In CallManager Express, you add an IP phone in two steps:
Step 1. |
You add the physical IP phone using the ephone configuration mode. In this step, you define the physical attributes of the phone so that it can register with CallManager Express. Each IP phone, or ephone, can have multiple lines. |
Step 2. |
You define the lines using the ephone-dn configuration. In this step, you assign the extension that is associated with the line. In CallManager Express, lines, or extensions, are often referred to as ephone-dns. |
When you are running Cisco CallManager Express, you assign incoming COR lists to your IP phones under the ephone-dn configuration. Because the COR lists are assigned to the ephone-dn, you can configure different calling privileges on a single IP phone. Example 12-2 illustrates how to assign incoming COR lists to ephone-dns.
Leeds(config)#ephone-dn 1 Leeds(config-ephone-dn)#description Leeds Admin Leeds(config-ephone-dn)#number 4005 Leeds(config-ephone-dn)#cor incoming Employees ! Leeds(config)#ephone-dn 2 Leeds(config-ephone-dn)#description Leeds Manager Leeds(config-ephone-dn)#number 4010 Leeds(config-ephone-dn)#cor incoming Managers ! Leeds(config)#ephone-dn 3 Leeds(config-ephone-dn)#description Leeds Executive Leeds(config-ephone-dn)#number 4050 Leeds(config-ephone-dn)#cor incoming Executives |
You can also assign outgoing COR lists to an ephone-dn to restrict who can call an IP phone. This requires additional labels to maintain compliance with the guidelines for configuring COR. The section "Restricting Inbound Calls" discusses this in more detail.
Assigning COR Lists to SIP Phones with CallManager Express
CallManager Express 3.4 added support for SIP phones. SIP phones are defined using the voice register dn dn-tag and the voice register pool pool-tag commands. You can assign incoming and outgoing COR lists under the voice register pool configuration. Assigning COR lists to SIP phones is similar to assigning COR lists to SRST phones. You can assign COR lists to a single SIP directory number or to a range of numbers using the following command:
[View full width]
cor {incoming | outgoing} cor-list-name {cor-list-number starting-number [- endingnumber] | default}
Example 12-3 illustrates how to assign COR lists to SIP phones in CallManager Express.
Leeds(config)#voice register pool 1 Leeds(config-register-pool)#id mac 000D.ED22.ED33 Leeds(config-register-pool)#type 7960-7940 Leeds(config-register-pool)#number 1 dn 1 Leeds(config-register-pool)#cor incoming Executives 1 4060 |
