Chapter 4 Basic and Additional SIP Services

Additional SIP Services

Establishing Authentication

The UseLoginID parameter lets you select the user ID for authentication of the phone to the remote end as follows:

If UseLoginID is set to 0, the user ID (set with the UID parameter) is used with a user-supplied password (set with the PWD parameter) for authentication.

If UseLoginID is set to 1, you must supply a login ID (set with the LoginID parameter) and a password (set with the PWD parameter) for authentication.

Configuring Refresh Interval

When the value specified with the CfgInterval parameter is reached, the

Cisco IP Phone attempts to refresh its configuration file from the TFTP server. (You can manually perform a refresh before the scheduled refresh as explained in the “Refreshing the Cisco IP Phone” section on page 6-17.)

When a Cisco IP Phone contacts the TFTP server, it also checks to see if a firmware image has been placed on the TFTP server. If such an image exists, the phone will download this image.

Additional SIP Services

Table 4-2describes additional SIP services and provides references to additional information. These services are listed alphabetically.

Note Many of the descriptions in Table 4-2refer to specific parameters that you can set in a profile or from a phone’s web page. For the corresponding parameter in the phone configuration menus, see Appendix B, “Phone Menu, Web Page, and Profile Equivalent Parameters.”
