Abstract
A user equipment (“UE”) connected to a first network that performs methods including receiving a page from the first network indicating an incoming voice call, when it is determined the voice call was not successfully connected, incrementing a value of a counter and when the value satisfies the threshold, switching from the first network to a second network. Another method includes originating a voice call via the first network, when it is determined the voice call was not successfully connected, opening a socket connection with the first network and attempting to re-originate the voice call via the first network. Another method includes determining whether the UE has switched a connection from a first network to a second network and when it is determined that the UE has switched the connection to the second network, initiating an action by the UE.
