*NOTE about “Flash” or “Flash Hook”
In this document reference will be made to perform a function called “Flash”. This is a 250ms break in the established connection that lets the Voice Switch know that you want to perform a special function of the feature you want to use. On most feature phones there is a button labeled “Flash” or “Link”. On phones that don’t have a button you can depress the cradle button where the handset normally sits in an idle condition for ¼ of a second. This will not disconnect the active call if done correctly.
