========================================
Hi Asus
I've been using Asus Phones from the past 8-10 yrs. Zenfone 2, 2 Max, 2 Selfie, 3 and now ROG 3.
none of the above mentioned devices ever got this feature or an Update enabling Video Calls Over VOLTE.
I Request Asus Officials to work on it and enable this very important feature to its every devices.
this feature is missing in all your devices.

The point is if Asus can fix this issue with just an OTA update then why can't they provide an update and close this Forum.
Also when zenfone 2,3,max were launched there were many phone competitors which were providing Native Video calling from dialer. When your customers are paying a big amount for your devices it Asus's responsibility to provide them as good support as possible.
