Call processing in a voicemail system
View Patent ↗A system that incorporates teachings of the present disclosure may include, for example, a method that involves receiving an indication that communications with a subscriber have been interrupted while engaged in voicemail processing, and recording a pointer to a last state of voicemail processing. Additional embodiments are disclosed.
1. A non-transitory computer readable medium storing computer program instructions, which, when executed on a processor, cause the processor to perform operations comprising:
detecting that a presentation of a voicemail message to a subscriber has been interrupted, resulting in an interruption;
responsive to the detecting, recording departure data comprising a departure mark that corresponds to the interruption;
receiving a selection of an option to resume presentation of voicemail processing from the departure mark;
adjusting the departure mark based on a duration of the interruption to an intermediate location that is after a beginning of a voicemail message and before a point that corresponds to the interruption, wherein an amount by which the departure mark is moved toward the beginning of the voicemail message is in direct relation to a length of the interruption;
resuming presentation of the voicemail message according to the departure data based on the selection of the option;
detecting that communications with the subscriber have been changed from an on-hold state to an off hold state;
responsive to the detecting that communications with the subscriber have changed, resuming presentation of the voicemail message according to the departure data;
detecting that the communications with the subscriber are on hold by receiving from a communication system a first session initiation protocol Re-INVITE message; and
detecting that the communications are off hold by receiving from the communication system a second session initiation protocol Re-INVITE message.
2. The non-transitory computer-readable medium of claim 1 , the operations further comprising:
pausing presentation of the voicemail message according to the departure mark.
3. The non-transitory computer-readable medium of claim 2 , the operations further comprising:
enabling a timer;
detecting an expiration of the timer during the interruption; and
terminating communications with the subscriber.
4. The non-transitory computer-readable medium of claim 1 , the operations further comprising:
detecting the interruption according to one among:
receiving a message originating from a network element of a communication system establishing communications between the subscriber and a voicemail service; and
monitoring interruptions in a bearer channel established by the communication system.
5. The non-transitory computer-readable medium of claim 1 , wherein the departure data comprises a pointer to a last session of a voicemail service.
6. The non-transitory computer-readable medium of claim 5 , wherein the pointer comprises a calling number of the subscriber, a state of a call processing tree operating in the voicemail service, a message identifier identifying a voicemail message recorded by the voicemail service, and a departure time.
7. A method comprising:
detecting that a presentation of a voicemail message to a subscriber has been interrupted, resulting in an interruption;
responsive to the detecting, recording departure data comprising a departure mark that corresponds to the interruption;
receiving a selection of an option to resume presentation of voicemail processing from the departure mark;
adjusting the departure mark based on a duration of the interruption to an intermediate location that is after a beginning of a voicemail message and before a point that corresponds to the interruption, wherein an amount by which the departure mark is moved toward the beginning of the voicemail message is in direct relation to a length of the interruption;
resuming presentation of the voicemail message according to the departure data based on the selection of the option;
detecting that communications with the subscriber have been changed from an on-hold state to an off hold state;
responsive to the detecting that communications with the subscriber have changed, resuming presentation of the voicemail message according to the departure data;
detecting that the communications with the subscriber are on hold by receiving from a communication system a first session initiation protocol Re-INVITE message; and
detecting that the communications are off hold by receiving from the communication system a second session initiation protocol Re-INVITE message.
8. The method of claim 7 , further comprising:
pausing presentation of the voicemail message according to the departure mark.
9. The method of claim 8 , further comprising:
enabling a timer;
detecting an expiration of the timer during the interruption; and
terminating communications with the subscriber.
10. The method of claim 7 , further comprising:
detecting the interruption according to one among:
receiving a message originating from a network element of a communication system establishing communications between the subscriber and a voicemail service; and
monitoring interruptions in a bearer channel established by the communication system.
11. The method of claim 7 , wherein the departure data comprises a pointer to a last session of a voicemail service.
12. The method of claim 11 , wherein the pointer comprises a calling number of the subscriber, a state of a call processing tree operating in the voicemail service, a message identifier identifying a voicemail message recorded by the voicemail service, and a departure time.
