Network City: April 2010

Configuring B-ACD services was one of the task that we wanted to look deep into it and for that we read the following comprehensive guide which was a key to got it configured successfully.

Here are the steps which were followed;

-- Creating ephone-hunt groups --

ephone-hunt 15 longest-idle
pilot 2000
list 2001, 2002
timeout 10, 10
!
!
!
!
ephone-hunt 16 sequential
pilot 3000
list 3001
timeout 20

-- Configuring AA scripts --
I had to download the whole b-acd-2.1.2.2.tar file to my flash first which consist of the following two tcl scipts
app-b-acd-2.1.2.2.tcl
app-b-acd-aa-2.1.2.2.tcl

through config terminal some mandatory parameters being defined as follows

application
service queue flash:app-b-acd-2.1.2.2.tcl --- named the service name as queue
param number-of-hunt-grps 2 --- we are using 2 hunt groups as earlier defined
param aa-hunt1 2000
param aa-hunt2 3000
param queue-len 15
param queue-manager-debugs 1 --- used with debug command to trace the script

service aa flash:app-b-acd-aa-2.1.2.2.tcl --- named the service name as aa
paramspace english index 1
paramspace english language en
paramspace english location flash:
param service-name queue --- refrencing the service name queue defined earlier
param handoff-string aa
param aa-pilot 1000 --- using pilot number 1000 for which we will define
the dial-peer accordingly
param welcome-prompt _bacd_welcome.au
param number-of-hunt-grps 2
param dial-by-extension-option 3 --- defining the dial by extention option as 3 explicitly

param max-extension-length 4
param second-greeting-time 30
param call-retry-timer 15
param max-time-call-retry 100
param max-time-vm-retry 2
param voice-mail 1002

-- Creating a VOIP dial-peer --

When someone dials the number 1000 it would initiate this dial-peer and the aa service will get activated. the 20.0.0.1 is the loopback address defined for CME

dial-peer voice 1000 voip
service aa
destination-pattern 1000
session target ipv4:20.0.0.1
incoming called-number 1000
dtmf-relay h245-alphanumeric
codec g711ulaw
no vad

-- Now Some diagnostic commands --

CME#call application voice load aa --- loading aa service ( you will need to load this service if you have changed the pre=defined parameters or have added other parameters)

---After we placed a call from softphone to pilot 1000 and during the call we ran the following command with output as follows--

CME#sh call application sessions
