Hi Using Kamailio 5.4 with Asterisk 18 and using the pjsip outbound-publish to allow Kamailio to handle BLF for phones. BLF sort of works, in that when a line is on a call, the BLF reflects that. However the early/ringing state does not generate a NOTIFY to the phone, although Asterisk is sending the Publish and is receiving a 200OK reply from Kamailio. I would presume that since basic BLF is working that this early state PUBLISH should generate a NOTIFY but it doesn't Module params are as follows: # ----- presence params ----- modparam("presence", "db_url", DBURL) modparam("presence", "server_address", "sip:192.168.245.250:5060") modparam("presence", "local_log_level", 3) modparam("presence", "publ_cache", 0) modparam("presence", "timeout_rm_subs", 0) modparam("presence", "sip_uri_match", 1) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) modparam("presence_dialoginfo", "force_single_dialog", 0) modparam("presence_dialoginfo", "force_dummy_dialog", 1) Any help appreciated! -Barry
