Xcap ?

Does anybody know about Xcap ? Is it interesting ? you are very kind if you tell me any experience about this one. Thank you.

It is indeed interesting. What do you want to know about it? For those that don't know, XCAP is the XML configuration access protocol, and is commonly used in SIP/SIMPLE-based voip systems to manipulate presence information. In essence, it maps XML document trees to HTTP URI's.

Thank you x-console for your reply.

I'm trying to install and test how openxcap (http://openxcap.org/) in my localhost.

could you please explain the role of Openser between publisher and subcriber ?

I've install openxcap successful, so how can I test it ?

My openxcap config.ini:

Code:

; ; Configuration file for OpenXCAP ; [Server] ; IP address and port to listen for requests ; 0.0.0.0 means any address of this host address = 127.0.0.1 port = 8000 ; The XCAP Root URI; must not contain any port number.

Openser is a client of Openxcap but how do I test if my openser and openxcap work well together.

when I run /etc/init.d/openser start
I always got this mesage:

Code:

Apr 29 10:15:45 [26607] DBG:core:shm_mem_destroy: Apr 29 10:15:45 [26607] DBG:core:shm_mem_destroy: destroying the shared memory lock Apr 29 10:15:45 [26607] DBG:core:handle_sigs: terminating due to SIGCHLD

and when I try to test:

Code:

root@dthtam:/home/dthtam# /etc/init.d/openser status Status of openser: openser is not running. root@dthtam:/home/dthtam#

Could you fix the error for me ?

Publisher and Subcriber are also Openxcap & Openser clients, do I have to install those clients on my computer to test openser and openxcap ? And could you please tell me which kind of software I should use to illustrat those clients ?

Thank million[/code]

1. OpenSER in this topology is the default proxy and sip registrar for alice and bob's phone.

2. get two phones that support xcap auth (e.g. eyebeam), and configure them for your network topology. configure your openser to use xcap

3 . I cant tell you what is wrong with your openser instance from the messages you've posted. set fork=no and look a the output for lines denoting an error.

4. erm, publish and subscribe are sip request methods issued by the sip clients (phones).

Thank you. Now I can start openser now, I just do sth like these:

Code:

#modparam("mi_xmlrpc", "log_file", "/var/log/openser-xmlrpc.log") #modparam("mi_xmlrpc", "port", 8080)

and then it works. Hopefully it is ok when I run clients. However, do you think I should install 2 kind of clients, ie. X-lite and Eyebeam/Bria. But eyebeam and Bria is not free, do you have any comment ?

x-lite does not support xcap, if i recall correctly. There are not many softphone's out there that support xcap as yet i'm afraid.. certainly not in the open source / free software space anyways.

you are right, I search in the internet, they are said that x-lit didnt' support xcap yet.

How about these:

http://uctimsclient.berlios.de/
Do you think is it ok ?

no idea.. you are best just trying them and finding out. look at the openxcap site for suggestions. The one thing about eyebeam is that it is the closest thing to an industry standard when it comes to xcap and SIp softphones. Which means you can be sure that if it doesnt work, its your configuration, and not the softphone.

Could you please tell me how can I test openser, openxcap, clients working together or to check how they are interconnected.
THank you

yes. just set them up correctly, and take traces of SIP and http to make sure all is working as it should be.

hello

mizuphone from http://www.mizutech.hu has xcap support, but it has FTP, HTTP and WebDav support as well.

I recommend you to use simple FTP or HTTP storage whenever you would like to simply store your settings and contacts on a server, and use xcap only for more advanced function (long term presence settings, etc). but in this case, the sip server you use must have support for xcap. i never seen a commercial sipserver with full xcap support untill now.
