Does Every VoiP Provider Have the Same Quality of Service?

Unified Communications, or UC, platforms have been adopted by many organizations in recent years. A UC is the integration of all digital communications traffic, data and VoIP for businesses, over a single physical network. This is made possible by various software applications.

IT must carefully manage traffic response times, especially for real-time voice and video applications, to ensure an optimal experience for all users. This is usually accomplished through the creation and management of Quality of Service protocols.

What is Quality of Service?

Quality of Service, typically shortened to QoS, is the assessment of a network service’s complete performance. Oftentimes, it is gauged from the end-user’s perspective and how they feel about the level of service they are receiving.

What is Measured?

The opinions of users is the most important metric. If VoIP calls are constantly breaking up and having gaps, then that’s an issue. Poor VoIP performance can be caused by packet loss, latency, and jitter during periods of high network traffic.

Packet Loss

Packet loss is when some packets don’t make it to the intended destination. In VoIP, speech is digitized and put into packets for transmission over a network connection between speakers. If any of these transmissions are lost, the receiver won’t get the message as intended.


Latency is the amount of time a packet takes to travel from the sender to the receiver. Low latency and equal latency for all packets is essential for good QoS. Because different packets can take different routes, this can be difficult to achieve, and many QoS devices such as switches buffer VoIP packets to maintain the order of the packets.


To maintain a good level of voice quality, VoIP packets need to be sent in an unbroken stream from the sender to the receiver. If there is congestion at any point on the network, it can cause gaps or Interruptions in this stream which affects audio quality – this is Jitter.

VoIP Service Suppliers and QoS

It’s crucial to comprehend that not all VoIP service providers are created equal. They offer various levels of services at diverse price points and have distinct methods of handling customer QoS issues. In other words, the answer to the question “Is QoS the Same in Every VoIP Provider” is no.

The agreement between you and the service supplier should stipulate regular review meetings to discuss recent performance, identify any issues (present or future), and agree on steps for resolution. VoIP infrastructure updates (both software and hardware) are inevitable from time to time; these need to be planned in advance.

Another crucial thing to remember is that not every device is VoIP-compatible and will still require a connection to the old network. If it’s not configured correctly, your voIP could have issues. To put it simply, VoIP for business should be seen as a high-quality way of networking that is integral to your company’s strategy. Because first impressions are key, lackluster performance from VOIP can reflect poorly on your organization as a whole.

3 Common VoIP Issues and How to Fix Them

Many organizations have moved to an Integrated Communications Strategy, which usually includes VoIP. The benefits of this voice-over internet protocol usually include cheaper long-distance and international calling rates, improved customer relations, and better performance in the workplace.

Although VoIP comes with a range of benefits, it must be properly implemented and managed to avoid problems. Here are some common issues you may come across if VoIP isn’t used correctly.

Routers and Switches

If your VoIP system isn’t working properly, it could be due to a problem with your router or switch. Make sure that they’re configured correctly to support VoIP, and check for any updates that might have affected the configuration. Also, make sure that the ports on your switch are configured to support VLANs.

Older routers that are not up-to-date with the latest software might cause compatibility problems and decreased performance. If you’re experiencing VoIP issues, try resetting your router. There’s no guarantee it will work, but it’s worth a shot.


If you want optimal VoIP performance, then you need to have enough bandwidth. Try to avoid having continuous network congestion. If the problem only happens sometimes, see which application or service requires a lot of bandwidth during those times.

You should have bandwidth monitoring on your normal network management tasklist, so issues with insufficient or poor quality connectivity can be identified and dealt with quickly. However, sometimes a network issue is beyond your control – it might be caused by factors at your ISP (Internet Service Provider), for example.

Desktop Problems

Echo — This is one of the most common VoIP issues. It’s created when the handset volume is set too high and the microphone hears the incoming call from the earpiece, and then rebroadcasts it.

The most common solution is to lower the volume on both ends. However, this doesn’t always work, and another option is to use a headset. But even headsets have their own set of problems, like ergonomics since they can be worn for long periods of time.

Training — A possibility is that the problem lies in user training—or lack thereof. “It’s just a phone” has been used as an reason to skimp on training budget, but VoIP systems are complex and comprehensive solutions. Therefore, proper education is key to taking advantage of all benefits.
