VoWiFi Dual Call feature description
The VoWiFi Dual Call feature provides an incoming call indication to the user on SUB2,
when an ongoing call is active on SUB1.
Currently, on multi-SIM devices withVoWiFi+VoWiFi or VoLTE+VoWiFi configuration,
the IMS modem rejects the incoming or mobile-terminated (MT) call on SUB2
when an ongoing call is active on SUB1.
