no incoming call in background for linked device
steps:
- create an account "account1" on iOS device "device1"
- link another device "device2" to "account1"
- close jami on "device1"
- place a call to "account1"
- call screen presented on "device2" and "account1"
- answer call from "device2"
- finish a call
- place another call to "account1"
- call screen present only on "device2"
It could be fixed after reseting connections by disable/enable account
