Why each option
The dual-line command under an ephone-dn enables that directory number to handle two simultaneous calls or lines.
There is no 'ephone 1 lines 2' command - the lines parameter is not a valid option under the ephone configuration context.
'ephone-dn 1 lines 2' is not valid IOS syntax; the correct keyword for dual-line support is 'dual-line', not 'lines 2'.
The command 'ephone-dn 1 dual-line' entered in ephone-dn configuration mode configures the directory number to support two lines, allowing it to handle two simultaneous call appearances. This is the correct Cisco IOS SRST/CME syntax for enabling dual-line behavior on a DN. Without this command, the ephone-dn defaults to single-line mode.
'ephone-dn 1 secondary line add' is not a valid IOS telephony-service command.
Concept tested: CME ephone-dn dual-line configuration command
