Dear All, I am working on XMPP module of kamailio server (V-4.0.2), intended to achieve File transfer, IM features. Firstly my Kamailio and Jabberd2 servers are on the same machine. I managed to separately make them work. Call setup between SIP clients is working and so with messaging/presence, File transfer functions for Jabberd clients. But when i integrate both the servers by using xmpp module, i can only send messages to SIP clients from XMPP client (one way) but i cannot send messages to xmpp clients from SIP clients. Off course the *presence is not sharing* between these SIP and XMPP clients. My clients URI and JID syntax are looking like this: ---> SIP client (registered to kamailio server): *112@sip_domain* ---> XMPP client (registered to Jabberd server): * 114*sip_domain@jabber_server *(Is this syntax is correct?) And in SIP client contact list ,added an XMPP user which look like this: *sip:114*sip_domain*jabber_server@gateway_domain * In XMPP clients buddy list, added a SIP client which looks like this: * 112*sip_domain@xmpp_domain* Is the above syntaxes are correct ? Following are my working domain names(for your reference): sip_domain ---> kamailio.kamailio.test xmpp_server host ---> xmpp.kamailio.test gateway_domain ---> sip-xmpp.kamailio.test xmpp_domain ---> xmpp-sip.kamailio.test. And my syslog is giving the errors like this: Oct 1 18:40:57 kamailio /usr/local/sbin/kamailio[18710]: INFO: pua_usrloc [ul_publish.c:221]: ul_publish(): not marked for publish Oct 1 18:41:21 kamailio /usr/local/sbin/kamailio[18714]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Duplicate entry '112-kamailio.kamailio.test-presence-*#-OFFLINE-#*' for key 'presentity_idx' Oct 1 18:41:21 kamailio /usr/local/sbin/kamailio[18714]: ERROR: <core> [db_query.c:337]: db_do_update(): error while submitting query Oct 1 18:41:21 kamailio /usr/local/sbin/kamailio[18714]: ERROR: presence [presentity.c:1281]: mark_presentity_for_delete(): unsuccessful sql update operation Oct 1 18:41:21 kamailio /usr/local/sbin/kamailio[18714]: ERROR: presence [publish.c:171]: msg_presentity_clean(): Marking presentity Oct 1 18:41:21 kamailio /usr/local/sbin/kamailio[18723]: INFO: presence [notify.c:1601]: send_notify_request(): NOTIFY sip:114*kamailio.kamailio.test*xmpp.kamailio.test@sip-xmpp.kamailio.testvia sip:114*kamailio.kamailio.test*xmpp.kamailio.test@sip-xmpp.kamailio.teston behalf of sip:112@kamailio.kamailio.testfor event presence. Please below find the attachment of my kamailio configuration file. What could be the wrong ? How can i solve this issue ? And why the presence is not visible between the clients even after integrated pua_xmpp module in script ? PS: set-up credentials are : XMPP client ---> pidgin SIP client ---> Jitsi Any help will greatly appreciate. Regards, Nandini
