I have the same. When I try it with an android (same operator sim and settings, same position) U get a ringback tone.
Meaning 2 Phones, one Android, one SFOS.
Same Operator (Telekom.de).
Calling from SFOS to Android: no ringback tone on the SFOS device
Calling from Android to SFOS: ringback tone on the Android device.
Maybe we can make a proper bug report from that post and have it in the correct place?
For now I changed the category into bugreport.
Just create a new post and fill in the bug report template
There are generally two ways (responses) in a SIP/VoIP/VoLTE setting with implications how the ringback tone is supposed to be generated when calling a remote party. One is “Session Progress” (including early media) which not only signals to the local device that something is happening on the other side but also provides the audio data stream that can be played to the user - the other is “Ringing” which just indicates that the remote phone is ringing but requires the local device to locally generate the appropriate tones itself. Maybe one of them is poorly implemented which could help explain why some people have issues with missing ringing indication and others don’t. (but that’s pure speculation)
For me it’s not 100%, but maybe 50%. Sometimes I hear the calling sound, sometimes I don’t. It seems to be dependant on who I call (callee’s operator?).
Her are my experiences.
It depends from network connection: 2g 3g ring back tone is ok because of no VOLTE is used for calling
4g no ring back tone when VOLTE is enabled
In summary it means no ring back tone with VOLTE.
My providers are Mobilcom (telekom) and Mobilcom (Vodafone) both from Germany.
I confirm this behavior. My provider is Telefonica Germany.
Xperia 10 II Volte enabled and in a range of lte signal. In my case I can hear the ring back tone if the other party do not have volte. If they also does have volte enabled, there is no tone.
Thanks for all the reports on this. I’ve created an internal report and tagged it as “tracked”. We’ll do my best to post back here if there are any updates to report on it.
@flypig is there an update on this issue?
I could get ringback back by disabling settings->mobile-network->4G-calls as described in this thread.
This solution does not work with providers that enforce VoLTE thus a full bugfix is still needed.
Hi @Andrwe. Thanks for asking and sorry that you’re still experiencing this. I’m afraid I can’t give an update as I no longer have access to the internal bug database. However, the fact that it’s still tagged as “tracked” rather than “fixed” would suggest that work on a fix still isn’t completed yet I’m afraid.
@jovirkku, would you be able to help here?
I don’t get the ringback tone (just silence) when I call someone who also is on a VoLTE / 4G network.
I get the tone when I call someone who is on 2G or 3G network, or if my phone gets dropped to 2G.
To recap, the tone is heard only if either of the parties ISN’T using VoLTE. If both parties use VoLTE, there’s just silence.
i’m also interested in a fix for this problem. Makes me crazy, not to hear a ringbacktone.
What’s even worse, it’s not just the normal ‘free’ tone but also busy tone and others (e.g. messages that the called party is currently busy and you should wait). You just don’t know what’s going on, all you get is silence until either someone picks up the call or it gets disconnected e.g. due to timeout.
I can also confirm this issue with VoLTE. Used to just disable it and make normal calls via GSM but now my operator in Sweden shut down the GSM (2G) network close to us and thus I need to use VoLTE to be able to make or receive calls at all.
FYI: you can still see on the screen if the receiver is busy, or the call can’t connect etc. even if the sound is disabled but it’s still very very annoying! There need to be ringback tones! Please make this a priority to fix in the next update Jolla!
any update on this?
At least for me it is still occurring with Xperia 10 III
4.5.0.25
This is one I’d like to also see fixed, As where I am 2g is already gone, and 3G is due to be shutdown in the coming months.
I have a Sony Experia 10 II (Sauna 4.6)
When I call a land line, no call back ring tone
When I call a cell Phone, get the call back ring tone
Is this because of VoLTE?
Same problem here, happened more often, which I guess will be because of increased VoLTE coverage.
Is this because of VoLTE?
Check it for you: switch it off and try it. On my Sony Xperia 10 II with Sailfish OS 4.6 I get a ringback tone with VoLTE switched off on the numbers where I get none.
