It seems Vodafone has quietly enabled 3G HD voice calls in India, at least in Delhi/NCR region. The Vodafone India site doesn't mention anything, however, I can see noticeable improvements in voice quality and reduction in background noise. After various teats, it looks like
1. Both phones should be on the Vodafone network
2. Both phones should be in a 3G coverage area
I tested this between a Lumia 830 and Lumia 730
