Hi
As mentioned in the last email, we have a CPE which adds credentials to
any request so I would like to validate them.
We use $rd as realm. Let's use example.com as example.
During the initial INVITE, this works as expected.
I try to only show the headers I think are relevant to the issue I face.
INVITE sip:1...@example.com SIP/2.0
Proxy-Authorization: [...] realm="example.com"
Contact: <sip:9876@192.168.1.1:5060>
Authentication user in realm "example.com" == $rd is validated and
accepted.
The connection is establised:
200 OK
From: <sip:9...@example.com>;tag=1
To: <sip:1...@example.com>;tag=2
Contact: <sip:1234@192.168.7.7:5060>
The caller terminates the connection:
BYE: sip:1234@192.168.7.7:5060 SIP/2.0
From: <sip:9...@example.com>;tag=1
To: <sip:1...@example.com>;tag=2
Proxy-Authorization: [...] realm="example.com"
Performing:
$var(authres) = pv_auth_check("$rd", "$avp(authsecret)", "0", "1");
fails wirh result -5 as there is no authsecret for realm "192.168.7.7"
So an unnecessarey challenge is issued:
SIP/2.0 407 Proxy Authentication Required
To: <sip:1...@example.com>
From: <sip:9...@example.com>
CSeq: 3 BYE
Proxy-Authenticate: Digest realm="192.168.7.7"
To which the client replies with the changed realm:
Proxy-Authorization: Digest username="****",realm="157.161.7.7",[...]
and succeeds authentication.
Is there a way to accept 'any' realm? Or to avoid this unnecessary
change of realm just because the remote site submitted a domain
realm in the contact header?
Mit freundlichen Grüssen
