Abstract

A method and system of an embodiment of the present invention may include receiving a call request directed to a called party, identifying announcement information associated with the call request, inserting the announcement information into a field of the call request and forwarding the call request.

Claims

1. A method, comprising:

providing a web based interface to receive an announcement customization, comprising an audio label, from a called party for a number;

receiving a call request directed to the called party;

identifying, using at least one computer processor, announcement information comprising the announcement customization associated with the call request;

determining that the call request is associated with a number having the announcement customization;

customizing the announcement information based at least in part on the announcement customization;

identifying an identifier referencing a notification alert pattern, wherein the identifier is a URL referencing the notification alert pattern;

adding the identifier to the announcement information;

inserting the announcement information into a field of the call request wherein the field is an alert info field in a header of a SIP INVITE message; and

forwarding the call request.

2. The method of claim 1 wherein the call request is received at a server associated with the called party.

3. The method of claim 1, further comprising:

determining that the called party has a call waiting service enabled.

4. The method of claim 1 wherein the announcement information further comprises one or more attributes associated with a calling party.

5. The method of claim 4 wherein the one or more attributes of the calling party comprise one or more of:

a caller number, a caller name and a caller location.

6. The method of claim 1 further comprising:

identifying an address referencing a resource for synthesizing audio for the audio label; and

adding the address to the announcement information.

7. The method of claim 6 wherein the address is a URL referencing a server with text to speech synthesis functionality.

8. The method of claim 1, wherein identifying the announcement information includes generating announcement text based on one or more attributes of the calling party and including the announcement text in the announcement information.

9. The method of claim 8 wherein the audio retrieved is an alerting pattern identified by a URL in the call request.

10. The method of claim 8 further comprising:

determining a user interface device state; and

sending notification information corresponding to the device state.

11. The method of claim 1, wherein identifying the announcement information includes selecting a notification alert pattern based on one or more attributes of the calling party, and including an indicator of the notification alert pattern in the announcement information.

12. A non-transitory computer readable media comprising:

code to perform the acts of the method of claim 1.

13. A method comprising:

transmitting via a web based interface announcement customizations for one or more numbers;

receiving a call request from a packet-switched network;

identifying, using at least one computer processor, announcement information associated with the call request wherein identifying the announcement information comprises identifying information located in an alert info field of the call request and wherein further the announcement information includes a URL;

determining that the call request is associated with a number having a customized announcement comprising an audio label specified by and recorded by a called party;

customizing the announcement information based at least in part on the customized announcement;

identifying an identifier referencing a notification alert pattern, wherein the identifier is a URL referencing the notification alert pattern;

adding the identifier to the announcement information;

retrieving audio associated with the announcement information from a network element communicatively coupled to the packet-switched network; and

providing the audio to a user interface.

14. The method of claim 13 wherein the URL references a server with text to speech synthesis functionality.

15. The method of claim 13 wherein retrieving the audio comprises sending an HTTP request to a server with text to speech functionality, the HTTP request including announcement text, and receiving a synthesized audio file generated from the announcement text contained in the HTTP request.

16. A non-transitory computer readable media comprising:

code to perform the acts of the method of claim 13.

17. A system comprising:

a web based interface to receive announcement customizations for one or more numbers;

a server communicatively coupled to an IP network to;

receive a SIP INVITE directed to a called party from the IP network,

determine that the called party has a call waiting service enabled,

identify announcement information based on calling party information in the SIP INVITE,

customize the announcement information in the event the SIP INVITE is associated with a number having a customized announcement, wherein the customization is based at least in part on a customization specified by the called party for a number associated with a calling party and comprises at least in part an audio label;

identify an identifier referencing a notification alert pattern, wherein the identifier is a URL referencing the notification alert pattern;

add the identifier to the announcement information;

insert the announcement information comprising announcement text corresponding to the audio label into the SIP INVITE into an alert info field,

transmit the SIP INVITE; and

a SIP device associated with the called party and coupled to the server, the SIP device including a SIP user agent, to;

receive the SIP INVITE from the server,

identify the announcement information in the SIP INVITE,

retrieve audio information from a network element communicatively connected to the IP network based on the announcement information, and

provide the audio information to a user interface connected to the SIP device, wherein the audio information is a conversion of the announcement text to speech.

18. The system of claim 17 wherein the audio information comprises one or more audio files.
