Session control logic with internet protocol (IP)-based routing

A computer-implemented method comprising:

• receiving, at a server, from a user equipment (UE), over a telecommunications network, a session request to establish a communication session, the session request including a destination Internet Protocol (IP) address, wherein the destination IP address is derived based at least in part on a mobile station international subscriber directory number (MSISDN) and includes a virtual IP (VIP) address;
• identifying a network service based at least in part on the destination IP address;
• retrieving an IP address of an endpoint device from a registration entry associated with the network service;
• replacing the destination IP address in the session request with the IP address of the endpoint device to generate a modified session request;
• and
• routing, by the server and over the telecommunications network, the modified session request to the endpoint device based at least in part on the IP address of the endpoint device.

A system comprising at least a server including:

• one or more processors;
• and
• one or more memories storing computer-executable instructions that, when executed by the one or more processors, cause the server to:
• receive, from a user equipment (UE) over a telecommunications network, a Session Initiation Protocol (SIP) request to establish a communication session, the SIP request including a destination Internet Protocol (IP) address, wherein the destination IP address is derived based at least in part on a mobile station international subscriber directory number (MSISDN) and includes a virtual IP (VIP) address;
• identify a network service based at least in part on the destination IP address;
• retrieve a physical (PHY) IP address of an endpoint device from a registration entry associated with the network service;
• replace the destination IP address in the SIP request with the PHY IP address of the endpoint device to generate a modified SIP request;
• and
• route, over the telecommunications network, the modified SIP request to the endpoint device based at least in part on the PHY IP address of the endpoint device.
