That behavior would indicate that VoLTE isn't working in your area at the moment. 

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

Yes, that is what the word "moment" in my response indicates, that it is not working now, it may have been working, but it isn't at the "moment".

 

There could be a problem with the 700MHz LTE transmitter on your nearby tower. That would cause VoLTE to fail. If the other LTE transmitter frequencies were still working, that you allow you to use 4G data, but not VoLTE.

Which model Samsung has your wife got?

 

You need to lodge a complaint with Telstra first before the TIO will look at it. And there is nothing that Telstra will pay for as you can still make and receive calls, so you technically haven't lost core functionality.

The same thing has been happening to me for over a week, nearly every call.  It cuts out with "this call cannot be connected please try the number again".  I notice it's when it switches from 4G to 3G.    Settings are 4G, VoLTE on so why is switching back to 3G when VoLTE on means it shouldn't?

Exactly!! Whyyy is it switching!! Ill tell u why i think...telstra told me they have de-commissioned there 3G network and 100% this is causing issues for them.

no-one has contacted me to help other than when i complained so i lodged a TIO (telecommunications industry ombudsman) formal complaint!

lets see them jump now!!

The 3G network isn't getting decomissioned until mid-2024, so that has nothing to do with the problems that you are experiencing.

 

Check the 4G settings on your phone. For VoLTE to work, it needs to be set to 4G voice and data (mind you, with the current version of iOS, it will cause your calls to fail when trying to use VoLTE anyway). Until Apple fixes iOS 13, you are better off switching off the VoLTE (and 4G voice option).
