RE: [OpenSER-Users] Presence/XCAP Problem - sr-users

22 Aug 2007

Thanks both of you. You helped me clarify two issues.

First issue is that the eyeBeam in the version I am currently using is
not compliant to the RFC. I will try to do an update, hope it is fixed
in a newer version.

Second thing I got clear about is that not the XCAP-Lite server
performes the changes in the watchers table, but the OpenSER _according
to_ the XML data, which is simply just written by the XCAP-Lite client.
Good to know.

Best regards
Sebastian

Hello,

In fact the problem with the xcap document sent by the eyebeam client is

not with that it does not comply with the draft, but with RFC 4745. The 
syntax of the 'identity' element is not as described in section 7.1.

   the latest draft
(draft-ietf-simple-presence-rules-10.txt), your 
 xcap.xml looks elder. I attach a xml that works with openser 1.3.

the changes.

Could you send in the
