Major Upgrade: Integration With The Apple Phone App!
Useability of this app is greatly improved with CallKit integration! VoIP Hangout incoming calls are now practical. To make VoIP Hangout outgoing calls within Contacts, do a long press on either the Phone or Video button within the contact. Select the number prefaced with "Hangouts" to use Hangouts to call/video . Note that iOS remembers the last number/app you used this way and makes it the default for the button.
