How: test my VoIP connection

VoIP service quality depends on the effectiveness of your connection.

There are a number of Web sites, the performance of the connection is the measure so that you evaluate whether your line of your ISP's recommended requirements. You must determine the amount of the available bandwidth on your connection and data packet transmission speed on your ISP VoIP gateway. To test your connection, check your VoIP service provider site first to see what your needs are. Difficulty: easy

Instructions

1. 1

   Find a test range on the website.

Bandwidth is the number sent over the Internet. It is measured in bits per second (FPS). Place test bandwidth, see the results in kbit / S (kilobits per second) or Mbit / S (megabits per second). It is a thousand and a million bits per second, respectively. The results show the rate the download and the download speed. VoIP service provider, the download rate is important. Compare this rate with the requirements specified by your VoIP service provider.

2

Call troubleshooting your VoIP provider to get the IP address of the gateway forwarded calls.

All computers have a program called Ping tests the performance of network connections. You find from the "Run" option do your folder "Accessories" in your "Start" menu, type "Cmd" (without the quotation marks) and press "enter". This opens a window with the operating system command prompt. Type "ping < IP address > n 100 (without the square brackets or the gui)." (Llemets).

3

Watch the output of the Ping program on the Bil

dschirm. The program sends 100 packets to the IP address of the gateway indicating the results of each transmission. At the end of the race, ping displays a summary execution. Search for "" approximate round trip times in milliseconds. "" In this article, the specified maximum length should be less than 150.

4

Calculate the variability of the package arrival time.

Subtract the minimum time for a roundtrip ticket the day maximum round-trip. This gap of 4 for estimating the jitter. "Jitter" describes the defect in time arrival packet. It can cause damage to the sound quality and delays on the line. This device should be less than 2 MS (milliseconds).

5

The rate see the summary of ping, of overall loss to find.

Lost packets must number which data will come at the end. Therefore, packet loss must be close to zero as possible. Call quality will be much worse if the rate of loss is greater than 0.5%. If it is greater than 1%, the calls will be deleted.
