Calling this number lets your SIP phone ring – anytime, anywhere.We have new features, including inbound service, unique telephone numbers, and voicemail. You may select the area code for your number or get a toll-free number, and anyone in the world, from any telephone, will be able to call you! When you are online, your computer will `ring` and when you are offline, your calls will be sent to voicemail.""It works . . ."We have downloaded and used this to call from Buenos Aires, Argentina to the US and Canada. It connects about 70% of the time but receiving incoming calls is still something we are working out with the Customer Service which is responsive at least. Will be a great service once they develop further. Will continue using in hopes of improvement.
