Isn’t VoIP call quality poor? Noooo, the call quality is awesome! In fact new clients often comment just how good the audio is. To help get the best performance from a sports car you need a good road surface. Great call quality requires a decent internet connection and a good VoIP provider. It doesn’t have to be a leased line or even fibre, it does however need to be reliable and provide enough bandwidth to cope with the desired amount of simultaneous calls. Here is how in 3 simple steps.
Choose your internet provider carefully
For occasional use a wholesale home provider is fine however if you are serious about call quality and you want to run your business from it, choose a robust, business provider. We have years of experience in connectivity and recommend Zen Internet. Never heard of them? They have consistently one awards for quality and service, check them out here.
Give VoIP calls room to play
It doesn’t matter how much bandwidth your internet connection has, if it is shared with other services then it is a good idea to prioritise the traffic flow. Why? When you are checking your email, browsing the web or posting on social media it doesn’t matter if there is a 1/2 second delay before something happens. VoIP uses Real Time Protocol (RTP), note the real time part. This means if there is an interruption in the internet connection during a call it will be noticeable in the audio quality. For instance if the connection is uploading large files to Dropbox, downloading an email attachment whilst using a streaming service such as Netflix may put the connection under too much load.
Do the maths for perfect VoIP calls
Before any installation of VoIP you must make sure there is enough bandwidth to go around. Run a speed test to see how fast your internet connection is. Results can vary depending on the website you use, we find the BT wholesale one fairly consistent, you can find it here. Now calculate 90-95% of the upload and download results, internet speed can fluctuate and this allows for some breathing space. A single voice call takes approximately 100KB of bandwidth. Now workout how many simultaneous calls you think you will need, be on the generous side here. If you think 10 calls could take place at any one time then you will need 10 x 100KB (1MB). To be on the safe side and if bandwidth is available then I would recommend doubling this to 2MB. Now subtract what you need for voice calls from the speed test (90-95%) and what you have left can be used for the remainder of internet traffic. With this recipe you will experience great call quality.
Speed test results = 48MB download 12MB upload.
Results at 90% = 43MB download 11MB upload (rounded)
10 x simultaneous calls required = 1MB, allow 2MB
Remainder of traffic allocation. 43MB-2MB = 41MB download. 11MB-2MB = 9MB upload.
