Call setup and management for internet clients is simplified by splitting negotiation of media characteristics for the call into separate negotiations with an originating device and a destination device. Based on an initiation of a call from an originating device (e.g., an originating internet client) to a destination device (e.g., a destination internet client), a first media stream may be negotiated and opened between the originating device and an access node in communication with an internet protocol multimedia system (“IMS”) or other communications network. A second media stream may be negotiated and opened between the access node and the destination device through the IMS, and this negotiation may be masked from the originating device. The access node may connect the call by connecting the first media stream and the second media stream.

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.
