A device receives information associated with an outbound call from a calling party via a Public Switched Telephone Network (PSTN), and generates a request for the outbound call from the Public Switched Telephone Network (PSTN) using a remote procedure call (RPC) interface. The device also enables communication, via the remote procedure call (RPC) interface, of the outbound call with a Session Initiation Protocol (SIP)-based device associated with a called party. |
