No waiting tone/sound when calling and no busy tone/sound

REPRODUCIBILITY: Not sure how to reproduce unfortunately
OS VERSION: 4.6.0.15
HARDWARE: Xperia 10 III
UI LANGUAGE: Swedish
REGRESSION: Definitely appeared with the 4.6 version but not sure which one, I would put my bet on 4.6.0.13

DESCRIPTION:

Couldn’t find anybody mentioning these kind of problems on any other topic…

Waiting sound of unanswered call does not sound. I mean the long “tooooot … tooooooot” when you are waiting for the call to be answered. Then when call is answered the voice works both ways and we can speak. When the call is dropped, then there is a very short/fast “toot toot toot”.

Furthermore when I call somebody who is already speaking on the phone, then call ends immediately with fast “toot toot toot”. So it doesnt allow me to hang on the line to wait for the other one to end the previous call.

PRECONDITIONS:

I flashed this phone with 4.4. a year ago and kept using and upgrading (now at version 4.6.0.15).

STEPS TO REPRODUCE:

I have no clues to share. Just normal usage of phone, calendar, Whisperfish/Signal, Pure Maps and so on.
Resetting sound subsystem via Settings > Utilities > Restart audio subsystem = does not help.
Hard reset of audio via phone shutdown > pressing volume up+down and power buttons > 3x vibration = does not help.

EXPECTED RESULT:

Waiting tone when waiting that the other one accepts the call.
Busy tone when the other one is having already a call.

ACTUAL RESULT:

No waiting tone - just silence - until the other one picks up the call.
When other one is busy - very fast “toot toot toot” and call ends immediately.

MODIFICATIONS:

No mods whatsoever

ADDITIONAL INFORMATION:

Reflash would help?

Pretty sure this is a general VoLTE(-on-SFOS) problem, and already reported.

Yes, this is related to VoLTE. When I do a call using VoLTE (on Swisscom), there is no ring tone, no nothing. A bit irritating but a minor issue. When using 3G or 2G (especially when roaming), I have a ring tone like it used to be.

Oh yes, indeed. I have the luxury to switch off VoLTE here and still make calls (Finland, 2G alive I guess…)
And indeed problems vanishes when VoLTE not on.
