Essential Steps in Network Optimization for VoIP

A man puts his finger onto a major point of a network.

Essential Steps in Network Optimization for VoIP

With increasing number of businesses adopting Voice over Internet (VoIP) solutions, a stable and reliable Internet connection is required to get the most out of a VoIP service. Accidental network slowdowns due to poorly configured or under-performing network equipment may decrease voice quality. VoIP connections use the same line you use for transmitting data, so you need to optimize your network a bit. Network optimization for VoIP will ensure higher voice quality and better overall VoIP service.

Your Business Needs Stable WAN Connection

Network for VoIP optimization starts with the basics i.e. your wide area network (WAN). Many small and medium businesses make a mistake by adopting enterprise grade software without assessing the network capacity and available bandwidth.

By running multiple applications that need networking resources, you can drastically reduce the voice quality and data transfer rates of your VoIP connection. Check download and upload speeds and opt for business Internet starting at minimum speeds of 75 Mbps.

An average small enterprise should cope with 75 Mbps for about 20 VoIP connections. If you need more lines for voice, video, and data transfer over VoIP, then you should consider network bandwidth of 100 Mbps and 150 Mbps or even higher.

Modernize Your Network Infrastructure

Both on premise and cloud-based VoIP platforms require modern network equipment if you are to benefit from all the advanced features they provide. Many businesses fail to assess their networking infrastructure properly before switching to VoIP. This way, you risk nonperformance due to outdated equipment that is not fully compatible with the VoIP system or cannot perform at maximum output.

You should not replace your entire network infrastructure. Upgrade or replace only specific equipment that is vital for your VoIP to run fast and smoothly. Network optimization for VoIP should cover all business-critical points such as routers, switches, and other communication equipment.

Network Optimization for VoIP Using VLAN

Prioritization of your network traffic through a well-designed virtual local area network (VLAN) offers many advantages to businesses. A properly set VLAN will assign more bandwidth to resource-consuming apps such as video conferencing or multiple VoIP lines working simultaneously.

VLAN markedly improves latency and reduces the number of drop calls, thus enhancing the overall performance of your VoIP system. Furthermore, you can give higher priority to network ports being used by either VoIP apps or other software that needs more bandwidth to operate.

PoE and PoE+ Advantages

Power over Ethernet (PoE) is a core VoIP technology that enables powering devices through the same wire used for transmitting voice or data. That said, you need only a PoE-enabled network switch and UPS to secure the uninterrupted operation of your VoIP system.

Your plan for network optimization for VoIP should envisage installation of one or more PoE-enabled switches. This will make easier deployment of more wireless access points, IP cameras, phones, and other equipment. All these devices get and transmit power and data concurrently.

The next step is implementation of PoE+ switches that are able to provide up to 30 watts per port. PoE switches can produce maximum output of 15.4 watts. Thus, you can connect more devices to a single switch and build a complex VoIP system.


Optimizing your network for VoIP does not require huge but smart investment. Assess all components of the network infrastructure to decide which components to upgrade and which to replace. Invest in modern technology since hosted VoIP platforms are developing very fast. Also, deploy network components that offer highest possible reliability to maintain a high-performing VoIP system.
