Good Morning. I have the iPhone 6 Plus and i enabled the VOLTE service and am able to place HD calls to another user on my plan (Galaxy S5) but, i am not able to do the voice call. On my iPhone it does not give me the option to turn the call into a video chat, and on the Galaxy S5 the options are present but when selected it will say that the other party (Me) is not available for video calling. Help please? Is this option not available for the new iPhones yet?
