B-ACD queue length and voicemail issue


while configuring B-ACD on IOS 12.4.15T13 I ran into two issues:

with a voip dial-peer targeted to a loopback adress a single call will trigger the queue length (and therefore the display on the phones) to 2

and a TCL failure may occure when the call is forwarded to voicemail.

This is the config regarding B-ACD

  service QUEUE flash:/bacd/app-b-acd-
  param queue-len 3
  param aa-hunt1 798
  param number-of-hunt-grps 1
  param queue-manager-debugs 1
  service AA flash:/bacd/app-b-acd-aa-
  paramspace english index 0
  param number-of-hunt-grps 1
  param drop-through-option 1
  param handoff-string AA

  param max-time-vm-retry 2
  param aa-pilot 799

  param call-retry-timer 10
  param max-time-call-retry 300
  param voice-mail 699
  param service-name QUEUE

This is the debug to my failure output while forwarding to voicemail:

Can someone point me where I'm doing something wrong?

It seem's not be deterministic since sometimes a call may be directly transferred to voicemail and sometimes after timeout (my debug output)

Re: B-ACD queue length and voicemail issue


I've upgraded to IOS 15.0.1M2 and B-ACD and everything works as it should.

A single call triggers the menu to "1 call in queue" and forward to voicemail works as expected.

Not TCL Script failure so far.
