As more companies adopt Voice over Internet (VoIP)
solutions, they need a stable and reliable Internet connection to take full
advantage of VoIP services. Accidental deceleration of the network caused by
improperly configured network equipment or poor performance may result in poor
audio quality. The VoIP connection uses the same line used to transmit data, so
the network should be optimized slightly. The optimization of the VoIP network
improves voice quality and improves the overall VoIP service.
Keeping your network in respectable condition can be a
difficult particularly after determining to allow Voice over IP (VoIP) demands
on your network. These are the Essential steps to make a professional
network installation for VoIP.
- Determine
the type of call to be made
Before going into the details of the networks, you must
determine the devices that will make your employees make VoIP calls. You can
acquisition a committed VoIP phone that permits your employees to make and
receive requests from your desk. You can also make VoIP requests directly from
your computer without moving the real phone. You can also make a VoIP request from
your smartphone to take benefit of that practice. Decide which, if not all, of
these endpoints will be used immediately. Decide before the network needs more
reflection.
- Select
a power resource
The informal way to ensure that VoIP phones can receive
power is to assign the power cables over Ethernet (PoE). With PoE, devices that
are not associated to AC power can admission the Internet. Companies use PoE
for observation cameras, ceiling-mounted access points and even LED lights. If
your Ethernet change does not support PoE, you can appeal a PoE injector. PoE
injectors are additional power supplies that can be used with non-PoE switches.
- VoIP
network optimization using VLAN
Prioritizing network traffic over well-designed virtual
local area networks (VLANs) offers many benefits to businesses. Properly
configured VLANs will allocate more bandwidth to applications that consume
resources, such as video conferencing and multiple VoIP lines running simultaneously.
VLANs can significantly improve latency, reduce the amount
of missed calls and improve the overall performance of a VoIP system. In
addition, network ports used by VoIP applications or other software that
require more bandwidth to operate may have higher priority.
- Wireless
traffic management through transfer of access points.
Outdated Wi-Fi networks are typically small accomplished
systems intended for laptops and tablets, not for voice or video, we
recommends managed Wi-Fi to support the transfer of access points (APs) if the
network is overloaded as necessary
- Double-check Your Router
Check if your router has packet capacity per second (PPS).
This feature provides traffic modeling and surveillance. This allows you to
prioritize audio and video data on your network. "Basically, we assume
that one in five people will participate in a 1 Mbit / s [Mbps] voice call and
one in seven will participate in a 100 Mbit / s [video] conference." He
said. Multiply the number of voice users in the company that make voice and
video calls at some time and multiply that number by at least five. This is the
amount of traffic that the router can manage without problems.
- Prioritize, isolate and segment VoIP traffic by VLAN.
A variety of services running on the network can affect the
performance of bandwidth sensitive applications, such as video conferencing,
and applications that require priority, such as VoIP. To obtain the best
quality of service (QoS), segment your network with virtual local area networks
to ensure a voice-only bandwidth. VLANs allow you to prioritize data traffic
for network sensitive applications to improve performance and maintain QoS,
eliminating the need to worry about dropped calls, latency and phase
fluctuation.
Typically, network segmentation starts on the router, so
invest in a business-class router with QoS capabilities and combine it with a
managed or intelligent switch that provides other key features that will be
addressed later. Create VLANs using separate ranges of Dynamic Host
Configuration Protocol (DHCP) and apply them to switches on specific ports to
give higher priority to the ports used for VoIP lines. For switches, look for
hardware with high-performance gigabit ports and automatic configuration that
matches the QoS of each phone.
- Rate
your VPN to protect your phone
VoIP has been a standard for many years and, like many
mature technologies, when security was invented, security was not exactly what
I could think of. One of the key security issues for VoIP is the underlying
transport mechanism, the Session Initiated Protocol (SIP). There are several
ways to protect SIP, but one of the best is to simply encrypt the transmission
by running it on a virtual private network (VPN). However, while a single call
is relatively easy, talking about many phones in a business environment can
quickly become complicated. Evaluate the VPN solutions of the providers that
understand the requirements to protect VoIP traffic and test these solutions
under load to ensure that you do not increase security at the expense of call
quality.
Conclusion
Optimizing a network for VoIP requires a huge but smart
investment. Evaluate all components of the network infrastructure to determine
which components to update and which to replace. Invest in the latest
technology as hosted VoIP platforms develop very fast. It implements the most
reliable network components to maintain a high performance VoIP system.
