Description
Nextcloud talk is a self hosting messaging service. In versions prior to 12.3.0 the Nextcloud Android Talk application did not properly detect the lockscreen state when a call was incoming.

It is recommended that the Nextcloud Android Talk App is upgraded to 12.3.0. There are no known workarounds.
