If you are thinking of deploying a Hosted VoIP or Hosted PBX system for your business, performing the following steps will help determine if your Internet service is adequate.
1. Ask your VoIP service provider whether they have experience with customers in your area using your ISP. Good service providers will be able to tell whether their customers are getting good results with certain ISPs.
2. Do not take your ISPs word for the speed they are delivering. In most cases, it will be less. Connect a PC as close as possible to your ISPs modem or router and go to http://myspeed.visualware.com/index.html to run a speed test. Write down your upload speed and your download speed. The lowest speed is the most important which usually is your upload speed.
3. Determine your desired number of concurrent voice calls. Take 75% of your lowest speed (upload or download) and divide by 35Kbps (typical size of a voice call using G.729 codec which most VoIP service providers use). If the result is greater than the number of concurrent calls then your speed is sufficient. Don’t forget that if your speed is measured in Mbps that 1 Mbps = 1,000 Kbps (0.1 Mbps = 100 kbps).
4. Test the quality of your Internet connection using the HostMyCalls ISP Packet Loss and Delay Test Tool. It is free to use and will take less than 30 seconds of your time to start monitoring your IP address. The HostMyCalls Test Tool specifically checks the Internet connection for packet loss and latency (delay). If excessive packet loss or delay is found, it will report whether these are happening at your location or within the network of the ISP.
If you learn that you have a quality ISP, you have sufficient speed to support the number of concurrent calls that you need and you have a reliable circuit, then your Internet connection is ready for Hosted VoIP.
Although a quality connection to the Internet is required, it is not the only thing you should think about when deploying a Hosted VoIP or Hosted PBX system for your business.
