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.

ephone-dn 1 dual-line
