How to check firmware version for Cisco IP Phone 7940/7960

This process is a requirement before any firmware upgrade is done with a Cisco IP Phone. If you want to know more details on how to upgrade your firmware to SIP firmware, click here for my tutorial.

Boot up your phone. You can use either PoE or a power supply.  I used a power supply without plugging any internet connection. It will display “Ethernet disconnected.” You will just then wait for it to boot up. It might say “Configuring CM List“.

Press Settings -> Firmware Versions

Under Application Load ID, you will see your firmware version.


It looks like this. Mine is P0S3-8-12-00 means version SIP 8.12.

SCCP firmware: P003xxyyzzww: where x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.

SIP firmware: P0S3-xx-y-zz: where x represents the major version, y represents the minor version, and z represents the subversions.


There are other ways to check firmware on a Cisco IP Phone, you can check it out here.

Cisco IP Phone 7940 Easy Rear Stand Fix

I recently bought yet another Cisco IP Phone from 7940 from eBay. Usually, I don’t buy used electronics from eBay because I want to check and test any device before I buy it. I know once you commit buying on eBay you can’t back out like any other online shops but I got a good deal for it. And all you need from an IP phone is for it to boot up and work, the outside blemishes wouldn’t really matter. (For some but I hate scratches) I like buying from Craigslist. Simple, you can check it out before you buy it.

When I received my Cisco phones, one of the rear stands weren’t holding when you pull it down. Normally, it will lock in place but this you have to play with it til the lock goes in a certain position. This happens when someone does not know how to unlock the stand and forces it up or down. At that point, I really did not know the mechanics inside it and once I noticed that, I obsessed about it and the only thing I could think about was, “is it repairable?” I like repairing things and the feeling I get after I succeed! Again, it was time for me to research and learn. Google is my main resource nowadays. It is sad but it helps me learn.

I found exactly what I was looking for.

1998-2002 Honda Accord LED Vanity Mirror Lights

I do a lot of do-it-yourself when it comes to my car. Mainly because I like learning and it is a LOT cheaper. Mostly, it would just be small things like changing LED lights, fluids and drive belts. I’m not an expert but I try to read and learn before I touch anything. I don’t want to be stuck in the middle of nowhere because I messed with the mechanics of my car. So I am going to start with a very small project, converting your lights to LED for your vanity mirrors. I don’t know about you but I love bright lights so I changed mine to 6000k Xenon White LED.

I did this for my car which is a 2001 Honda Accord Coupe EX. I imagine it would be almost the same procedures for most cars but I could be wrong.  So let’s start!

These are the stock lights that came with the car.
