Voice over Internet Protocol technology has been used for voice communications for about a decade. Until fairly recently, reliability and quality issues had a negative effect on the reputation of these systems, particularly as users compared the service to the impeccable clarity they were accustomed to on their landline phones.

These dark days are gone and improvements in quality have been huge. Nevertheless, it remains likely that anyone who regularly uses a VoIP phone service has experienced singapore telegram some instances of poor call quality. The good news is that the reasons behind these quality issues are generally quite easy to diagnose and put right. A good service provider will help you to get to the bottom of any problems you are experiencing and ensure that they don’t become on-going issues once they have been fixed. If this is not the case, you should be looking for a different service provider!

This article takes a look at some of the main factors that can affect voice quality, common problems experienced by VoIP users and what can be done to resolve them.


Your own internet connection and particularly the bandwidth available are always the main factors affecting voice quality. One would never expect to be able to get a good VoIP service with a dial-up connection, but most broadband connections should work well provided that they are not shared with too many different communications applications. However, as most ISPs are optimised for web surfing rather than the settings required to achieve high-quality voice calls, an internet connection that is good for most uses may still give a poor call quality. The transmission of voice packets needs different internet protocol settings to those that may be provided as standard. A business class high-speed connection will provide the best experience.

Equipment
The VoIP equipment that you use will have a significant impact on the voice call quality you can achieve. You need to invest in the right IP phone or ATA / router. The frequency of your IP phone can also cause interference, with lower frequency options (eg 2.4 GHz) often performing better than higher frequency. For ATA / routers you need to consider the codecs supported (compression technologies), echo cancellation and firewall / security support.
