Abstract

A method for use of voice call restriction data to restrict mailbox-to-mailbox message transfers. When a subscriber logs into his or her voice mail box and seeks to send a voice mail message to another subscriber'"'"'s voice mail box, reference will be made to voice call restriction data that indicates whether voice calls are allowed between the subscriber and the other subscriber. If the voice call restriction data indicates that voice calls are allowed between the subscribers, then the voice mail system will allow the requested mailbox-to-mailbox message transfer. On the other hand, if the voice call restriction data indicates that voice calls are not allowed between the subscribers, then the voice mail system will not allow the mailbox-to-mailbox message transfer.

Claims

1. A method comprising

(a) in a voice mail system, connecting a first subscriber to a first voice mail box associated with the first subscriber;

(b) through the first voice mail box, receiving into the voice mail system from the first subscriber a request for the voice mail system to send a voice mail message to a second voice mail box associated with a second subscriber; and

(c) responsive to the request, (i) determining whether voice call restriction data indicates that voice calls between the first subscriber and the second subscriber are allowed by sending a Check Restriction Header Parameter to a SCP (Service Control Point), (ii) granting the first subscriber'"'"'s request to send the voice mail message to the second voice mail box associated with the second subscriber if the voice call restriction data indicates that voice calls are allowed and if the second mailbox exists, and (iii) denying the first subscriber'"'"'s request to send the voice mail message to the second voice mail box associated with the second subscriber if the voice call restriction data indicates that voice calls between the first subscriber and the second subscriber are not allowed.

2. The method of claim 1, wherein the voice call restriction data resides at a service control point (SCP), and wherein determining whether the voice call restriction data indicates that voice calls between the first subscriber and the second subscriber are allowed comprises:

providing a query from the voice mail system to the SCP;

the SCP responsively referencing the voice call restriction data to determine whether the voice call restriction data indicates that voice calls between the first subscriber and the second subscriber are allowed; and

providing a response from the SCP to the voice mail system.

3. The method of claim 2, wherein providing the query comprises providing the query in a Session Initiation Protocol (SIP) message via a packet-switched network connection.

4. The method of claim 3, wherein the SIP message contains a check-restriction parameter, the SCP detecting the check-restriction parameter and responsively carrying out the referencing function in response to the query.

5. The method of claim 1,

wherein the voice mail system comprises a first voice mail platform serving the first voice mail box and a second voice mail platform serving the second voice mail box, and

wherein granting the first subscriber'"'"'s request to send the voice mail message to the second voice mail box associated with the second subscriber comprises sending the voice mail message over a network connection from the first voice mail platform to the second voice mail platform, for storage of the voice mail message in the second voice mail box.

6. The method of claim 5, further comprising:

before sending the voice mail message from the first voice mail platform to the second voice mail platform, the first voice mail platform communicating with the second voice mail platform to validate the second voice mail box.

7. The method of claim 6, wherein communicating with the second voice mail platform to validate the second voice mail box comprises communicating with the second voice mail platform to determine whether the second voice mail box exists.

8. The method of claim 1, wherein connecting the first subscriber with the first voice mail box associated with the first subscriber comprises:

receiving a call from the first subscriber to the voice mail system, and connecting the first subscriber with an interactive voice response system through which the first subscriber is able to manage the first voice mail box.

9. The method of claim 1, wherein connecting the first subscriber with the first voice mail box associated with the first subscriber comprises:

receiving via a web interface a request from the first subscriber to connect with the first subscriber'"'"'s voice mail box, and connecting the first subscriber with a web-based interface with the first voice mail box.

10. The method of claim 1, wherein:

the request for the voice mail system to send the voice mail message to the second voice mail box associated with the second subscriber comprises a compose-and-send request.

11. The method of claim 10, wherein granting the first subscriber'"'"'s request to send the voice mail message to the second voice mail box associated with the second subscriber comprises, in order:

prompting the first subscriber to enter the voice mail message;

receiving the voice mail message from the first subscriber; and

providing the received voice mail message to the second voice mail box.

12. The method of claim 1, wherein:

the request for the voice mail system to send the voice mail message to the second voice mail box associated with the second subscriber comprises a message-forward request.

13. The method of claim 1, wherein:

the request for the voice mail system to send the voice mail message to the second voice mail box associated with the second subscriber comprises a send-reply request.

14. The method of claim 1, wherein granting the request comprises:

storing in association with the second voice mail box a pointer to the voice mail message, to facilitate subsequent retrieval of the voice mail message by the second subscriber.

15. The method of claim 1, further comprising:

maintaining in data storage at the voice mail system profile data indicating for each of a plurality of subscribers whether the subscriber subscribes to a message transfer restriction service; and

carrying out step (c) only if the profile data indicates that at least one of the first subscriber and the second subscriber subscribes to the message transfer restriction service.

16. The method of claim 1, further comprising:

at another time, using the voice call restriction data to determine whether to allow a voice call to be placed from the first subscriber to the second subscriber.

17. The method of claim 16, wherein using the voice call restriction data to determine whether to allow a voice call to be placed from the first subscriber to the second subscriber comprises:

a switch receiving a request to place the voice call;

the switch querying to a service control point (SCP) that maintains the voice call restriction data; and

the SCP referencing the voice call restriction data to determine whether to allow the voice call, and the SCP instructing the switch accordingly.

18. A method comprising:

maintaining, for a first voice mail platform, profile data indicating respectively for each of a plurality of subscribers whether the subscriber subscribes to a mailbox transfer restriction service;

receiving into the first voice mail platform from a first subscriber a request to send a voice message to a second subscriber'"'"'s voice mail box served by a second voice mail platform;

responsive to the request, the first voice mail platform referencing the profile data to determine whether at least one of the first subscriber and the second subscriber subscribes to the mailbox transfer restriction service;

in response to a determination that the first subscriber subscribes to the mailbox transfer restriction service, the first voice mail server sending a first Session Initiation Protocol (SIP) message over a packet-switched network to a Service Control Point (SCP) that manages call restriction data and including in the first SIP message a Check Restriction header parameter;

the SCP receiving the first SIP message, detecting the Check Restriction header parameter and, responsive to detecting the Check Restriction header parameter, checking the call restriction data to make a determination of whether to allow the requested sending of the voice message to the second subscriber'"'"'s voice mail box, wherein the determination is to allow the requested sending of the voice message to the second subscriber'"'"'s mailbox only when the call restriction data indicates that voice calls between the first and second subscriber are allowed; and

if the determination is to allow the requested sending of the voice message to the second subscriber'"'"'s voice mail box, then (i) the SCP sending to the first voice mail platform a second SIP message indicating that the sending is allowed, (ii) the first voice mail platform receiving the second SIP message and responsively communicating with the second voice mail platform to determine whether the second subscriber'"'"'s voice mail box exists, and (iii) in response to a determination that the second subscriber'"'"'s voice mail box exists, prompting the first subscriber to speak the voice message, receiving and recording the voice message, and sending the recorded voice message to the second voice mail platform for storage in the second subscriber'"'"'s voice mail box.

19. The method of claim 18, further comprising:

if the determination is to not allow the requested sending of the voice message to the second subscriber'"'"'s voice mail box, then (i) the SCP sending to the first voice mail platform a third SIP message indicating that the sending is not allowed, and (ii) the first voice mail platform receiving the third SIP message and responsively providing an announcement to the first subscriber denying the request.
