If you are using Voice over Internet Protocol phone system, you might probably have experienced poor voice call quality. Fortunately, the causes of poor VoIP audio are easy to diagnose and solve. Your Voice over IP service provider should be able to detect the problem and work with you to correct these issues. Some of the reasons that could be affecting the voice quality of your VoIP are the following:
1. Saturated Internet Connection
The internet connection always is the top factor affecting the voice quality of your voice over IP. Your bandwidth is the key for good quality audio. For example, if you have dial-up connection, do not expect excellent quality. A broadband connection works well, as long as it is not shared with too many users and communication applications.
2. Slow Internet Connection
Because voice over IP relies so much on the internet to make and take calls, the speed of the internet is crucial in ensuring quality voice calls. If you are using an outdated dial-up internet connection or a USB wireless modem with limited internet speed, expect your voice call quality to be less than spectacular.
3. Delayed Arrival of Voice Packets
This is a common issue of packet switched networks or wireless networks. Since the voice packets are divided into several packets, every packet may travel in different paths from the sender to the recipient. When these packets arrive at their destination in different order, the result is a voice call with poor audio quality. To solve this, use a jitter buffer, which collects, stores and sends voice packets in evenly spaced intervals—therefore, resulting to better voice call quality.
4. Poor-Quality Equipment
The hardware you use for your phone system greatly impacts the quality of your voice calls. Poor quality equipment are usually the cheapest (though not always!). It is, therefore, very imperative to look for an ATA, a router or an IP phone that offers great value for its price. When shopping for VoIP hardware, make sure to do a lot of research and talk to a reputed service provider, such as www.crystalvoice.com.sg in Singapore.
5. Prioritization of VoIP Traffic
Latency, also known as the lag in voice call, is a common and a major issue in Voice over IP. Latency is the amount of time it takes for the words to exit from the speaker’s mouth and reach the receiver’s end. This issue can be avoided by prioritizing voice over IP traffic over the network. Policy-based network management, Type of Service, Class of Service, bandwidth reservation, and Multi-Protocol Label Switching can all be used to prioritize voice over IP traffic. Using a good quality router can resolve this problem and will lead to business quality VoIP service.
6. Phone Frequencies
Your IP phone’s frequency may interfere with your other IP equipment. There are so many instances when people using 5.8 GHz phones experience getting quality voice call problems. When you have tried every solution possible and still cannot get a clear and stable voice call quality, try switching to a phone with lower frequency to solve the issue.
7. Terrible Weather Condition
Many times, voice calls are distorted by static, which is generated on network lines because of heavy rain strong winds, thunderstorms and electrical impulses. This static is discreet and often goes unnoticeable when surfing the internet or downloading files, which is why we do not complain when using the internet despite the terrible weather. But when you’re taking or making a call, the distorted voice quality becomes obvious and annoying. Luckily, it’s simple to fix static problem: simply unplug your router or your phone and then plug it back in.
8. Inadequate Router
Many establishments here in Singapore utilize the internet for both data and voice calls. There is absolutely nothing wrong with this as long as your router has the ability to prioritize voice over IP traffic. Without a router that can perform packet prioritization, voice call quality can be affected by other users in the same network. For instance, if taking a call, another user in the same network downloads a large file, without IP prioritization, the call would be degraded. A voice over IP router avoids this circumstance from happening by prioritizing voice traffic in your network.
9. Location of Hardware
Interference is a recipe for disaster to call quality during voice calls. Oftentimes, IP equipment interfere with each other, thus producing poor-quality voice call. For example, if the router sits too close to your ATA, you may experience issues in the quality of voice calls due to electricity feedback. Try transferring one of them somewhere far from the other to eliminate the echoes, garbled calls, dropped calls, etc.
10. The Codec Used
Voice over IP transfers data packets in compressed form, so the load transferred is lighter. The software used to compress the packets is called codecs. However, every codec is designed for a specific purpose. If a codec is created for communication, using it other than its purpose will sacrifice quality. An evident solution, use the right codec for your VoIP calls.
How Vendors Can Help You with VoIP Calls Quality Issues
