Apparatus and methods for origination of voice and messaging communication in a network

摘要

A method that incorporates teachings of the subject disclosure may include, for example, receiving a query from a call session server for a first pointer associated with a telephone number of a terminating device of a requested communication session, transmitting to the call session server the first pointer including a session initiation protocol uniform resource identifier associated with the terminating device to initiate an internet protocol communication session, receiving a notification from the call session server responsive to the call session server failing to initiate the internet protocol communication session, and transmitting to the call session server a second pointer including a telephone protocol uniform resource identifier for originating a circuit-switched communication session responsive to receiving the notification. Other embodiments are disclosed.

主权项

1. A device, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving from a telephone number mapping server a first pointer comprising a session initiation protocol uniform resource identifier associated with a terminating device and a second pointer comprising a telephone protocol uniform resource identifier associated with the terminating device;transmitting a request to a subscriber server for an identity of a terminating call session control function server associated with the terminating device;receiving from the subscriber server one of an identity of the terminating call session control function server or a notification of an unsuccessful identification of the terminating call session control function server;transmitting the session initiation protocol uniform resource identifier of the first pointer to the terminating call session control function server for initiating a packet-switched communication session with the terminating device responsive to receiving the identity; andtransmitting the telephone protocol uniform resource identifier of the second pointer to a gateway server for initiating a circuit-switched communication session with the terminating device responsive to receiving the notification.
