Solutions are disclosed that provide for internet protocol (IP) multimedia subsystem (IMS) session continuity with stored authentication. When a user equipment (UE) registers with a first proxy call session control function (P-CSCF), the first P-CSCF stores authentication information for the UE, and binding information for an IMS session in an authentication database, for example in a storage area network (SAN). Upon an outage of the first P-CSCF, a second P-CSCF (in the same pool) retrieves the authentication information and binding information in lieu of requiring the UE to register. The second P-CSCF is then able to act as a proxy for the IMS session. This is available for mobile originating (MO) and mobile terminating (MT) calls. For MO calls, the call setup is sped up. For MT calls, the UE is able to receive the call, rather than the call being missed.
