The PUBLISH request works when using the following configurations(no XCAP): loadmodule "sl.so" loadmodule "mysql.so" loadmodule "presence.so" loadmodule "presence_xml.so" modparam("presence_xml", "db_url", "mysql://openser:openserrw@localhost:3306/openser") modparam("presence_xml", "force_active", 1) modparam("presence_xml", "pidf_manipulation", 1) It doesn't if starting XCAP by updating these, the server can run properly, but cann't handle PUBLISH. loadmodule "xcap_client.so" modparam("presence_xml", "xcap_table", "xcap_xml") modparam("presence_xml", "force_active", 0) modparam("presence_xml", "xcap_server", "localhost:5065") I don't know whether or not the xcap_server is set correct. There is no external XCAP server integrated. BTW, I know presence support XCAP function, does it means this module has already included a XCAP server? Thank You!
