Lesson learnd 2
This one is much more interesting.More like silly mistake turn into huge issue and CNS case open..well they dig into that for hours couldn't find the issue.Until I am the only Hero more like problem maker (:P decided to show up and fix that issue! Feel sorry for those people they had to spend long stressful night... We have an urgent requirement that when reception forward call to someone calling party should not hear ringing... Hmm
The reason behind is they want to take their time before answer those phones. maybe they are super busy all callers have to wait for a while. Well, none of my headache.. Now my question it how do I achieve that.. Think brain think.
In North America, the standard ring-back tone is a repeating 2-second tone with a 4-second pause between. The tone is 440 Hz + 480 Hz. (A little wise talk)
As far as I know some country does offer music instead of ring back tone
So how did we achieve that..stay tuned..
Lesson learned!! a
We ware implementing PLAR/Hotline whatever you would like to call for some very, very important person and department. We tested PLAR configuration on test phone and everything works fine. Now time to deploy on production environment.
Well, for the sip phone you need to have a sip dial on the phone. But nobody knew you have to define which line button you using PLAR and apply a SIP dial rule on that button.
So we deployed and all call made on those phone was going through the PLAR destination line.Untill know body knew sip dial rule have to defile which button you using for PLAR..... It was such a disaster :D
Lesson learned!!

Cut-over disaster!!
Well whos fault was that..Not mine lets point finger each other.


FYI! It was not really a disaster ..Eventually we endue migrate 270 phone successfully moving from Nortel to Cisco.The main reason we ware on panicking because there is no window for making any mistake.It's like if you do mistake or if you can't do it you will be hang or life sentence in prison.
Couple of issue we had to deal with.Only reason I am writing because I want to remember this horrible night my entire life.
* Initially 270 phone to deploy time window (7pm-11pm) .We end up finish all at 6AM morning :) Smile)
* Some of information was given to us was wrong.
* We did not had enough PoE on middle of our deployment.
*this one much better there was not enough VLAN or IP address to cover all those phone.(Note: To remmber it was not easy to add VLAN or IP. There was like two week protocol to follow to get those approved..lol)
*Those project manager we had not all of they know what they are doing.Not complaining I am sure managing all those stuff is hard .Just think maybe it would've been much better if there ware proper plan and coordination with networking or other team was on the place.
*Plus it was far from my house and I did not show up next day well my excuse is I was there until 6am plus 2hour to my house.There was like so many ticket was opend and so many phone was not registering and only one guy to deal with all those and he as kinda new to all those too.Okey okey I know I know all blame on me I am talking blame for that.I know I am getting old and becoming a little too lazy.plus I am getting fat bally now this days.
Not good !! Well lesson learned.
