From the maual...

"Full AutoHold on idle line is a variation of the Automatic Hold feature. If
you select an idle line, but do not dial any digits, that line is automatically
placed on hold if you then select another line."

And

Tip - The default setting should be changed only if FullAutoHold is required for a specific application. For instance, if you define system-wide access keys (SWCA)for telephones, Full AutoHold must be active on those telephones for the feature to act correctly.
