Questions Before Upgrading

0 votes

I currently use the Zoiper (free version) on my Nexus 5X (Android 8) phone for making VoIP calls over 3G. It's working fine but I am considering to improve the call quality over 3G, hence upgrading. 

My questions are: 

1. Should I just purchase the G729 Codec using free version 

2. Upgrade to the Pro version: if yes, would it include G729 Codec 

3. Last, would G729 make a significant difference in the call quality - like better the quality by 20%-30%

The G729 codec is not part of either Gold or Zoiper Premium. It is always a separate in-app purchase.

The quality will not be better if you are comparing it a wideband codec such as Opus, however on low-bandwidth network it will certainly conserve you some bandwidth and if you are having issues such is "choppy" audio due to insufficient bandwidth, it may help due its high compression.

Thank you and appreciated. That explained it perfectly.
