is 101: R1-PBX(config-ephone-dn)#number 101 Small-Office VolP Example Cisco SYSTEMS CISCO IP PHONE 7970 SERIES 12 46a 01/27/11 Office Lauren Meghan Colleen Outside-Line GAD Technology Redial NewCall CFwdAll PickUp Figure 30-4. Cisco 7970 phone; the line key buttons are on the right You can assign multiple numbers to a line using the secondary keyword as follows: R1-PBX(config-ephone-dn) #number 101 secondary 9735554333 We won't use the secondary feature, though, SO we're just going to stick with number 101 for now. There are multiple ways in which we can describe this line: label, description, and name. The label will be what appears next to the button on your phones. The description is the DN Qualified Display Name, which appears on the top of the phone when assigned to the first button. The name is the DN username that appears on other phones re- ceiving calls from this number. In Figure 30-4, you can see that the first button is labeled as GAD. Here's how we make that happen: R1-PBX(config-ephone-dn)#label GAD Looking again at Figure 30-4, notice that the top of the display says Office. This is displaying the DN Qualified Display Name for the first configured line. We configure this with the description command: 21-PBX(config-ephone-dn)#description Office I've configured voicemail to answer extension 222, SO now I'll configure this line to forward to voicemail. There are two important times that voicemail should be auto- matically invoked: when the line is busy and when the line is not answered. Both are configured with the call-forward command: Chapter 30: VolP R1-PBX(config-ephone-dn)# call-forward busy 222 R1-PBX(config-ephone-dn)# call-forward noan 222 timeout 10 The number after the timeout keyword is the number of seconds that the system will wait until forwarding an unanswered call. This doesn't have to be to voicemail-we can just as easily forward to another user's extension if we want to. I've configured the remaining lines in a similar fashion. Here's the configuration for all four user lines: ephone
