Note: If you do not enter the parameters with the proper case and spelling, the scripts will fail.
Note: In Cisco Unified CME 4.2 and later versions, music on hold (MOH) must be configured for services using MOH. If an MOH server is not available, incoming calls disconnect. For configuration information, see "Configuring Music on Hold" in the Cisco Unified CME System Administrator Guide.
For example (simple MoH multicast configuration):
multicast moh 126.96.36.199 port 2000

Sample B-ACD Configuration
The following example sets up a single AA service, called aa, and a call-queue service, called queue, using the Tcl scripts in flash memory. The service command specifies the location of the scripts. The call flow for this example is as follows:
- Callers dial an AA pilot number, 800 555-0123, to reach this AA service. They are greeted with the prompt that is stored in the audio file called en_bacd_welcome.au. The en prefix of the filename matches the language code in the paramspace language command. The identifier portion of the filename, _bacd_welcome.au, matches the name specified in the param welcome-prompt command.
- Note: The filename within flash will be "en_bacd_welcome.au" - if you specify the "en" prefix within the "welcome-prompt" param, you will experience about 20 seconds of silence after the call is answered and before the AA service continues to the menu portion of the script. This is the result of the script not being able to find the welcome greeting sound file. The prefix will vary depending on the language found within the welcome greeting, specified ultimately by the "paramspace english language en" (or similar) command.
- After the welcome prompt is played, the menu options audio file, en_bacd_options_menu.au, tells callers that they have the following options: "Press 1 if you know your party's extension; press 2 for sales; press 3 for service."
- A caller who dials 2 is connected to the hunt-group pilot number 1111. If all the phones in that hunt group are busy, the call is put into a queue for that hunt group. Up to 15 calls can be held in each queue. While the call is in the queue, it tries again every 15 seconds to reach a phone in the hunt group. The second-greeting message is played to the caller every 60 seconds while the call is in the queue. If the call is unable to connect to a phone in the hunt group after 700 seconds, the retry timer expires. The call is considered unanswerable and it is deleted from the queue.
- After the call leaves the call queue, it is sent to extension 5003, the alternate destination that is specified in the param voice-mail command. If this number is busy, the call tries twice more to connect with it. If the call is still unable to connect after the retries, the call disconnect prompt (en_bacd_disconnect.au) is played and the call is disconnected.
