Again guys. The problem isn't related to VoLTE at all. Please stay on topic.

 

VoLTE has no effect on the cross-network calls at-least in Wellington and other places in NZ. I've also had my sister (in Auckland) complain that since my parents switched back to Spark calls have become very hard to hear them properly. All parties have newer devices and are all on VoLTE. Both my sister and I have iPhones also and we both have VoLTE enabled on our phones.

 

To really understand the problem you need a phone on either Spark or Vodafone and call somebody on 2degrees. It is super clear cross-network between Spark / Vodafone but to 2degrees it is terrible even with VoLTE. This problem is actually getting worse and not better. I think I am going to be forced off to Spark fully soon because of this.

 

I came across similar issue where I can't hear the person I'm talking too , they have iphone and also on Spark Network .  Now I have seen on android to android phone calling to Spark is good call quality. 

I don't know how many others are seeing similar issue . I think this is a 2 degrees side where issue is seen.  I'm thinking if this is not fixed say by next year then I will switch providers. 

I ca'nt pay if service is not good .
