Which of the following commands should you issue to set the maximum number of extensions that you can configure on a CME router? (Choose two.)
- ephone
- ephone-dn
- max-dn
- max-ephones
- telephony-service
- dnwebedit
Explanation:
You should issue the telephony-service command and the max-dn command to set the maximum number of directory numbers (dns), or extensions, that you can configure on a Cisco Unified Communications Manager Express (CME) router. Issuing the telephony-service command puts the router into telephony-service configuration mode, where you can issue commands that configure telephony settings on the router, such as the max-dn and max-ephones commands.
A CME router requires three values in order to configure basic telephony service: an IP address, a max-dn value, and a max-ephones value. The maximum value of the max-dn parameter varies based on the router model, the IOS version, and the amount of memory. If you do not issue the max-dn command, you will not be able to configure any ephone-dns on the router.
You should issue the dn-webedit command to enable the addition of ephone-dns by using the browser-based graphical user interface (GUI). By default, you cannot add an extension to CME by using the browser-based GUI. The dn-webedit command should be issued in telephony-service configuration mode.
You should issue the max-ephones command to set the maximum number of phones, not the maximum number of extensions, that you can configure on a router. Like the max-dn command, the max-ephones command must be issued in telephony-service configuration mode. The maximum value of the max-ephones parameter varies based on the router model and the IOS version. If you do not issue the max-ephones command, you will not be able to configure any ephones on the router.
You cannot issue the ephone-dn command to set the maximum number of extensions that you can configure on a router. The ephone-dn command configures an ephone-dn. The syntax of the ephone-dn command is ephone-dn dn-tag [dual-line | octo-line]. Issuing the ephone-dn command puts the router into ephone-dn configuration mode. To set the extension number for an ephone-dn, you should issue the number command in ephone-dn configuration mode.
You cannot issue the ephone command to set the maximum number of extensions that you can configure on a router. The ephone command configures an ephone. The syntax of the ephone command is ephone phonetag. Issuing the ephone command puts the router into ephone configuration mode. To associate a physical IP phone with an ephone, you should issue the ma-caddress mac-address command in ephone configuration mode, where mac-address is the Media Access Control (MAC) address of the IP phone.
