Hello,

I did a tcpdump as directed, the softphone I use to test (Zoiper) tries to send a register without authorization header when receiving sip 401, it sends a new register with the authorization headers. This second attempt to register  is in the log and still does not allow the correct authentication.
I took a look at the packet that kamailio is receiving and still could not find the problem, someone has idea?


        REGISTER sip: pabx999999.ligou.me; transport = UDP SIP / 2.0
        Via: SIP / 2.0 / UDP 189.13.125.28:49288;branch=z9hG4bK-d8754z-f96a8271ea34f240-1---d8754z-

Hello,

can you look at the SIP traffic and see if the realm parameter for authrozation is matching what you have in the config. The logs messages show:

Mar  7 10:59:13 p /usr/sbin/kamailio[29558]: ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=946 a=27 n=auth_check
Mar  7 10:59:13 p /usr/sbin/kamailio[29558]: DEBUG: auth_db [authorize.c:486]: auth_check(): realm [pabx999999.ligou.me] table [subscriber] flags [0]
Mar  7 10:59:13 p /usr/sbin/kamailio[29558]: DEBUG: auth [api.c:86]: pre_auth(): auth:pre_auth: Credentials with realm 'pabx999999.ligou.me' not found
Mar  7 10:59:13 p /usr/sbin/kamailio[29558]: DEBUG: auth_db [authorize.c:252]: digest_authenticate_hdr(): no credentials

Meaning that headers with expected realm were not found.

You can eventually make available the output of ngrep for a registration exposing the issue.

Cheers,
Daniel

Hello,

First excuse any mistakes in English. I'm working on a platform that makes use of integrated Kamailio with asterisk (Elastix mt).

This platform allows the login of my SIP clients via the extension number and the client's domain, where the kamailio after authentication change the username to sip EXTENSION + _ + DOMAIN (expected by Asterisk) and sends to the asterisk.

I need the client can also send the sip user in standard EXTENSION + _ + DOMAIN, for it changed the view subscriber to also return a username record in the format that the softphone is sending, but the platform still seems not authenticate the REGISTER using new way functions in auth_check ("$ FD", "subscriber", "0") and auth_challenge ("$ FD", "0").

Thus works:
Login: 101
Domain/server: pabx999999.ligou.me
Password: PASSWORD_PLAIN



This way does not work:
Domain/server: pabx999999.ligou.me
Password: PASSWORD_PLAIN


Already got a good look at the documentation and could not find the problem, could give me some help?
