Logging
Notes: Voipmonitor by default uses 'daemon' facility of syslog to store status messages. By default it is stored to /var/log/syslog(debian/ubuntu) or to /var/log/messages(centos/rh)
You can find useful to store status info from voipmonitor to different file:
For rsyslog use this in /etc/rsyslog.conf
if $programname == 'voipmonitor' and $syslogseverity <= '7' then /var/log/voipmon.log & ~
