Authentication error with chan_sip

[jeanfrancois.barsocc]

Hi
I have an Asterisk server (chan_sip) with a proxy server (Kamailio).
when I make a call, I have an authentication error from asterisk, I can’t get why.

First, proxy send sdp invite and receives 401

then proxy sends another invite but anthentication fails

could someone help to find th reason of the authentication failure please ?

You haven’t provided configuration, or explained how you expect it to work.

hi. UAs register on proxy and proxy relays to the asterisk.

here is my sip.conf:

allow=alaw|ulaw
;deny=0.0.0.0/0.0.0.0
callcounter=yes
directmedia=no

videosupport=yes

prematuremedia=yes

do you need more informations ?

I don’t have anything to add, nothing sticks out and I don’t personally spend much time on helping people with chan_sip anymore. By providing the additional information someone else may have input themselves.
