Abstract

A method of operating a wireless calling device comprises connecting to a call tone provider configured to provide call tones, transferring a plurality of call tone requests to the call tone provider, receiving a plurality of call tones from the call tone provider in response to the plurality of call tone requests, transferring a call setup message to a telecommunication switch to initiate a call, receiving a call message from the telecommunication switch in response to the call setup message wherein the call setup message indicates a status of the call, processing the call message to select a one call tone from the plurality of call tones based on the status of the call, and audibly playing the one call tone.

Claims

1. A method of operating a wireless calling device, the method comprising:

connecting to a call tone provider configured to provide call tones;

transferring a plurality of call tone requests to the call tone provider;

receiving a plurality of call tones from the call tone provider in response to the plurality of call tone requests;

transferring a call setup message to a telecommunication switch to initiate a call;

receiving a call message from the telecommunication switch in response to the call setup message wherein the call message indicates a status of the call;

processing the call message to select a one call tone from the plurality of call tones based on the status of the call; and

audibly playing the one call tone.

2. The method of claim 1 wherein the wireless calling device comprises a wireless telephone.

3. The method of claim 1 wherein the wireless calling device comprises a computer.

4. The method of claim 1 wherein the call tone comprises a ringback tone.
