One thing is the phones themselves.
I would have TLC (Tender Loving Care) Days for the phones, They can be the single biggest point of failure if any of them are dirty.
What I mean by TLC Days is:
-Establish a schedule to visit each facility.
-Once at the facility, visit each phone location and ask about missing button labels, and button caps or any other issues on each telephone set and fill into a spreadsheet. Determine which phones need to be replaced or repaired and take action.
-one phones are repaired or replaced, set up a cleaning TLC Day.
-Order a bunch of Paper Feature Cards for underneath the handsets on the M7000 sets or Feature Button Swinging arms/labels on the T7000 sets
Cleaning Day:
-Visit your local Walgreens and buy a ton of antibacterial wipes and an eyeglass lens cleaning cloth.
1.)Visit each phone extension
2.)Unplug Phone and handset
3.)Remove button caps or paper labels
4.)Vigorously wipe down all phones/handset/cords with antibacterial wipes, then finish the cleaning with a soft lens cleaning cloth to remove dust
5.)Wipe down all keycaps RLS Hold, etc (M7000 sets) to remove dirt and grime....
6.)Place handset, cords, keycaps and labels back on telephone
7.)Power phone back on and set on your users desk....they will be like "Who installed a new phone for me overnight?"
It's really that simple to get the maximum value out of your Nortel handsets. Keeping them clean, free of damaging dirt/grime/spilled soda and fresh looking will carry them well into the future.
Note: On T7000 series phones with paper labels, use double stick tap on the back side of the label, so that if the plastic label desi cover strip ever falls off, the labels will still be there.
I've done this cleaning method for hundreds of Nortel users and they always think they just got a new phone system.
TLC Days for Nortel Phones!
