Hi all, I installed RTPEngine (Version: 6.4.0.0+0~mr6.4.0.0 git-master-4eb80da) in my VM machine (Debian GNU/Linux 8 (jessie), i also installed kamailio 5.1. In kamailio routes, i have: route { ... #rtpengine_manage("record-call") rtpengine_manage(); start_recording(); ... } Here is all other configuration files: In /etc/default/ngcp-rtpengine-daemon file: RUN_RTPENGINE=yes CONFIG_FILE=/etc/rtpengine/rtpengine.conf CONFIG_SECTION=rtpengine PIDFILE=/var/run/ngcp-rtpengine-daemon.pid MANAGE_IPTABLES=yes TABLE=0 In /etc/default/ngcp-rtpengine-recording-daemon file: RUN_RTPENGINE_RECORDING=yes CONFIG_FILE=/etc/rtpengine/rtpengine-recording.conf CONFIG_SECTION=rtpengine-recording PIDFILE=/var/run/ngcp-rtpengine-recording-daemon.pid MUST_NFS=no NFS_HOST=192.168.1.1 NFS_REMOTE_PATH=/var/recordings NFS_LOCAL_MOUNT=/var/lib/rtpengine-recording # must match output-dir if used NFS_OPTIONS=hard,intr,tcp In /etc/rtpengine/rtpengine.conf file: [rtpengine] table = 0 interface = 192.168.122.200 listen-ng = 127.0.0.1:2223 recording-dir = /var/spool/rtpengine/ recording-method = proc In [rtpengine-recording] table = 0 # output-storage = db (use default) # output-format = mp3 (use default) # output-mixed = 1 spool-dir = /var/spool/rtpengine/metadata output-dir = /var/spool/rtpengine/recording But the recording is not work, I have these issues in syslog: [1530178531.860171] INFO: [MWFhMWM4MmVhYjFmYjY3MzVlZDlmZWMyYjNmNGVhNmY.]: Received command 'start recording' from 127.0.0.1:38654 [1530178531.860191] NOTICE: [MWFhMWM4MmVhYjFmYjY3MzVlZDlmZWMyYjNmNGVhNmY.]: Turning on call recording.
