[SR-Users] RTPEngine Recording does not work

[Mojtaba]

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:
