Hi, all. Next configuration: " <extension name="record_3..16_digits" continue="true"> <condition field="${is_already_recording}" expression="^$"/> <condition field="destination_number" expression="^(\d{3,16})$"> <action application="set" data="RECORD_TITLE=Recording ${caller_id_name} ${caller_id_number} to ${destination_number} at ${strftime(%Y-%m-%d %H:%M)}"/> <action application="set" data="RECORD_COPYRIGHT=(c) 2013"/> <action application="set" data="RECORD_SOFTWARE=FreeSwitch"/> <action application="set" data="RECORD_ARTIST=FreeSwitch"/> <action application="set" data="RECORD_COMMENT=FreeSwitch"/> <action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/> <action application="set" data="RECORD_STEREO=true"/> <action application="export" data="ignore_early_media=true"/> <action application="export" data="execute_on_answer=record_session $${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${caller_id_name}_${caller_id_number}_2_${destination_number}.wav"/> <action application="export" data="is_already_recording=true"/> </condition> </extension> " results in some an incomprehensible result. C onversation b eing recorded twice in the same file. The first recording of the conversation played accelerated. The second recorded conversation played at normal speed. The replacement of <action application="export" data="execute_on_answer=record_session $${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${caller_id_name}_${caller_id_number}_2_${destination_number}.wav"/> to the following solved the problem : <action application="set" data="media_bug_answer_req=true"/> <action application="record_session" data="$${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${caller_id_name}_${caller_id_number}_2_${destination_number}.wav"/> Both these examples are from [ http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_record_session ]. So what is the difference between these options? Thanks for help. With best regards, Shumaev DA, KBR Ltd.
