ZoiPer is a softphone that many of our customers enjoy using. We like ZoiPer because it supports the ‘variable bit rate codec’ iLBC (an audio compression technique). This compression technique allows for better call quality when making calls over a suboptimal internet connection.

ZoiPer is available for use on Windows and Mac PC's as well as on iOS and Android smartphones. Follow the following steps to install and configure the ZoiPer Softphone on your PC. The screenshots were taken from a Mac. Settings on other devices should be similar.

You can download ZoiPer for Windows or Mac here.
