Hello,

there is no "xcap" module, it looks like only xcap_server module is in use, which has nothing to do with initiating GET requests, but respond to them. There is xcap_client module, which should do HTTP GET, but it does not seem to be used.

Looking at http traffic in the email, the xcap clients are jitsi and blink, they do GET and receive 401 from kamailio, and they should follow up with a new GET having authorization header, which is actually done by jitsi.

At this moment, it does not seem anything related to kamailio, or at least not a situation when kamailio has to do any GET.

Try with jitsi and kamailio newer version, see if works, if not look at the logs of jitsi to see if it complains about anything.

Cheers,
Daniel

Hello,

 

Thanks. From 3.1.x to 5.6.x is a long time with a lot of changes. Hard to say why this happened.

Maybe somebody else can who knows more details can comment as well.

 

You could run some tests with different versions to find out when it was broken on your side.

This can also be done by e.g. by compiling from the git and checkout the appropriate tagged versions.

Using “git bisect” might be also helpful to find it faster. If you found out some more, please open an issue on our tracker.

 

Cheers,

 

Henning

Hi Henning,

 

Right. xcap module could NOT work fine on the last version of Kamailio (5.7.0)

 

see the following log:

 

GET /xcap-root/xcap-caps/global/index HTTP/1.1

Accept-Encoding: identity

Host: 192.168.3.88:5060

Connection: close

HTTP/1.1 401 Unauthorized

Server: kamailio (5.7.0-dev1 (x86_64/linux))

Content-Length: 0

 

 xcap module on 5.7.0 will NOT send the "GET" message with digest, when get 401 response. But on 3.1 works fine.

 

I already check the xcap module manual, https://kamailio.org/docs/modules/devel/modules/xcap_server.html  I don't find more configurations.

 

Could you please give more hints?

 

Thanks!

Hello,

 

Generally you should use a recent and maintained operating system and also a maintained version of Kamailio  (5.5.x or 5.6.x).

 

Are you saying that the xcap module work in Kamailio 3.1.x but not anymore in a newer version?

 

Cheers,

 

Henning

Hi Sir/Madam,

 

I set up Ubuntu 10.04 + opensue3.1, then the xcap module work fine.

 

Then seems the last version xcap module could NOT send the "GET" message with digest, when get 401 response.

 

Is there any parameter which should be set, in order to fix it? 

 

Thanks!
