It is sometimes easy to confuse lines and calls. Use these tips to avoid confusion:
Lines--Lines support calls. To see how many lines you have, look at the line area of your phone screen. You have as many lines as you have extension numbers. You might have just one line.
Calls--Each line supports two calls. (That is why you might find yourself handling two calls, even though you have only one line on your phone.)
Note Only one call can be active at any given time. Other connected calls must be on hold. See the Using Hold and Resume topic .
