Does VoIP Slow Down Your Business Internet?

“Depending on the choice you make in your VoIP communications, there may be some slowing in your Internet connection. However there are steps you can take to make this slowing as minimal as possible.

Here are the options you have for VoIP communication services:

You could purchase an IP Phone that resembles a normal phone or you can purchase an ATA, which allows you to plug in any normal phone and begin making calls.

You will also need to subscribe to a service provider who will make the connections through VoIP and your broadband connection for you.

The CODEC you decide you want to use for your VoIP service will also be a major factor on what bandwidth that will be taken up with your VoIP service. A smaller CODEC will run you about 30 MB where a larger one with is around 90 to 100 MB.

The way the VoIP works and why it affects the speed of your Internet connection is because the voice data, or packets will move along the existing network just as other data does. However, you can choose how high or low you want the affect to be on your Internet by asking the provider of your VoIP to up or down the quality to meet the needs of your broadband connectivity.

Some of the variables that take place in the quality and bandwidth use in your systems will work as follows:

  1. Latency- Latency describes the time that it takes for a packet to get from one location to another. Therefore, if there is too much traffic on the line, or if a voice packet becomes blocked behind a large data packet (that like an email attachment), the voice packet is likely going to be delayed to the point that the quality of the call is compromised. With this in mind, we know that the maximum amount of latency that a voice call can tolerate one way is between 100 and 150 milliseconds.
  1. Jitter- For the sound of the voice on a VoIP call to be intelligible, consecutive voice packets have to arrive at regular intervals. Jitter is the explanation of the degree of variability in packet reaching the set destination, which can be caused by bursts of data traffic or just too much traffic on the line. Voice packets can be at most around only 40 to 75 milliseconds of jitter delay.
  1. Packet loss- Finally the amount of packet loss is a common occurrence in traditional data networking systems; however, computers and applications are often designed to request a retransmission of lost packets. In the VoIP, however the process is to take the dropped voice packets and have them discarded, and not retransmitted. Voice traffic can tolerate less than a 1% to 3% for loss of packets before callers experience noticeable gaps in conversation.

When you consider the bandwidth usage, it is not directly proportional to the bit rate, and will depend on factors like the protocol that it is programmed to use. Each packet of voice data is contained within a UDP packet with headers and other information.

VoIP software or hardware may give you the option to specify which of the CODECS you want to implement for your VoIP service. This allows you to make a choice between voice quality and network bandwidth usage, which might be necessary if you want to allow multiple simultaneous calls to participate in using an ordinary broadband connection.

Designating the bandwidth priority use is also an important way to save as much bandwidth for the services you find most important. Quality is controlled with prioritization and the right Internet connection.”
