| - | = Latency Testing Scripts (User Submitted) =
| |
| - | <p>All the following scripts were produced by voip.ms users who felt others might also benefit from the output of their efforts. They were written over a span of Years and probably need adjusting before you use them, to cater for changes in servers over time and changes in policies (like not testing heavily subscribed servers which are not open to new registrations)</p>
| |
| - | <p>If you aren't satisfied that the scripts are safe or simply don’t like the way they syntactically appear, you can still manually ping a selection of servers and choose a server based on the best latency. The following scripts are essentially just wrappers around the ping command which support lists of servers to feed to ping and present the output in a readable format.</p>
| |
| - | <p>If you feel you have a simpler cleaner script that works for another platform or language, please do add it to this wiki via a support ticket.

| - | === Using PingInfoView (Freeware, Windows Only) ===
| |
| - | PingInfoView is a tool that allows you to ping multiple servers at once which can be quite useful given the extended list of servers provided by Voip.ms. The tool can be found [https://www.nirsoft.net/utils/multiple_ping_tool.html here] (no affiliation with the author or voip.ms; direct download link [https://www.nirsoft.net/utils/pinginfoview.zip here]) and requires no installation, you can execute it directly from the zip file.

| | = Latency and its importance = | | = Latency and its importance = |
Latency is very important for Voip, this will determine the time that will take for the data package transmission to reach the destination. A high latency will lead to a delay and echoes in the communication.
Latency is measured in milliseconds (ms) For example: a latency of 150ms is barely noticeable, thus acceptable. Higher than that, quality starts to suffer. When it gets higher than 300 ms, it becomes unacceptable.
