If you have two phone
lines
If you have subscribed to a second phone line (see “Work with two phone
lines” on page 35), call timers are separate for each of your phone lines.
When you view call timers, the call timers that are shown are for the
currently selected outgoing line. However, if you view call timers while
you are in a call, the call timers that are shown are for the line you are
using at that moment.
