAT) to 208.120.167.146:80 --->
SIP/2.0 401 Unauthorized
Via: SIP/2.0/UDP
208.120.167.146:80;branch=z9hG4bK722c974c;received=208.120.167.146
From: <sip:[EMAIL PROTECTED]>;tag=as1acc7245
To: <sip:[EMAIL PROTECTED]>;tag=as1d329593
Call-ID: [EMAIL PROTECTED]
CSeq: 19710 REGISTER
User-Agent: Asterisk PBX
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE,
NOTIFY
Supported: replaces
WWW-Authenticate: Digest algorithm=MD5, realm="asterisk",
nonce="4f90fab4", stale=true
Content-Length: 0
this stale=true field causes the asterisk server to display the
following NOTICE on the cli
NOTICE[8380]: chan_sip.c:8151 check_auth: Correct auth, but
based on stale nonce received from '<sip:[EMAIL PROTECTED] >'
and this will continue happening unless the next register
request uses the nonce field recieved in latest unauthorisation response
from server, and untill then the user agent will not be able to register
with the server. This will cause problems in our services.
