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.

in a profile or from a phone’s web page. For the corresponding parameter in the
