Seems this method is not necessary after onAvalineCallerRemoved was implemented;

It does nothing because list item is always created with correct class type for Avaline caller.
For now Avaline Caller is removed from the LLSpeakerMgr List when it is removed from the Voice Client
session.
This happens in two cases: if Avaline Caller ends call itself or if Resident ends group call.

Probably Avaline caller should be removed from the LLSpeakerMgr list ONLY if it ends call itself.
