InnoCaption is working hard to make calls more accessible, and we now have a feature called Add caller. This feature allows you to make three-way calls.
To Add a caller on an iPhone and Android Next Gen (New v4.0)
Open the InnoCaption app
Make a call using the keypad
Tap the icon with three vertical dots
Tap Add caller
Tap From contacts or Keypad
Select the contact or enter the desired number
Once the other party answers the call, your three-way call will be connected
