Is it ok? Is there something else you recommend instead? I tried nextcloud talk and it was pretty bad. Jitsi was ok but self hosting it looked complicated. FOSS only, of course.
I use Jami and love it. If you want to use it on a de-googled phone you may not get live notifications though, which is annoying if you want to use it for calls. The simplest solution is to allow it to run in the background but it also allows you to use selfhosted push notifications which is cool. I just let it run an accept the hit to to my phone’s battery. Jami is fairly easy to use and looks friendly too, which is helpful for getting non-technical friends to join you on it.
I struggled with Nextcloud Talk too.
Highly recommend Jami 👍
Just so you know you can get push notifications on Jami. Jami has been supporting unified push notification for a while now, but it’s opt-in, some might not opt for it considering reducing privacy a bit, as some actually disable the proxy and some phone specific feature intending to prevent battery exhausting too fast.
For unified push support you can take a look at jami’s article about its unified push support. I use ntfy
