Mission-critical application
Often,
a
VPN
connection
is
a
mission-critical
application
for
exchanging
data
between
Head
and
Branch offices.
This
mission-critical
application
must
be
connected
smoothly,
without
any
dropping.
To
ensure
this,
you should
set
the
priority
to
the
high
level
to
preventing
any
other
applications
from
saturating
the
bandwidth.
Voice application
Voice
applications
are
latency-sensitive.
Most
VoIP
devices
use
the
SIP
protocol,
which
automatically assigns
a
port
number.
This
means
that
it
is
better
to
use
a
fixed
IP
address
to
catch
VoIP
packets
and rout
them
as
high
priority
traffic.
The
s
ettings
shown
above
will
help
to
improve
the
quality
of
your
VoIP
service
when
the
link
is
fully loaded.
