Call not showing in Terminated State

[owl-madness]

I was trying to enable the calling feature using this package, in my office project. Using the sample project provided in this package, the incoming call is showing when the app is in foreground and sometimes when minimised. But in the TERMINATED STATE the calling is not showing !! also not showing sometimes when the app is minimised.

In my project I have tried with CXProvider and VoIP in ios native (swift), it is showing when call screen when VoIP is received. But it's only showing for a few seconds. That's why I tried with this package.

Is there anyone facing same issue?? Please help!!!!
