Zoiper is such a great cross-platform, multi-account program that it is slowly becoming our most used and most recommended softphone. You can download the latest version from their download page or, if using a smartphone, from where you normally download apps (Google Play, iTunes, etc).

When you subscribe to our services, we customarily send a Welcome Email with a special link to Zoiper, which allows you to configure your smartphone by simply taking a photo of their generated matrix. We do not make the password part of that install routine for privacy / security purposes, but once you enter it, you are all set. If, however, you would rather configure it manually, the guides below should help.

To setup Zoiper, you need the YourUserID, YourPassword and YourDomain, as explained in Setup. However, for your convenience, we are also providing a visual guide for the most used OSs.

NB: as with most other softphones, it may sometimes be that Zoiper does not allow incoming calls by default; you need to enable a special setting such as "enable presence", "force background" or sometimes "keep Wi-Fi alive" for that to work. In our visual guides that is generally presented as the last step.


You may follow this guide solely through a screenshot album.

When starting Zoiper, you will find in Dialer the message "not registered". 

If you are seeing exactly the message displayed above, you might be able to click on it and then on the check-mark to get it to register. If that does not work because of wrong credentials, or if the message is simply "not registered", meaning that no account has been registered, follow along. We are assuming you have already registered and activated an account with us.

To enter the credentials in Zoiper, you need to press Config, then Add account.

Since you already have an account with us, answer yes to the question below. 

Choose EZvoip when prompted, then enter the credentials you obtained from login or the Welcome Email, then click Save.

At this point, you may already start making outgoing calls, but before you do, we recommend a few small adjustments. Long click (click and hold) on EZvoip.

Choose Modify account in the context menu.

At this point you may modify the Host to a server geographically closer to you, such as Paris, London or Melbourne, depending on your location.

Change Caller ID to what you want to appear on the display of phones you are calling.

Check Enable on start so that you don't have to click the check-mark every time the program starts. If you have a phone number (DID) with us, be sure to check "Enable Presence", otherwise you might not receive incoming phone calls!

Leave only the uLaw and GSM codecs enabled. Alternatively, you may enable one single codec according to your needs - see our discussion.

If EZvoip does not appear registered, click the check-mark (V next to it).

If the message Account is ready does not appear, repeat the previous steps and pay attention to accuracy.

Now go back to the Dialer,

...and check your connection by dialing our Echo service. If there is no noticeable delay, you are all set. Congratulations!
