dual-line dual-line DN (2 calls per line/button)

CME_Voice(config)#
ephone-dn 2 dual-line
CME_Voice(config-ephone-dn)#
number 1001
That's all there is to it! Notice the range of ephone-dn tags from the context-sensitive help
is 1-150. This tag is a logical number, which is used when assigning the ephone-dn to an
ephone. You can choose any ephone-dn tag from the range when creating the ephone-dn
as long as the total number of ephone-dns does not exceed the number specified using the
max-dn command.
Note:
Creating more ephone-dns than you have specified using the
max-dn
command
results in the following error message:
CME_Voice(config)# ephone-dn 49
dn tag 49 exceeds legal range 1 to max-dn 48
To correct this error, increase the max-dn value from telephony service configuration mode.
The number syntax (which is used to assign a directory number to an ephone-dn) also
supports a secondary number value. For example, you can enter the following:
CME_Voice(config)#
ephone-dn 2 dual-line
CME_Voice(config-ephone-dn)#
number 1001 secondary 4805551001
This enables the ephone-dn to answer for multiple phone numbers. This can be used if
you want an internal extension to be reachable if someone on the internal network dialed
a four-digit extension or the full Public Switched Telephone Network (PSTN) Direct In-
ward Dial (DID) number.
Note:
DID is a feature supported by PSTN carriers that enables internal extensions to be
reached by PSTN callers directly without the need to route calls through a receptionist.
Understanding and Configuring Ephones
When you configure an ephone in CME, it represents the configuration applied directly to
a single Cisco IP Phone or SoftPhone managed by the CME router. Just as with the ephone-
dns, the max-ephone parameter directly impacts the number of ephones you are able to
create and manage on a CME router. Example 5-6 adds an ephone to the CME router.
Example 5-6
