Did the initiator of the conference hang up? If not, then the conference bridge will continue with the remaining participants. Any participants that join with the “endconf” flag can end the conference, the rest have no control. Example: conference(conf10@default+flags{endconf} I am just guessing, but FreeSWITCH might be doing exactly what you told it to do 😊 John Boteler Bote Communications From: FreeSWITCH-users <freeswitch-users-bounces@lists.freeswitch.org> On Behalf Of ???? ????

It happened two times. Any idea what is going on? Example from one of the calls? fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [NOTICE] mod_dptools.c:1419 Channel [sofia/external/<NUMBER>@<IP>] has been answered fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] switch_channel.c:3950 (sofia/external/ <NUMBER>@<IP> ) Callstate Change EARLY -> ACTIVE fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] sofia.c:7499 Channel sofia/external/ <NUMBER>@<IP> entering state [completed][200] fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] switch_ivr.c:632 sofia/external/ <NUMBER>@<IP> Command Execute [depth=1] conference(conf10@default+flags{}) fe4849de-cb96-4a4a-ad02-dc7485cc87ee EXECUTE [depth=1] sofia/external/ <NUMBER>@<IP> conference(conf10@default+flags{}) fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] sofia.c:7499 Channel sofia/external/ <NUMBER>@<IP> entering state [ready][200] fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] conference_member.c:1794 Raw Codec Activation Success L16@8000hz 1 channel 20ms fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 08:42:36.832268 92.10% [DEBUG] conference_member.c:1841 Raw Codec Activation Success L16@8000hz 1 channel 20ms and the next line is fe4849de-cb96-4a4a-ad02-dc7485cc87ee 2022-02-14 18:15:31.312291 95.10% [NOTICE] switch_core_session.c:407 Hangup sofia/external/ <NUMBER>@<IP> [CS_EXECUTE] [MANAGER_REQUEST] because i did hupall, but the call is still there until restart of the freeswitch itself, even after the hupall.
