If you’ve ever used a business phone system, chances are that you’ve used a VoIP PBX or IP PBX system at least once. There are many advantages of using VoIP PBX for your business, but like most applications that work over a network, they’re prone to performance issues if network problems arise.

In this article, we’re running you through how to monitor VoIP PBX systems to ensure optimal call quality with network monitoring.

What is VoIP PBX (or VoIP PBX Systems)?
What is VoIP PBX (or VoIP PBX Systems)?

VoIP PBX, also referred to as IP PBX, is a business phone system that uses internet protocol (IP) to transmit voice. It uses Internet protocol (IP) networks to transmit voice calls and other communication services and combines traditional Private Branch Exchange (PBX) functionality with the flexibility and cost-efficiency of VoIP technology.

In a traditional PBX system, analog or digital phone lines are used to transmit voice calls within an organization. However, a VoIP PBX system uses IP networks, such as the internet or a private intranet, to transmit voice calls as data packets.

With a VoIP PBX, voice calls are converted into digital packets and transmitted over the IP network. This allows for the integration of various communication services, such as voice calls, video calls, instant messaging, and presence information, into a single system. It also enables features like voicemail, call routing, call forwarding, and conference calling.

A VoIP PBX system can be hardware or software based, and works over a company’s LAN or WAN network, rather than through the circuit-switched networks used by the traditional Public Switched Telephone Network (PSTN). It can be hosted and operated locally, but can also be hosted somewhere else like SaaS Hosted PBX solutions.

They typically switch calls between VoIP on local lines or between VoIP and traditional telephone users in the same way a PBX does.

How Does Network Performance Affect VoIP PBX Systems?
How Does Network Performance Affect VoIP PBX Systems?

VoIP is sensitive to network performance, and can be impacted by network problems like packet loss, latency, and VoIP jitter.

When you make a VoIP call, the VoIP phone (software or hardware) usually communicates with the PBX system. So if your VoIP Quality is affected by poor network performance, your whole VoIP PBX System’s call quality will suffer. Here's how network performance can affect VoIP PBX systems:

  • Call Quality: Network performance directly impacts call quality in a VoIP PBX system. Voice data packets need to be transmitted in real-time, and any network issues such as high latency, jitter, or packet loss can result in degraded call quality. Delays or disruptions in packet delivery can lead to voice distortion, dropped calls, or voice delays, negatively impacting the user experience.
  • Call Reliability: A stable and robust network is essential for reliable call connections. If the network experiences frequent outages, interruptions, or high levels of congestion, it can lead to call drops, call failures, or an inability to establish calls altogether. Network performance issues can disrupt communication and hinder productivity within the organization.
  • Bandwidth Requirements: VoIP calls consume network bandwidth, and the available bandwidth must be sufficient to accommodate the voice traffic. Inadequate bandwidth can lead to congestion and bottlenecks, causing call quality issues and call drops. Network performance monitoring helps identify whether the available bandwidth is meeting the demands of the VoIP PBX system and enables capacity planning to ensure smooth operations.
  • QoS and Traffic Prioritization: QoS for VoIP mechanisms prioritize voice traffic over other data traffic on the network. Network performance affects the ability to implement QoS effectively. Without proper network performance, it may be challenging to prioritize VoIP traffic, resulting in increased latency, jitter, or packet loss, which can impact call quality and reliability.

Seeing as most VoIP PBX solutions are offered by Service Providers, when performance issues arise, customers will quickly run to their MSP for answers.

So MSPs need to be equipped with the right tools to proactively monitor VoIP PBX performance to quickly identify and troubleshoot performance issues affecting their customers as fast as possible.
