High-quality voice calls are the norm today but consistent quality does require some effort. One way to evaluate your VoIP capacity is using the Phone.com VOIP test (works best on Safari and Firefox). This tool lets you evaluate your network performance by simulating one, three, five or ten concurrent calls from your office to the
If you know that your ISP can sustain a certain speed, simply multiply the number of expected concurrent calls by 100 kbps. If you deal with an “up to” ISP, a good solution would be to add the safety margin mentioned above so that you can sustain the required bandwidth, even when your Internet service falters.
It helps to know how much bandwidth you really have. However, your Internet Service Provider (ISP) will probably only confirm what you signed up for, also known as the advertised “up to” value, as in “up to 50 Mbps” or “up to 150 Mbps.” The best way to determine your bandwidth, is to run a
The answer is simple and complex. VoIP services use a variety of codecs to compress and decompress voice data, allowing it to travel over the Internet efficiently. Phone.com uses codecs that require approximately 100 kilobits per second (kbps) traveling up from your phone line and down to your phone line per second for each call.
This document explains voice codec bandwidth calculations and features to modify or conserve bandwidth when Voice over IP (VoIP) is used. One of the most important factors to consider when you build packet voice networks is proper capacity planning. Within capacity planning, bandwidth calculation is an important factor to consider when you design and troubleshoot
