Hello, If you disable "#!define WITH_PRECENCE" you will not use presence at all - so it is most probably that you don't want that. When you use db_fallback mode, the subscribers are only written to database once in a while (in your case every 20 seconds). Also, if the subscribers are not authorized, they will only be in the "watchers" table - not active_watchers. Can you check if there is something in the "watchers" table? Also, can you check your system and see if it works without the xcap server? modparam("presence_xml", "force_active", 1) #modparam("presence_xml", "integrated_xcap_server", 1) Cheers, Marius ________________________________ From: hb <hhb.1988(a)163.com> To: sr-users(a)lists.sip-router.org Sent: Tue, May 3, 2011 11:44:16 AM Subject: [SR-Users] ： about presence Dear everyone: I use kamalio 3.1. I want to add the xcap_sever and presence modules into my kamailio. I followed the lists "http://cache.baidu.com/c?m=9d78d513d99a12f00bb6ca255001d7175b14d7226b8b814268d4e21bc22200051071e2cb30256413d2b5393447fe130baab12235775d2feddd8eca5ddcc88f3576d83034074fc71a509544b8cb31749c7f8d03baf04abce4ab6f84afa1919f03129d0f542d97f1f8030117dd6f864b62b5f18e48631e4be5af6e32&p=c0759a459d904ea904b88c3953&user=baidu&fm=sc&query=kamailio+presence+active_watchers&qid=bd42092e08822178&p1=2" step by step. The only difference is that i use the database postgresql. When i start the server, it worked well, but the softphone was not able to show the presence of the contacts. I tried many times and found that when i disable the sentence "#!define WITH_PRECENCE" in "kamailio.cfg", it can show the state of the contacts. However, when i check the database, there was nothing in "Active Watchers" and "Presentity" tables. I think there must have something wrong with the configure of presence. Any response will be appreciated. ps: the configuration of the presence in kamailio.cfg as follows(same as the Tutorial): #!ifdef WITH_PRESENCE loadmodule "presence.so" loadmodule "presence_xml.so" #!endif #!ifdef WITH_PRESENCE # ----- presence params ----- modparam("presence", "db_url", DBURL) modparam("presence", "fallback2db", 1) modparam("presence", "db_update_period", 20) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 0) modparam("presence_xml", "integrated_xcap_server", 1) #!endif haibo huang ________________________________ 体验网易邮箱2G超大附件，轻松发优质大电影、大照片，提速3倍!
