Hello All, I am working on the process to setup announce user name who join/leave the conference. For this first it was required to setup a process to record the user name while joining the conference, this patch attached with this mail is programmed for this but I have some issues with file format... Conference Syntax: confname+flags{introuser}+1234 Freeswitch log: 2008-10-15 07:29:25 [NOTICE] mod_conference.c:4537 conference_function() Conference member introuser flag set. 2008-10-15 07:29:25 [NOTICE] mod_conference.c:4548 conference_function() Conference 77777 INTROUSER set. 2008-10-15 07:29:25 [NOTICE] mod_conference.c:4550 conference_function() File Path is /tmp/conference_member_77777.wav 2008-10-15 07:29:31 [NOTICE] mod_conference.c:464 create_file() File Path as in create_file is /tmp/conference_member_77777.wav 2008-10-15 07:29:31 [ERR] mod_sndfile.c:144 sndfile_file_open() Error : file format is invalid (0x00010000). 2008-10-15 07:29:31 [NOTICE] switch_ivr_play_say.c:403 switch_ivr_record_file() Hangup sofia/internal/1000@192.168.0.3:5061 [CS_EXECUTE] [DESTINATION_OUT_OF_ORDER] 2008-10-15 07:29:31 [ERR] mod_sndfile.c:175 sndfile_file_open() Error Opening File [/tmp/conference_member_77777.wav] [System error : No such file or directory.] 2008-10-15 07:29:32 [NOTICE] switch_core_session.c:833 switch_core_session_thread() Session 1 (sofia/internal/1000@192.168.0.3:5061) Ended 2008-10-15 07:29:32 [NOTICE] switch_core_session.c:835 switch_core_session_thread() Close Channel sofia/internal/1000@192.168.0.3:5061 [CS_HANGUP] I don't understand why .wav is not valid format, Someone please review this and suggest me the what exactly can fix this issue.
