[Story] Regression on: Stopping ongoing (CallKit) ringing if the other devices takes the call

[fkwp]

Description

We have a regression on stopping ongoing call ringing if the other devices meanwhile takes the call:

• Using Element X 1.9.3 (134) on iPad
• If the app is in foreground ringing stops
• During Lockscreen or if the app is in background ringing/CallKit does NOT stop

(same was reported for Element X on Android)

Acceptance criteria

• Call ringing stops of the call is meanwhile picked up by another device of that user

https://github.com/element-hq/element-x-ios/pull/3442 included https://github.com/matrix-org/matrix-rust-sdk/blob/bb55493a47fafb5f45c0e337cb076252d101702a/crates/matrix-sdk-ui/src/room_list_service/mod.rs#L90 which was the necessary fix to get m.call.member state synced into the App.

Now I am wondering if we need something similar for the push notification workers.

Tested on Android 0.7.4 nightly (40007040, 11:12AM) which still keeps ringing if:

• the caller hangs up the call
• the call is taken by another device of the callee
