Choosing a Server with VoIP.ms

VoIP.ms operates servers across North America and internationally. Pick the one closest to you.

🇨🇦 Français • 🇲🇽 Español

How to choose

Use the server geographically closest to your physical location. Closer servers mean lower latency, which translates to better call quality with less delay and echo. A server further away will still work, but proximity is the right starting point.

Your device registers to the chosen server as well as your DID (phone number). You will notice that your DID also has a Point of Presence (POP) setting. Both must be set to the same server. If they don't match, inbound calls will not reach your device. Set your DID Point of Presence under DID Numbers → Manage DIDs → Edit.

* About intl.voip.ms

intl.voip.ms is intended for organizations whose team members are spread across both North America and international locations. Unlike region-specific servers, it is not tied to a single geographic region, making it the right choice when all agents need to register to the same server regardless of where they are located.

Latency

Latency is the round-trip travel time of a data packet between your network and the VoIP.ms server, measured in milliseconds (ms). For voice calls, low latency means natural conversation with no noticeable delay. High latency causes the characteristic "talking over each other" effect.

Acceptable thresholds:

Under 150 ms: Good quality, delay is imperceptible
150–300 ms: Noticeable but tolerable
Over 300 ms: Unacceptable for voice calls

To measure latency to a server, ping its hostname from your computer or network:

ping atlanta.voip.ms

Run this for two or three candidate servers and pick the one with the lowest and most consistent response times. High variance (jitter) is as problematic as high latency. It causes choppy or robotic audio.

Latency is primarily determined by physical distance and your ISP's routing. If latency to the closest server is unexpectedly high, try the next nearest city. Your ISP may route traffic inefficiently to certain destinations.

-[http://www.voip.ms VoIP.ms] offers many different servers, but which one should you choose? To put it simple, you can use the server closest to your location. Although that doesn't mean that a server further from your location will not work accordingly. For example, if you are located in Chicago, but you wish to use our Washington server, you will usually get good results. This entirely depends on the path taken by your internet service provider among many other reasons. Although the right rule of thumb is to use the server closer to you.

-<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.
-Server list (same as the list above, but simplified for easier copy/paste into the tool):

-= 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.
