Many people and business owners in Singapore say that the voice quality on cloud VoIP is not as good as PSTN. Although it may be true during the early days of the technology, we have learned a lot about how to improve voice call quality of VoIP ever since it was established. In fact, most people would be surprised to know that the call they are in is routed through a cloud VoIP, since most communications operator make upgrades discreetly. Generally, the difference is almost unnoticeable at all.
Get the Numbers
Since the quality of a hosted pabx is affected by many different factors, the first thing you should do is to ensure that all metrics are measured. Although tools can be used after the system is installed, it makes sense to think about these factors when planning for your IP PBX telephone system. Some of the metrics to be measured include lag, jitter, burst density and the compression techniques, to name a few.
Understand Your Network
Measuring the metrics is not just bout installation of tools and making reports. When, where and how to use these tools is crucial and requires thorough understanding of the data network, the traffic and the business requirements to get the best results. The type of tools you need also depends on the question you want to answer—do you want t find out what causes the spikes in your bandwidth consumption or find ways to reduce lag? The more you understand your network, the more accurate the results will be.
Reduce Load at Peak Times
As more businesses and establishments in Singapore shift to hosted pabx, network congestion can be a cause of concern. If voice call quality drops during peak times of the day but connection is pretty steady, upgrading to a faster internet package may not be the ideal solution. Instead of restricting the number of calls with your hosted voice over internet protocol system from Singapore or pausing internet activities when someone needs to make a call, it would be a better solution to redistribute activities during non-peak hours. For example, perform backups and file syncing at night or early in the morning to minimize congestion.
Optimize QoS Settings
Proper setting of the QoS can significantly improve your pbx system’s voice call quality, since the correct settings will allow the hardware to prioritize voice calls over other types of traffic. However, most of the time, QoS is not properly configured. Generally, routers use First In First Out method when handling data packets, meaning voice packets are not given priority and resulting to missed or dropped packets. On the contrary, with proper QoS configuration, voice packets will be prioritized and be handled first before everything else.
Get Specialized Hardware
Sometimes, establishments are assured by VoIP vendors that they can use their existing equipment with pbx phone system. It is technically possible, but you cannot expect to get optimum voice call quality with such devices. If your business really needs to start implementing the new system, such approach is a good start up. However, even if it’s your quickest solution at first, it is highly recommended to upgrade hardware such as the routers and desk phones. No matter how advanced your setting and software are, it’s difficult to improve voice call quality on poor hardware.
Use Compression Software
Like any system that involves digital signals, IP PBX telephone system requires compression of data before it is sent, meaning it will have to eliminate excess data bits. There are two type of compression service: lossy compression, which eliminates all unnecessary information; and lossless compression which only gets rid of redundant bits. The former is ideal for audio conversations as it eliminates ambient noises and reduces amount of bandwidth used, but it can also make conversations unintelligible. If you find your software eliminating too much information that the mmessage is no longer understandable, look for a new compressor that retains larger portion of the original audio data. Lossless compression, on the other hand, is ideal if you intend to send text files as it preserves almost the entire information.
Feedback happens when your voice from the receiver’s speaker is picked up by that person’s mouthpiece and, therefore, travels back to your speaker. If left unchecked, you will drown out your voice, making calls difficult to understand. Though you can reduce possibility of feedback by lowering the volume of the speakers, the best solution is to use a low frequency VoIP phone. Getting a phone with low frequency ensures that your and your caller’s voices are the only audio that will be transmitted through the line and will only be transmitted once.
Get Faster Internet
While it’s true that slow internet is not always the reason for poor voice quality, it can sometimes be the root of the problem of degrading voice calls. Maybe your internet can efficiently support your operations a few years back, but as the business grows the needs of your business also grows. Business data networks carry an increasing volume of data, so it should also be expected that voice call quality reduces over time. It could simply be that your current internet connection is no longer capable of providing enough to meet your business’ demands.
Ensuring quality VoIP for your business in Singapore is no mystery—it’s science. When you know your needs and follow these practices, it will surely reduce the possibility of network problems in the first place. Therefore, you will spend less time troubleshooting problems and more time focusing on operations and increasing your business productivity.
