Ensure that Communication Manager has a collection resource to accept the touch-tone digits entered by a caller. The resource used for collecting and interpreting touch-tone digits is a unit of hardware called a Touch-Tone Receiver (TTR). The TTRs are provided on the call classifier and tone detector circuit packs, one of which is required for Call Prompting.

The number of TTRs that are required is configured according to the following sources:

• Customer input to the Avaya Account Team.

• Account team input to the configurator tool.

For existing systems that are adding a Call Prompting application, the appropriate number of TTRs can be based on two the following factors:

• Account team input to the configurator tool.

• Application review by the Avaya Design Center.

The process of collecting CINFO digits does not require TTRs.

Outside callers must have a touch-tone telephone to enter the digits that are requested by the collect digits command. For callers who are using rotary dialing, the Call Prompting time out takes effect, the collect digits command times out, and vector processing continues at the next step. As a precaution, always provide a default treatment such as a route-to attendant command, or a queue-to split command, in the vector script unless the script is created exclusively for users of touch-tone telephones.
