The cool tech this week is Skype. It’s free and it works very well for internet based called (even Wifi). In the past I have used this as my companies primary phone system, you can get external numbers and all the features of voicemail and other business features. I’ve since moved to Dialpad for my primary business phone. But I still use Skype as a solution when I have international leads that want to talk via Skype and internally we use it for screen shares and quick phone calls. Skype is definitely should be something your business should consider.
