Hi, The full log helped me see what is going on. Rather embarassingly it is a Linux command line or curl error. This command:
curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:1...@multifon.ru/index~~/presence/tuple%5b@id='x8eg92n'%5d/note doesn't work, but this command: curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:1...@multifon.ru/index~~/presence/tuple%5b@id=\'x8eg92n\'%5d/note does. Something was removing the ' characters from the URL.
