Hi All, Here is my problem: we are using the Freeswitch conference(mod_conference), when conference starts, we want it to automatically call group members in, so we use conference_set_auto_outcall like this: <action application="conference_set_auto_outcall" data="user/1000@$${domain}"/> <action application="conference_set_auto_outcall" data="user/1001@$${domain}"/> <action application="conference_set_auto_outcall" data="user/1002@$${domain}"/> <action application="conference_set_auto_outcall" data="user/1003@$${domain}"/> ...... but very often, there are some members which delay significantly(most about 10s, sometimes 3~4s) from conference call(3001) to it rings, while other members rings with no delay. And, if we make a second conference call instantly after last conference ends, the delay almost never happens. The longer the interval is, the bigger is the delay chance. When we tryed to use some packet capture tool to analyze, we found that SIP INVITE packet for the delayed peer was sent 10s after conference call, and there was no SIP packet at all during the 10s delay, So the delay is from serverside. The question is, may there be something wrong with our FreeSWITCH configuration, or the delay is as intended for some purpose? How can avoid the outcall delay and make all peers ring at the same time when conference starts? Thanks and Best Regard, David
