Factors That Affect the Voice Quality of Your VoIP Phone Calls

The dawn of technological advancements at this period in time has brought nothing but convenience to a lot of people. Gone were the days we solely relied on our telephone lines to make a call. Now, as long as you have a stable connection to the internet, you can call your loved one from countries away through a cloud VoIP service without the excess costs of using a local telephone.

A lot of businesses in Singapore are also adapting this system to cater the communication needs of their company. For one, it is far more preferable considering it saves a lot of operating costs which can be allocated to other urgent matters. Second, it’s also considered an efficient system of communicating with personnel regularly, no matter where they are headed to, so long as they are connected to the internet.

The deployment of this kind of system in most businesses is growing. With that, the complexities associated to its implementation also grew over time. One of the biggest concerns involving a VoIP system or a hosted pabx is the poor voice quality of calls from time to time.

This can be disadvantageous in the business world, where proper communication plays a crucial role in administering appropriate solutions. Utmost call quality is what is expected by enterprises and major businesses — leaving a lot of business owners still hesitant over the idea of transitioning to a pbx phone system, which traditionally makes use of VoIP as a communication channel.

A number of culprits affect voice quality in cloud VoIP conversations, some of which include jitter, latency, weak internet connection, and lost packets. Although a lot of improvements have been made with regards to the matter, there are other factors that also degrade or affect the voice quality in your VoIP conversations will be mentioned further in this article.


Perhaps one of the leading factors behind a poor voice quality of your VoIP conversations boils down to your internet connection. The bandwidth you have allotted for VoIP is the key if you want your IP PBX telephone system calls to flow smoothly. A simple broadband connection for the service with www.crystalvoice.com.sg from Singapore will work just fine, so long as it’s not frequently spotty and shared with a lot of other applications since it can eat a large portion of your bandwidth. If you have an unstable connection, chances are you will encounter issues and problems over time. VoIP mainly depends on your bandwidth hence you can either turn it into an advantage or a drawback.

Equipment Quality

Ensuring a good quality of your VoIP calls is also partly based on what VoIP equipment you use. There are a number of cases in Singapore where the cheapest devices turn out to be poor quality equipment, but of course not all. However, it is important to gain generous information regarding routers and IP phones before investing on it. Research online reviews or discussions of its specs. You have to ensure the hardware exactly matches what your company needs.

There are also cases where businesses still suffer frequent problems even with the use of best, high-quality devices. Why? They are not using the appropriate hardware to suit their needs. Which is why you have to carefully consider your circumstances in order to find a device that is fit for the needs of the business.

Weather Conditions

Voice quality of VoIP calls or a hosted pabx can also be terribly distorted by a small, static electricity produced within broadband lines because of heavy rain, thunderstorms, and sudden electrical impulses. This is commonly known as the ‘static’, and while it isn’t as noticeable as we browse through sites or even download files, it can be disturbing when listened to voice. To get rid of static, cautiously unplug your device whether it’s a phone or a router, and plug it right back again shortly.

Network Latency

Latency is brought about by the required distance the packet needs to travel, which can also be affected by unstable network conditions. While a pbx phone system is convenient in a sense that you can talk to anyone across the globe, there is a delay in the transfer of a packet when it covers a lot more distance such as in cases of intercontinental calls. Each packet needs a corresponding number of router hops to reach the intended destination, and if it requires a higher number of hops chances are it’ll be more delayed.


Ever wondered why there are frequent echoes induced at various points in your VoIP conversation? That is because of the conversion of IP media to digital/analog and vice versa. It can happen as soon as the caller’s voice is picked up by the microphone. Echoes are generally hard to monitor in an IP PBX telephone system, let alone contain. However, there are some vendors who provide modules on hardware and software echo cancellation at the gateway level where the translation of data happens. This is one parameter which can be adjusted accordingly through specialized tools.

Whether you decide to adapt a VoIP system or stick with the traditional phone system for your communication needs, there will always be concerns to address every now and then. There will be unforeseeable factors which can be a setback even if you choose the best device or bandwidth plan in Singapore. Regardless, there is an improvement in the quality of VoIP calls lately that is has become a preferable option for businesses. While there may be instances of problems in voice quality, the chances of them occurring are relatively low.
