The nonce is globally valid until it expires (for all kind of requests,
IIRC you could also change the user).
Maybe your "internal" SIP clients calculates the response wrong. You
could test the response calculation with this website (do not use 'real'
passwords):

Hello,
I am working on Kamailio 3.2.2. There is no traffic, only functional
test done.
Based on the SIP Client used until now (Xlite), the INVITE is
systematically authenticated by 407 as there is no Proxy-Authorization
in the initial INVITE. Expected/normal behavior.
But when using an internal SIP client, the initial INVITE is generated
with a Proxy-Authorization containing the nonce value used by the
successful registration.
_In Authorization of Register (the answer is 200OK)_

_In Proxy-Authorization of Invite _

As the nonce expire is high (see nonce_expire), I don't understand why
Kamailio requests the Authentication of the INVITE by 407.
_407 with Proxy-Authenticate_: Digest realm="ims.v0.pftest.net",
nonce="UDP6pVAzpkWDF+jSlP3zzVYcuNPhY8NQBj62WIA=", qop="auth",
stale=true
*Does it mean that the REGISTER and INVITE are using different Nonce
value ? *
èInformation on my configuration file.
modparam("auth_db", "db_url", DBURLAUTH)
modparam("auth", "auth_checks_register", 6) # callid and From TAG
modparam("auth", "qop", "auth") # enable qop=auth

For register, I do
if (!www_authorize("$ru", "subscriber"))
{
if($? == -2 || $? == -3) {
sl_send_reply("403","Forbidden auth ID");
exit;
}
else {
www_challenge("$ru", "17");
exit;
}
}
For invite, I do
if (!proxy_authorize("$fd", "subscriber"))
{
if($? == -2 || $? == -3) {
sl_send_reply("403","Forbidden auth ID");
exit;
}
else {
proxy_challenge("$fd", "17");
xlog("L_INFO","INVITE challenged by 407 to :$di:$dp
\n");
exit;
}
}
Followed by consume_credentials();
Thanks in advance for your support.
