We recommend CounterPath's X-Lite softphone.  
However, you will need to contact them directly as they are a 3rd party supplier and we can only offer limited support with this software.


You can download the X-Lite softphone for FREE at the following links, choose the one relevant for your computer i.e. PC or Mac versions.


Please be sure to use the links we suggest here rather than others you may see elsewhere as there a different versions of softphones and you need the VoIP versions for them to work with our system.
