Voice over Internet Protocol (VoIP) uses data packets to transmit voice calls digitally over the internet and delivers excellent performance, as long as the network is set up to accommodate our needs. 

Internet speed, routing equipment, and data network configuration are crucial factors in getting the best VoIP service for companies. So what are some tips to optimize VoIP with network monitoring? Find out below. 

What is VoIP?

VoIP uses the internet to make voice calls, instead of using the traditional copper wire network used by standard telephone lines. To make a VoIP call, we must first connect our phone device to the web via Wi-Fi or ethernet cable. On a mobile phone, we can open a VoIP app and connect it to a Wi-Fi network or to 4G or 5G services. 

When we dial a number, a VoIP service provider organizes the call. The service will then convert our voice and the voice of the person we’re talking to into small data packets, similar to the way pages on websites and online videos are transmitted. Our phone and the person we’re calling then convert these packets into audible sound. VoIP calls are capable of reaching any number around the world, whether you’re calling a standard phone number or a mobile phone. 

How to Optimize Network for VoIP

VoIP performance relies heavily on the internet. To optimize your company’s setup for VoIP calls, the recommendations below can be tried:

1. Check Connection

To check the connection, do the following steps:

  • Make sure the connection is suitable

VoIP traffic puts extra demands on the internet connection. If the company uses the phone frequently to connect with clients and customers, as well as to organize internal work, it can cause network congestion. If you are already connected, run a VoIP speed test to check how fast the connection is in the office. 

  • Diagnose the problem

The speed test will show how well the current network connection handles the 4 key elements required for a VoIP connection. These four are:

  • Latency: determines how long it takes for data packets to arrive.
  • Jitter: how consistent the latency is across the enterprise line.
  • Speed: how much data can be sent or received with an internet connection.
  • Packet Loss: the amount of data packets that never arrive.
  • Upgrade If Necessary

If the connection speed test results turn out to be poor, first inform the internet service provider that the company uses. If the current service provider is unable to help, then it is advisable to look for another internet provider. 

It is recommended to have a bandwidth of at least 100 Kbps so that there is enough space on the network for normal internet traffic and VoIP. If possible, opt for fiber optic internet over cable internet. 

Additionally, VoIP requires a maximum latency of 250 milliseconds, if possible less than that for best results. If the latency is more than that, then the call quality will most likely stutter, and the connection may even drop.

2. Use the Right Devices

The following are some of the equipment needed for VoIP:

  • Networking Tools

If the age of the router used by the company is more than 3 years old, then it’s time to replace it. The performance of the new router will be much better. Try to find routers and switchers that are compatible with Quality of Service (Q0S). Routers with Wi-Fi 5 and Wi-Fi 6 have faster connections and better security. Tri-band routers are recommended over one band or two band. 

  • Wired

Modern Wi-Fi connections are more stable, but ethernet is better. Standard VoIP phones in enterprises are usually recommended to use CAT6 or CAT7. CAT8 also exists, but this is usually used by companies that require a very large amount of bandwidth. Meanwhile, micro and small companies should only use CAT6 and CAT7. 

  • VoIP Handset

Handsets or telephone sets for VoIP are currently available in a wide variety. To choose one, it actually depends on your own preferences and needs. We can choose from a standard display with a cellphone-style display type, or a tablet with a base station. 

  • Firewall & Antivirus Software

Every company needs firewall and antivirus software to protect the wider network and better VoIP connection, as well as to handle cyber attacks. Find the firewall and antivirus software service that best suits your company’s needs. 

3. Create a VLAN

Corporate computer networks use a local area network (LAN). While VLANs are LANs that are above and within our LAN network. If you want the best VoIP connection, it is recommended to create a VLAN that gives the highest broadcast priority to voice packets. 

It is recommended to use a business-class router with QoS features and pair it with a manageable switch or smart switch. Then create VLANs with separate Dynamic Host Configuration Protocol (DHCP) ranges, and apply them to switching to specific ports. Give high priority to ports used for VoIP lines. Invest in a switch with high gigabit ports and auto-configuration that adjusts to the QoS for each phone. 

4. Invest in Power over Ethernet (PoE)

Wouldn’t it be more helpful and practical if we didn’t have to find an electrical connection to power every VoIP device used in the company? That’s why it’s important to use a Power over Ethernet (PoE) switch with UPS backup power in the company. With this setup, even if the power is out, the VoIP system will still have power. 

All VoIP devices connected to PoE such as wireless access points, security card readers, and intercoms will remain on. That way, even during a power outage, company productivity does not have to stop completely. Some activities can still be carried out while waiting for normal electricity to return. 

Regular PoE switches can deliver a maximum output of up to 15.4 watts, while smart business-class PoE+ switches offer up to 30 watts of output per port. This means that each switch can deliver power to more connections. Some VoIP calls require more power, especially those with cameras or video displays. 

Make sure to first check the maximum power required by the company’s phones and the minimum power budget of the switch. The consumption of phones or other powered devices should be less compared to the switching budget. Every company needs reliable network monitoring for better connection and performance.
