Hi, I have 2 Xperia 10 iii with different providers (aldi talk / T-D1). Both have the problem that sometimes I can’t dial from contacts app. i.e. if I click a number from telephone history or contact app it doesn’t dial. Sometimes it says “no network” but there is.
All this happens just sometimes. Mostly everything is just fine.
Flight mode on off doesn’t help but restart.
Anybody else can confirm this, or any tips / solutions?
did you try restarting voicecall-manager.service and/or ofono service?
$ systemctl --user --no-pager status voicecall-manager
r
● voicecall-manager.service - Voicecall manager
....
systemctl --no-pager status ofono
● ofono.service - Telephony service
no I didn’t. Doesn’t that automatically restart when I restart the device ?
they do restart if you restart your device. By restarting the services via systemctl maybe you could avoid reboot (there is also a voicecall-ui-prestart service maybe this one is related to the issue also)
^^ …where to find? It’s not in system helper settings. Restarting mobile internet through helper settings doesn’t work either.
via terminal:
systemctl --user restart voicecall-ui-prestart
(voicecall-manager would be
systemctl --user restart voicecall-manager
and for ofono:
systemctl restart ofono
(for this you have to enter pin code)
thanks a lot, but reboot seems more easy to me. Does anybody else has that issue too?
I can confirm that, sometimes i want to call, but the call doesn’t start. I realized sometimes you cannot call back from call history, but from contacts, and i also encountered the no network error. A restart usually solves the problem. But doesn’t seem the right way, thats a bug that should be ironed out! 
fully agree you shouldnt have to mess around with systemd on a phone but if you want to try if it actually helps (at least temporarily) you can use “toeterm” (not in jolla store, only in openrepos or this chum thingy) so you only have to input the command once as you can save it there for further usage
but not sure if this fixes the issue
Or use qcommand to save the command
I have similar issues on C2. Sometimes, I cannot call by clicking on phone number. What is worst, when the phone is in this state, it is not ringing or even not accesible for incomming calls.
Not related: due to this issue I restart phone when it seems that it is not working, however, this action usualy interferee with my other real-work activities and after I click reboot I many times forget to input PIN - which results in shutdown phone and then I really miss incoming calls 
I would appreciate an option to reset problematic service (do not know which one) without reboot.
It’s not only the C2, I had this issue last day on my X10 II
Unfortunately, I forgot to catch some logs.
I also suspect aSFOS / Ofono problem (as opposed to device specific). Maybe favoure by mobile operator/network infrastructure too, because not everyone has it - but that’s a long shot.
I have it on X10III no Volte active ( incompatible with the Free Mobile - French operator).
I correlate it (empirically) with two ‘patterns’:
Reboot fixes the condition. I didn’t have time to try service restarts, usually I discover its condition when I need to call so in a hurry.
I tend to say the situation degraded (happens more often ) with 5.0.0.68.
services like pusleaudio, ofono, droid-hal-init should restart via systemd if for some reason the running process gets killed (you can try yourself and use devel-su kill -9 ofono process, shortly afterwards ofono gets restarted. also oom_score_adj is -1000).
So maybe its related to some other service/process or ofono (or other related process) has some issue but wont crash (else systemd would restart the process)
I have this occasionally. When trying to call one zero duration out going call is added to history.
I also noticed that when call arrives pickin up asks if I want to pick other call which on hold or replace it.
You have the SFOS tools where you can restart the network connections, maybe this would already be enough
We do have the app “helper settings” . Could anybody add something that starts / stopps ofono or anything else that helps, as a turnaround as long as it’s going to be fixed ?
No. Didn’t work in my case as mentioned somewhere above.
Yes exactly a restart o-fono should do the trick, there are apps for that but why not offer it as a standard function
