a second DTMF or voice signal corresponds to a decrease in volume of playback of the ringback tone;

a third DTMF or voice signal corresponds to a pause in playback of the ringback tone;

a fourth DTMF or voice signal corresponds to a change in ringback tone.

9. The method of claim 1 , wherein the step of changing the playback characteristic of the ringback tone comprises the step of:

changing the playback characteristic of the ringback tone only during the call setup for the call to the called communication device.

10. A method, comprising the steps of:

receiving an initial address message, for a call from the calling communication device to a called communication device, from a switching center associated with the called communication device, wherein the call is routed by a service control point to an intelligent peripheral that receives the initial address message;

sending an address complete message to the switching center to create the communication path to the calling communication device;

performing a playback of a ringback tone to the calling communication device by the intelligent peripheral through employment of a communication path to the calling communication device during a call setup for the call; and

monitoring the communication path during the call setup for the call and during the playback of the ringback tone by the intelligent peripheral for input from a user of the calling communication device that corresponds to a selected change to a characteristic of the playback of the ringback tone to the calling communication device;

receiving input during the call setup for the call and during the playback of the ringback tone from the user of the calling communication device through employment of the communication path; and

changing the characteristic of the playback of the ringback tone during the call setup for the call and during the playback of the ringback tone based on the input from the user of the calling communication device.

11. The method of claim 10 , wherein the step of changing the characteristic of the playback of the ringback tone based on the input from the user of the calling communication device comprises the step of:

changing the characteristic of the playback of the ringback tone during the playback of the ringback tone.

12. The method of claim 10 , wherein the step of changing the characteristic of the playback of the ringback tone based on the input from the user of the calling communication device comprises the step of:

changing a volume of the playback of the ringback tone.

13. The method of claim 10 , wherein the step of changing the characteristic of the playback of the ringback tone based on the input from the user of the calling communication device comprises the step of:

performing a pause, stop, rewind, fast-forward, or shuffle of the ringback tone.

14. The method of claim 10 , further comprising the step of:

sending a message to the calling communication device to indicate to the user one or more associations between a pre-determined change to a characteristic of the playback and a pre-determined input.

15. The method of claim 10 , wherein the step of monitoring the communication path for the input from the user of the calling communication device comprises the step of:

monitoring the communication path for input that corresponds to a selected change to a characteristic of the playback of the ringback tone;

wherein the step of changing the characteristic of the playback of the ringback tone based on the input from the user of the calling communication device comprises the step of:

performing the selected change to the characteristic of the playback of the ringback tone.

16. The method of claim 10 , wherein the step of monitoring the communication path for the input from the user of the calling communication device comprises the step of:

monitoring the communication path for one or more DTMF or voice signals from the calling communication device.

17. The method of claim 10 , wherein the step of performing the playback of the ringback tone to the calling communication device through employment of the communication path to the calling communication device comprises the step of:

performing a playback of the ringback tone to the calling communication device during the call setup for a call placed from the calling communication device;

wherein the step of monitoring the communication path for input from the user of the calling communication device comprises the step of:

monitoring the communication path for input from the user of the calling communication device during the call setup for the call placed from the calling communication device.

18. A method, comprising the steps of:

performing a playback of a ringback tone, by an intelligent peripheral, to a calling communication device during a call setup for a call placed from the calling communication device;

monitoring a communication path to the calling communication device during the call setup for the call and during the playback of the ringback tone, by the intelligent peripheral, for input from a user of the calling communication device, wherein the input corresponds to a selected change to the playback of the ringback tone to the calling communication device through employment of the communication path;
