This lab provides brief explanation of what we did and the commands we used in this lab. This lab is setup and configured very similar to one of our lab on the CNT 2722 course.

Ephone and Ephone-DN

• Ephone Directory Number with dual line enabled. Some advanced settings only available on dual-line enabled mode. For example, A single-line phone can make or receive only one call at a time. If the line is already in use, you cannot place the call on hold to make a second call. Meaning that if line 1 is in use, a second phone call to the extension will receive a busy signal. However, dual-line phones, on the other hand, allow the phone to place calls on hold or receive a second call when in use.
