Now we know what VoIP is, what's the benefit and purpose of VoIP protocol,
and how it's the basis of many platforms and applications, let's discuss the
challenges of using VoIP protocol. There is a complete dependency on
internet connectivity for VoIP calls to work. VoIP systems rely on a stable
internet connection to function properly.
If the internet connection is lost, VoIP calls may not be possible.
For example,
if you experience even a power outage and lose your internet connection, or
if there is any issue with the internet service provider,
you will not be able to make or receive VoIP calls. Many organizations
still keep a few traditional phone lines as a backup.
Then you have another important factor, which is the Quality of
Service, QoS. The quality of VoIP calls can be affected by various
factors, such as network congestion, packet loss,
and Jitter. Now let's discuss about the network congestion.
It occurs when there is too much data traffic on a network and the
available bandwidth is not sufficient to handle it. This can result in
slower connection speeds and reduce performance,
affecting your VoIP calls The packet loss occurs when data packets sent
over a network are not received by the destination device.
This may occur due to a network congestion, interference, or other issues.
Packet loss can result in poor call quality, as a destination device may not
receive all of the audio data being transmitted, and the users will have a
bad time understanding each other over the calls.
Another part of the QoS is Jitter,
which is the variation in the time it takes for the data packets to be
transmitted over a network. It is typically measured in milliseconds. High
level of Jitter can cause audio quality problems, as a destination device may
receive packets out of order or with a delay,
which can result in choppy or distorted audio with frequent
interruptions. Another important factor worth considering is the
security of these VoIP calls. VoIP system may be vulnerable to
security threats such as hacking and spoofing.
For example,
one of your organization's high profile employee is on a
conference call with vendors and clients. Some intruders barged
into the conference call and listened to the confidential
information being discussed on that call. So securing the calls from unwanted attendees is very critical.
