Cisco B-ACD on CME router - Drop-through option

In Cisco CME B-ACD, drop-through option can be configured so that when the AA services receive the incoming call, it will send the call directly to the call queue without provide menu options to callers.  This is useful for some small contact center backup, when the WAN link is downed and the site can't reach the contact center express or enterprise in the main site, it can still provide basic ACD service to the callers.

My Sample Configuration:

application

service aa flash:app-b-acd-aa-3.0.0.2.tcl

  paramspace english index 0

  param number-of-hunt-grps 1

  param drop-through-option 1

  param handoff-string aa

  paramspace english language en

  param max-time-vm-retry 2

  param aa-pilot 5000

  paramspace english location flash:

  param second-greeting-time 60

  param drop-through-prompt _dt_prompt.au

  param call-retry-timer 15

  param voice-mail 5555

  param max-time-call-retry 700

  param service-name callq

!

service callq flash:app-b-acd-3.0.0.2.tcl

  param queue-len 10

  param aa-hunt1 5600

  param queue-manager-debugs 1

  param number-of-hunt-grps 1

dial-peer voice 5000 pots

service aa

incoming called-number 5000

ephone-hunt 1 longest-idle

pilot 5600

list 5111, 5112

When there is incoming call, on both of the phone with ephone-dn 5111 and 5112, the message "1 call in queue" will be shown on the phone screen and you will know how many callers waiting in the call queue.
