Abstract
In some implementations, a call session control function (CSCF) may identify information associated with a user equipment (UE). The CSCF may determine, based on the information, whether the UE is roaming in a circuit switched mobility network. The CSCF may transmit signaling associated with delivering a call to the UE, wherein the signaling bypasses a service continuity gateway (SCG) on a call delivery path when the UE is not roaming in the circuit switched mobility network and the signaling traverses the SCG on the call delivery path when the UE is roaming in the circuit switched mobility network.
