VOIP compatibility on Windows Phone 8.1

Question

We had a situation where we wanted to build Windows Phone app with minimum compatible version Windows Phone 8.1. It makes uses of VOIP calls over 3G / 4G and Wifi.

I am unable to find whether Windows Phone 8.1 has full support for VOIP calls or not. Can anyone redirect me to right documentation or guidance if WP8.1 supports VOIP?
