Working VoLTE reports, share your experience

I can say that it seems to depend on the person I call - or more probably the technology they are using. I suspect call tone is working when calling people connected via 2G but I can't prove it. I use a FP5 so this is not related to Volla.

I can say that there messages in the exchanged data blocks that are unknown from the UT telephony stack, but no idea if there are call tones indicators hidden in this mysterious data. Maybe just decoding and interpreting them could be enough. It seems likely because I can't see a reason why the cellular providers would not send the call info to UT phones specifically. But in the real world, things can sometimes get very complicated.

@kristatos sorry, was blind, will do it later.

Done. Although I honestly doubt that my observations here are helpful... But lets see.

Good evening

Thank you messayisto for the bug report.
I have tested VoLTE again lately. There is still no dial tone. The called one simply talks about.

Greetings

Hello, just here to report I have tested the Rabbit R1 in Canada on the koodo/telus network and can confirm VoLTE call and text both work for both dispatch and receiving. The only thing which does not seem to work is the signal bars indecator and I was unable to use any data on the 4G lines even after putting in my APN settings, I am hopefull its just a configuration problem and that I can solve it with apn though I have not figured out what yet.

From mark1250 in USA:

"I recently installed UT on my Nord N10 5g BE2026, and I am using a daily image which shows as 24.04-1.x (2026-02-17/2).

VoLTE works for me.

I'm using a Redpocket SIM on AT&T as my carrier."

Hmm. Perhaps wise to post here as well:
VoLTE working on Oneplus Nord N10, 20.04 OTA-12 RC-1.
Lucky Mobile under Bell network, Canada.
SMS working as normal.
MMS working as well or perhaps better than before. Fewer undownloadable messages, though this could yet be coincidence.

Hello forum,

I would like to give a little status update.
I am on the latest RC 24.04-1.2 and have a Volla X23 mobile phone.

VoLTE has been working for me for a long time. But the usage is not good.

Since it was available there has been no ringtone when dialing. So it's hardly usable.

A bug report was created weeks ago.

Many greetings
Charly

@libremax On the Nothing Phone (1) running Noble in India. VoLTE seems to be working on all 3 major services here (Those being Airtel, Jio and Vi) . I haven't really had any issues in the past month of using UT. SMS are instant too.
