System and method for conveying end-to-end call status
First Claim
1. A non-transitory machine-readable storage medium, comprising executable instructions which, responsive to being executed by a processor, cause the processor to facilitate performance of operations comprising:
- receiving from a unified messaging system a session initiation protocol subscribe message over a primary call leg requesting outdial event notification on a secondary call leg responsive to the unified messaging system placing a call outside of its local access and transport area, wherein the unified messaging system operates in an internet protocol multimedia subsystem network, and wherein the primary and the secondary call legs bypass the internet protocol multimedia subsystem network;
placing a call on the secondary call leg responsive to receiving, on the primary call leg, outdial information from the unified messaging system, wherein receiving the outdial information is responsive to an autodial request to a voicemail message of the unified messaging system, and wherein the outdial information is directed towards a calling party of the voicemail message; and
submitting a session initiation protocol notify message to the unified messaging system that indicates outdial events associated with call status of the call on the secondary call leg; and
responsive to the call on the secondary leg being unanswered;
receiving alternative outdial information directed to the calling party of the voicemail message; and
placing another call on the secondary leg responsive to receiving the alternative outdial information, wherein the placing of the other call does not require receiving from a unified messaging system another session initiation protocol subscribe message over the primary call leg requesting outdial event notification on the secondary call leg,wherein a calling card server performs session initiation protocol messaging associated with one of the session initiation protocol notify message or the session initiation protocol subscribe message, andwherein the call is placed on a voice over internet protocol network that produces the outdial events.

Abstract
A system that incorporates teachings of the present disclosure may include, for example, receiving a session initiation protocol (SIP) subscribe message over a primary call leg requesting outdial event notification on a secondary call leg. Receiving of the call is responsive to a unified messaging system placing a call outside of its local access and transport area. A call is placed on the secondary call leg responsive to receiving outdial information on the primary call leg. Alternative outdial information directed to the calling party is received responsive to the call on the secondary leg being unanswered. Another call is placed on the secondary leg responsive to receiving the alternative outdial information without requiring receipt of another SIP subscribe message over the primary call leg. A calling card server performs SIP messaging associated with one of the SIP notify message or the SIP subscribe message. Other embodiments are disclosed.

7. A unified messaging system, comprising:
-
a memory that stores executable instructions; and a processor coupled to the memory, wherein the processor, responsive to executing the instructions, facilitates performance of operations comprising; submitting to a calling card server over a primary call leg a session initiation protocol subscribe message requesting outdial event notification for a call on a secondary call leg responsive to an autodial request to a caller identification associated with a calling party of a voicemail message of the unified messaging system, and wherein the call on the secondary call leg is directed to said caller identification, wherein the unified messaging system operates in an internet protocol multimedia subsystem network, and wherein the primary and the secondary call legs bypass the internet protocol multimedia subsystem network; receiving over the primary call leg a session initiation protocol notify message from the calling card server indicating outdial events associated with placing the call over the secondary call leg; responsive to the call on the secondary leg directed to said caller identification being unanswered; determining an alternative destination number of the calling party of the voicemail message; and initiating another call on the secondary leg responsive to alternative destination number, wherein the initiating of the other call does not require receiving from a unified messaging system another session initiation protocol subscribe message over the primary call leg requesting outdial event notification on the secondary leg; submitting a session initiation protocol invite message to establish communications with the calling card server over the primary call leg, wherein the session initiation protocol invite message comprises outdial information to place the call over the secondary call leg; and receiving session initiation protocol notify messages from the calling card server regarding call status associated with the call when placed over the secondary call leg. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A calling card system, comprising:
-
a memory that stores executable instructions; and a processor coupled to the memory, wherein the processor, responsive to executing the instructions, facilitates performance of operations comprising; transmitting a session initiation protocol notify message to a unified messaging system over a primary call leg, wherein the session initiation protocol notify message includes call status associated with a secondary call leg, wherein the unified messaging system operates in an internet protocol multimedia subsystem network, and wherein the primary and the secondary call legs bypass the internet protocol multimedia subsystem network; initiating a call on the secondary call leg responsive to an autodial request to a caller identification of a calling party of a voicemail message received from the unified messaging system in response to the voicemail message presented by the unified messaging system, wherein the caller identification of the calling party is obtained from outdial information associated with the voicemail message; responsive to the call on the secondary leg being unanswered; determining another autodial request to an alternative destination number of the calling party of the voicemail message; and initiating another call on the secondary leg responsive to the alternative destination number, wherein the initiating of the other call does not require receiving from a unified messaging system another session initiation protocol subscribe message over the primary call leg requesting outdial event notification on the secondary leg; receiving, from the unified messaging system, the outdial information associated with the voicemail message; and receiving a session initiation protocol subscribe message requesting the call status on the secondary call leg. - View Dependent Claims (16, 17, 18, 19, 20)
