Zoiper

zoiper01Zoiper is a desktop and mobile SIP softphone developed by a company called Securax LTD. It is available for Android phones and tables, Apple phones and tablets, Windows, OSX, Linux, and more. It can be configured to work with a variety of services, including Ringfree’s VoIP telephone service. Zoiper is free to download and use.

Because Zoiper is not a Ringfree product, we’re limited in the degree of support we can offer for it, however we’re happy to provide setup assistance. Zoiper offers limited free technical support and has several tiers of premium support plans. For more information click here.

It’s important to know that if you have Ringfree telephone service, you have an extension within your phone system. In order to prevent conflicts between Zoiper (or another softphone) and your desk phone, a clone of your extension will need to be created. To create the cloned extension, simply contact Ringfree’s technical support.

It’s also worth noting that some cellular carriers, notably Verizon, block SIP traffic on the default port used by Zoiper and other softphones. This effects softphone use on the carrier’s mobile data network but has no effect while using a WiFi connection. To circumvent this, Ringfree will need to open an auxiliary port for SIP traffic. Please indicate your cellular carrier when communicating with Ringfree’s technical support.

In the field labeled Username, please enter the number of the extension you would like associated with your Zoiper installation. Normally this will be the cloned extension mentioned above rather than your normal extension number.
