Implementing the AA Tcl Script

Figure 15-3 shows the call flow that is associated with the AA script for CME.

Figure 15-3. CME AA Call Flow

The script takes the following actions when a call matches the incoming dial peer that is configured with the AA script:

• A caller places a call to the AA pilot number.
• The script plays Prompt en_welcome.au, thanking the caller. Then it plays Prompt en_enter_dest.au, asking the caller to enter an extension.
• If the caller enters no digits or presses 0, the script transfers the call to the operator extension that is configured in the command-line interface (CLI).
• If the caller enters an invalid destination, the script plays en_reenter_dest.au prompt, asking the caller to reenter the destination. The script repeats this up to three times. After the third time, the script plays en_disconnect.au prompt and disconnects the call.
• If the caller enters a valid extension, the script transfers the call.
• If the extension is busy, the script plays the en_dest_busy.au prompt, asking the caller to enter a different extension or try the call at a later time.
• If the extension is unreachable, the script plays the en_dest_unreachable.au prompt, asking the caller to enter a different extension or try the call at a later time.

Example 15-1 illustrates the configuration required to load the Tcl AA script for CME from the flash of the router.

Example 15-2 illustrates the configuration required to load the Tcl AA script for CME prior to Cisco IOS Release 12.3(14)T. The dial peer configuration is the same as in Example 15-1.
