Soft Phones

Counterpath X-Lite

CounterPath's X-Lite helps you seamlessly transition from a traditional phone environment into the world of Voice over IP. The latest release of X-Lite provides a completely redesigned interface that allows for a contact-centric or dialpad-centric user experience, or a combination of the two. X-Lite is one of the most popular free softphones available for download.

X-Lite has proven to be an excellent, easy to use softphone. Our experiences with this product have been enjoyable overall. The only down side of this softphone is that since it is free, there is no support provided by Counterpath. Instead, there is a public forum which can be used for troubleshooting.
