Recently, I had a request for a B-ACD to play a menu on a voice gateway at 8:00 a.m. and a different menu after 4:30 p.m. At the time, I knew that Event Manager could do the schedule, and actually, it worked, but the menu(b-acd, not aa) session was struck and stayed with old one. Using “call application session stop id [id]” can stop it, but a question came up with how could I use “show call application sessions” to extract the session id?
R4331#show call application sessions
Session ID 5D
App: queue
Type: Service
Url: flash:/bacd/app-b-acd-3.0.0.4.tcl
Anyhow, it took me a while and here are the steps:
Step 1 - Create two folder for work hour and after hour audio files
R4331#dir flash:
Directory of bootflash:/
353409 drwx 4096 Jan 23 2017 09:40:49 +00:00 bacd
16065 drwx 4096 Jan 22 2017 23:11:47 +00:00 bacd-ah
Step 2 - upload b-acd scripts and audio files to each folder:
Work hour folder
R4331#cd bacd
R4331#dir
Directory of bootflash:/bacd/
353410 -rw- 33880 Jan 22 2017 21:34:07 +00:00 app-b-acd-3.0.0.4.tcl

353419 -rw- 50391 Jan 23 2017 09:40:49 +00:00 en_bacd_welcome.au
After hour folder
R4331#cd ../bacd-ah
R4331#dir
Directory of bootflash:/bacd-ah/

Step 3 - inbound dial-peer to divert to b-acd application:
dial-peer voice 225 voip
service aa ← it’s work-hour application temporary
destination-pattern 5037526652
session protocol sipv2
session target ipv4:10.1.1.190 ←CME IP address
incoming called-number 5037526652
dtmf-relay rtp-nte
codec g711ulaw
no vad
Step 4 - outbound dial-peer to CUCM for extensions:
dial-peer voice 221 voip
destination-pattern 503[06]49....
session protocol sipv2
session target ipv4:10.1.1.10 ←pub
dtmf-relay rtp-nte
codec g711ulaw
no vad
!
dial-peer voice 220 voip
preference 1
destination-pattern 503[06]49....
session protocol sipv2
session target ipv4:10.1.1.20 ← sub
dtmf-relay rtp-nte
codec g711ulaw
no vad
Step 5 - music on-hold must be setup on the CME:
telephony-service
max-ephones 5
max-dn 10
ip source-address 10.1.1.190 port 2000
max-conferences 8 gain -6
call-forward pattern .T
call-forward system redirecting-expanded
moh enable-g711 "flash:/bacd/en_bacd_music_on_hold.au"
transfer-system full-consult
create cnf-files version-stamp Jan 01 2002 00:00:00
Step 6 - work hour and after hour voice applications:
!
application
service aa-ah flash:/bacd-ah/app-b-acd-aa-3.0.0.4.tcl
paramspace english index 1
param dial-by-extension-option 5
param handoff-string aa-ah
param welcome-prompt _bacd_welcome.au
param operator 0
param call-retry-timer 15
paramspace english language en
param service-name queue-ah
param menu-timeout 6
param second-greeting-time 60
paramspace english location flash:/bacd-ah/
param max-time-vm-retry 2
param max-time-call-retry 5037526652
param voice-mail 5003
param aa-pilot
param max-extension-length 10
param number-of-hunt-grps 3
!
service aa flash:/bacd/app-b-acd-aa-3.0.0.4.tcl
paramspace english index 1
param number-of-hunt-grps 4
param menu-timeout 6
param dial-by-extension-option 5
param handoff-string aa
param operator 0
paramspace english language en
param max-time-vm-retry 2
param max-extension-length 10
param aa-pilot 5037526652

param second-greeting-time 60
param welcome-prompt _bacd_welcome.au
param call-retry-timer 15
param voice-mail 5003
param max-time-call-retry 700
param service-name queue
!
service queue flash:/bacd/app-b-acd-3.0.0.4.tcl
group-name queue
param name queue
param queue-len 15
param aa-hunt3 5036495533
param aa-hunt4 5030495505
param aa-hunt1 5036495503
param number-of-hunt-grps 4
param queue-manager-debugs 1
param aa-hunt2 5036495586
!
service queue-ah flash:/bacd-ah/app-b-acd-3.0.0.4.tcl
param aa-hunt1 5036495503
param number-of-hunt-grps 3
param queue-manager-debugs 1
param aa-hunt2 5036495586
param name ah
param queue-len 15
param aa-hunt3 5030495505
Step 7 - Tcl scripts to clean up stuck call application session and change service on the inbound dial-peer:
work-hour.tcl
set session [exec "show call application session"]
set id [string range $session 11 20]
if { $id == "" } { } else { exec "call application session stop id $id"}
ios_config "dial-peer voice 225 voip" "service aa"
ios_config "end"
ios_config "write memory" after-hour.tcl
set session [exec "show call application session"]
set id [string range $session 11 20]
if { $id == "" } { } else { exec "call application session stop id $id"}
ios_config "dial-peer voice 225 voip" "service aa-ah"
ios_config "end"
ios_config "write memory"Upload them to flash:
R4331#dir
Directory of bootflash:/
21 -rw- 230 Jan 24 2017 09:31:10 +00:00 work-hour.tcl
22 -rw- 233 Jan 24 2017 09:31:16 +00:00 after-hour.tcl
Step 8 - Event Manager scheduling with Tcl scripts:
event manager applet WEEKDAY_START
event timer cron name WEEKDAY_START cron-entry "1 8 * * 1-5"
action 1.0 cli command "enable"
action 1.1 cli command "tclsh flash:work-hour.tcl"
event manager applet WEEKDAY_END
event timer cron name WEEKDAY_END cron-entry "30 16 * * 1-5"
action 1.0 cli command "enable"
action 1.1 cli command "tclsh flash:after-hour.tcl"
event timer cron name WEEKDAY_START cron-entry "1 8 * * 1-5"
action 1.0 cli command "enable"
action 1.1 cli command "tclsh flash:work-hour.tcl"
event manager applet WEEKDAY_END
event timer cron name WEEKDAY_END cron-entry "30 16 * * 1-5"
action 1.0 cli command "enable"
action 1.1 cli command "tclsh flash:after-hour.tcl"
