JustConnect! for Android
This APP is not only for Enterprise, but also for suitable for consumers who travel a lot or have some relatives and friends overseas. The calling function works perfectly when you have ok-to-use Internet. By using it, you will save a lot from international calls. P.S. need to subscribe the service from CHT Global first. Only installing the APP won't work.
Voice quality is pretty good. I use it for calls as my office line identity so I can be reached anywhere, whether via 3G/4G or WiFi, both domestically and abroad. Best part is others can contact me or I them through my domestic US number even when I am abroad! Corporate Employees are all preloaded into the APP and allows for easy calling and messaging.
