Recently, I  had a request from my friend asking for a help to divert the CME reception calls at 5pm to a pre-defined mobile number and UN-divert the call at 8:30am when the receptionist started working. I was going to post it last month but due to being busy in project work and other commitments I couldn’t possible get even a minute to post this !!

Anyhow, It took me about 30 minutes to think about the best solution and here is what I came up with and it works perfectly.

If you have any better way to achieve this please let me know.

required: CME router version 4 or 7x (didn’t test on older), any model of cisco router.

Here are the steps:

Steps #1
———————————————————————————
Copy below call-divert.tcl and call-un-divert.tcl in a notepad and save them as .tcl extension

Now you’d be thinking what the hell ephone-dn is doing here.  Actually ephone-dn 50 is a receiption octoline here is the sample config of DN.

ephone-dn  50  octo-line
number 2000 secondary 94232000
pickup-group 88
label Nice-Dolls – 3002
description 02 23233002
name Reception
call-forward busy 4222
call-forward noan 4222 timeout 50
corlist incoming INTL-COR
no huntstop
hold-alert 120 originator
transfer-mode consult

IN above ephone-dn, 94232000 is the main DID number which hits CME router and receptionist picks it up and then transfers to the phones.

Step #2:
———————————————————————————

Put the above 2 files in a TFTP server and then copy them into the flash:

HQ-CME#dir *.tcl
Directory of flash:/
95  -rw-         481  Jul 17 2009 14:40:20 +10:00  call-divert.tcl
96  -rw-         484  Jul 17 2009 14:40:30 +10:00  call-un-divert.tcl
512065536 bytes total (443867136 bytes free
HQ-CME#

Step #3:

Final step, Kron about two scripts to run them in a required time. BTW, cron used to be a unix/linux worlds keyword but it seems Cisco has  adapted it by using a fancy word like “Kron” duh!

The original requirement was 5pm calls divert to a mobile phone and 8:30 am call un-divert.

Here is how they should be cron’d:

First two cron policy lists and reference the two .tcl scripts into them:

kron policy-list call-divert
cli tclsh call-divert.tcl  ! for call divert

!
kron policy-list call-un-divert
cli tclsh call-un-divert.tcl ! for call un-divert

Then create 2 kron occurance and put above policy list with required divert / undivert time in them.

kron occurrence call-divert at 14:59 recurring !
policy-list call-divert Divert receiption call at 4:59pm

!
kron occurrence call-un-divert at 8:29 recurring
policy-list call-un-divert ! Undivert receiption call at 8:29AM
!
If anyone has better solution, please feel free to provide your feedback.

I keep getting a lot of request regarding what type of gear I used for my CCIE voice lab, and finally decided to put this up in my blog:
Note: with below list of gears I was able to do 95% of lab tasks. For Cat6k , no need to buy it. There are hardly 10-12 commands which you’ll need to play with, that can be done using a online rented racks.
Also, there is no need to buy expensive VG248. You can practice it on Cisco partner website or online rack. I believe if you are very bad student you should be fine in 2 hour with VG248 and CAT6k.

HQ:
——————————
1 x 3560- 8 port switch
1 x 2801 with 1 x vwic2-1T1 or E1T1 + 1 x WIC-2T + 1 x PVDM2-16 + 1 x VWIC-2FXS
2 x serial cables
1 x RJ45 E1 cross over cable (remember this is not ethernet cross over, pins are TX-1,2 & RX- 4,5)
3 or 2 x IP phone 7960G

SiteB:
——————————

1 x 2811 with 1 x VWIC2-1T1+  1 x WIC-1T + 1x PVDM2-16 + 1 x NM-16ESW
1 x serial cross cable
2 x 7960G IP phone
1 x ATA186
2 x IP phones 7960G (buy external 48 volt power pack coz NM16esw doesn’t have inline power and buying 2 48 volt external power pack costs fraction than nm-16esw-PWR)

SiteC:
——————————

1 x 3560-8 port switch
1 x 2801 router with 1 x AIM-CUE +   1 x PVDM2-16 +   1 x VWIC2-1E1 +   1 xVWIC-1T
1 x Serial crossover cable
1 x RJ45 E1T1 crossover
2 x 7960G IP phone

PSTN Switch + Frame-Relay router:
————————————————–

The trick here is to save number of hardware required for the lab. I was able to do both function using just 1 router without secrifying anything.

1 x 2811 with 1 x VWIC-2T1  or VWIC2-2T1 + 1 x vwic-1E1 or VWIC2-1E1 + 2 x VWIC2T + 1 x PVDM2-16
1 x 7960G IP phone (PSTN phone, buy external power pack as this phone will be hooking on fas0/0 which has no inline power)
1 x rj45 cable (connecting phone to the pstn router)
I used to only allocate 1-3 timeslots for E1T1 for  each location. In that way you have plenty of PVDM. workbooks uses 1-6 or 1-15 timelsots at each location.

Note: When ordering  serial cable pay special attention to DTE/DCE.

Call managers, Unity, IPCC hardware/ VMWARE server:
——————————————————————————–

Any server with 4 gig RAM + at least DUAL XEON 3 Gig will do the job. I had this config of hardware and was able to run CCM publisher, subscriber and unity at the same time without performance degradation.
