After you install Cisco Unified IP Phones in your network, configure their network settings, and add them to Cisco Unified Communications Manager, you must use the Cisco Unified Communications Manager Administration application to configure telephony features, optionally modify phone templates, set up services, and assign users.
This chapter provides an overview of these configuration and setup procedures. Cisco Unified Communications Manager documentation provides detailed instructions for these procedures.
To list supported features for all phones or for a particular phone model on your Cisco Unified Communications Manager, you can generate a Unified CM Phone Feature List report on Cisco Unified Reporting.
For suggestions about how to provide users with information about features, and what information to provide, see Cisco IP Phone User Support.
For information about setting up phones in non-English environments, see International User Support.
If you are a system administrator, you are likely the primary source of information for Cisco IP Phone users in your network or company. It is important to provide current and thorough information to end users.
To successfully use some of the features on the Cisco IP Phone (including Speed Dial, Services, and voice message system options), users must receive information from you or from your network team or must be able to contact you for assistance. Make sure to provide users with the names of people to contact for assistance and with instructions for contacting those people.
We recommend that you create a web page on your internal support site that provides end users with important information about their Cisco IP Phones.
Consider including the following types of information on this site:
Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing, conference calling, and voice messaging system access. Cisco Unified IP phones also provide a variety of other features.
As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure on a phone, but if your network requires it, you can manually configure an IP address, TFTP server, subnet information, and so on.
Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status information from it directly. This information can assist you with troubleshooting any problems users might encounter when using their IP phones.
You can modify additional settings for the Cisco Unified IP Phone from Cisco Unified Communications Manager Administration. Use Cisco Unified Communications Manager Administration to set up phone registration criteria and calling search spaces, among other tasks. See the "Telephony Features" section in this document and the Cisco Unified Communications Manager documentation for additional information.
For more information about Cisco Unified Communications Manager Administration, see the Cisco Unified Communications Manager documentation, including Cisco Unified Communications Manager Administration Guide. You can also use the context-sensitive help available within the application for guidance.
After you add Cisco Unified IP Phones to Cisco Unified Communications Manager, you can add functionality to the phones. The following table includes a list of supported telephony features, many of which you can configure using Cisco Unified Communications Manager Administration.
For information about using most of these features on the phone, see the Cisco Unified SIP Phone 3905 User Guide for Cisco Unified Communications Manager.
![]() Note | Cisco Unified Communications Manager Administration also provides several service parameters that you can use to configure various telephony functions. For more information on accessing and configuring service parameters, refer to Cisco Unified Communications Manager Administration Guide. For more information on the functions of a service, select the name of the parameter or the question mark help button in the Service Parameter Configuration window. |
