Counterpath is without a doubt the leader in commercial soft phones. I’ve used numerous version of their products over the years, and found them to be robust & reliable. Thus the fact that they’re selling Bria 3.0 for Mac & Windows at a discount this weekend is worth a mention.
You’ll find Bria 3.0 is very capable, able to handle both HDVoice and video. It’s one of the test targets that I routinely use when evaluating new devices for SIP interoperability.
Around Pixel Power Bria is the soft phone of choice for our travelling sales staff. Of course, they offer Bria iPhone and Bria Android editions as well, making it a well rounded product family.
