Communicate clearly using the Nato phonetic alphabet background. It is difficult to accurately convey an asset tag, serial number, model number, etc to a peer or offsite support. Aside from phone clarity there is often accent or language barriers.

If you are using a Microsoft Windows OS you can quickly add the Nato phonetic alphabet to your desktop background. Grab a copy of the Sysinternals tool Bginfo. Then download the nato.bgi configuration file.
