Bria is the commercial version of X-Lite, Counterpath's free softphone.
X-Lite is identical to Bria in every way, except that Bria adds call transfer functionality, and you can add more than one SIP account to your configuration.
You can download and/or buy either from HERE.
As a result of how similar they are, we'll use X-Lite as the model for this guide.
IMPORTANT NOTE: It's extremely important you follow this guide for optimum settings and performance, as X-Lite is notoriously slow when registering to SIP servers using their default methods.
When you first start X-Lite, you'll notice that it has no SIP accounts enabled.
