When you rely on your VoIP for business
communications, it is important to be able to fix certain issues
internally first, before calling for support. Reliance on tech
support for some VoIP issues that you can handle yourself can make
you lose hours, if not days.
Here's a quick guide to help you.
Echo. Echo
is an easy-to-fix VoIP problem when you know what causes the echo
that you're dealing with. It could be any of these three: acoustic,
electromagnetic disruption and equipment.
If
it's an acoustic problem, you would just need to reduce the volume of
your speakers or earpiece. You can tell that it's an acoustic echo
simply by covering the mouthpiece. If it reduces the echo, then
you've found your problem.
Electromagnetic
disruption, on the other hand, is caused by equipment that's too near
to your phone. To see if this is the cause of your VoIP echo, try to
move your phone away. Did the echo disappear? If so, to solve your
problem, you just need to move your phone away from typical sources
of interference, such as your computer and router.
If
all else fails, there is likely a problem with your equipment. You
can check by switching phones. If there's no echo when you use a
different phone, then you should just replace the one you're
currently using.
Bandwidth.
Bandwidth is somehow a general problem in VoIP. Insufficient
bandwidth can cause a number of problems – we will mention some of
these later.
A way
to diagnose bandwidth problems is to check out your setup. Do you
experience call problems when you are running other programs that eat
a lot of bandwidth, such as gaming? Are there other computers
connected to your network when you experience problems?
The
first thing to do is to turn off and disconnect everything else. You
are testing for bandwidth problems here so you need to isolate the
issue. Disconnect all connecting computers. Close all other
applications that use up bandwidth. Does this make your calls sound
better?
If
so, then, the problem really does have something to do with your
bandwidth. You can implement a stopgap solution at the start. Here,
you need to configure your router's QoS so that you prioritize voice
and video applications. Voice apps, of course, pertain to programs
that you use for VoIP. Video, on the other, is for when you use video
conferencing. This may be optional if you don't really use that
feature.
Eventually,
especially if you use VoIP for business, you will need to upgrade
your bandwidth allotment or dedicate a separate network service for
your VoIP. It is problematic to have to contend with bandwidth
issues. As a technology, VoIP will really eat up bandwidth. You have
to be prepared for this from the get-go.
Choppy Voice. Choppy
voice is one of the bandwidth issues that we mentioned earlier. You
need to deal with this similarly as the above mentioned. If
reconfiguring the QoS does not work, then you will need to check with
your network administrator. There might be incompatibilities in how
you're set up.
Jitter and Jitter Buffer. Jitter
and jitter buffer are VoIP staples. Regardless of the quality of your
network and VoIP service provider, jitter and jitter buffer will
always be a factor in how your VoIP works.
Jitter
is the different pacing of how packets arrive to the receiver. This
is a natural occurrence. To make up for it and ensure that
conversations can be understood, the jitter buffer gets to work. The
buffer holds the voice packets before releasing them at a controlled
pace. This is where problems might occur.
It could be that your jitter buffer is
configured incorrectly. This will cause poor call quality and packet
loss. If your buffer is too small, there's not enough to retain
packets up until they can be released at an even pace. So, packets
may be dropped. If it is too big, packet delivery may be delayed.
You can address these problems by
configuring your dynamic jitter buffer. There is a static jitter
buffer built into your router – you cannot change this. But you can
configure the dynamic one via the software control panel. Ideally,
the buffer depth should be at 30 to 50 milliseconds.
Monitor Your VoIP. If
there's one major takeaway here, it's that you need to monitor your
VoIP 24/7. For businesses that rely on VoIP communications, this is an
imperative. Services of companies, like VoIP Spear, will test your
VoIP quality round-the-clock. This means that you are on top of
issues right away. You can do something about it, or you can decide
to forward the matter to tech support.
