Working VoLTE reports, share your experience

kristatos

@charly @messayisto Can you please add a bugreport for your devices for the problem with missing dial tone? I've already done a bugreport for the Volla22, but for your devices there are none. Hopefully this will prioritize this bug, as it's present in every(?) Volla device.

messayisto

@kristatos The bug is very inconsistent on my device, I dont know if I can reproduce it properly, but I will try. Can you give me the name of your bugreport, is it in gitlab?

@messayisto The bugreport for the Volla22 is linked in my above post.

@kristatos

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.

messayisto

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.

You mean VoLTE, I suppose ?
(because if VoLTE is VoIP, not all VoIP systems are VoLTE)

@libremax sorry yes, VoLTE I meant

I switched my Fairphone 4 to 24.04 for volte. When it works the calls work and the data connection remains working as well (e.g. hotspot). But overall it comes with quite a number of limitations:

no reconnect after loss of connection (e.g. going to a basement without reception)
volte breaks when connecting to a wifi network and does not reconnect when disabling wifi. But it keeps working when enabling or disabling the wlan hotspot
after any of these two events the status indicator sometimes shows the volte sign, but as soon as I make or receive a call it will drop back to 3g (for as long as that still works, my provider announced the shutdown).

yes, that's probably some signal that is not understood by the phone handler, to me it seems linked to the callee's cellular network as ringing works or not consistently, depending on the person I call.

I don't call many numbers, but no call ever had a ringtone. Neither mobile numbers nor fixed lines or the one international call

kristatos

@gpatel-fr For me it's the same like @gandalf said: There is no ringtone while dialing for every call I'm making. No matter if it's the same carrier, an other carrier or a fixed number. Even calling service numbers from my provider doesn't produce a ringtone.

@kristatos

I just did a few tests, here in France there is not much variety in primary networks, we have 4 providers: Orange (the most important, historical provider), SFR, Bouygues and Free (my provider).

As far as I can tell (I don't have thousands of numbers to call to do a proper statistic) calls toward Orange and SFR ring, calls toward Bouygues and Free don't. The fact that a number is fixed or mobile don't matter.
