Push notifications without DHT proxy

Can push notifications be used when the server is not a DHT proxy?
In the Android version, the DHT proxy and push notification options are basically separate (but the DHT proxy is automatically turned on when you turn on the push notification), while in the iOS version, the DHT proxy option is only displayed in the settings when the push notification is turned on.
If push notifications rely on DHT proxy information, then the settings for push notifications can be added to the OpenDHT protocol to allow applications to submit push notification credentials to the DHT proxy server. This will allow the custom push notification server to work, allowing notifications via other messaging software or even SMS.

Yes, SIP account also supports push notification.

F-droid build is the UnifiedPush variant, the UnifiedPush variant allows you to use your own push server. But using SMS (:rofl:I believe there is no SMS app which is a UnifiedPush distributor) is not a good idea, DHT proxy server uses push notifications to inform the client that it can retrieves new values, you may cost a lot…

The “push notifications” I’m talking about here don’t require the app to be launched, but rather alert the user to react in a timely manner, which can be useful if Jami can’t be installed on the user’s usual device or if the battery saving policy is too restrictive.
I would have liked to set up a bot that monitors DHT to tell me what’s going on, and this thing works in a similar way to push notifications.

Text messages in swarm are not on the DHT network, they’re sent via the connection (currently, is TLS over ICE TCP) between peers, you have to run a jami-daemon and implement push notifications on it.
