x_displayname
(Phone-specific; optional) Identification as it should appear for caller-identification purposes. For example, instead of jdoe@company.com appearing on phones that have caller ID, you can specify User A in this parameter to have User A appear on the called party display. If a value is not specified for this parameter, nothing is used.
The x argument can be 1 or 2.
linex_name
(Phone-specific) Number or e-mail address for use when registering. Enter a number without dashes. For example, enter 555-0100 as 5550100. Enter an e-mail ID without the host name. The x argument can be 1 or 2.
linex_password
(Phone-specific; optional) Password used by the phone for authentication if a registration is challenged by the proxy server during initialization. If a value is not configured for the linex_password parameter when registration is enabled, the default password is used. Default is UNPROVISIONED.
Valid values for x are (Cisco IP 7969G phone) 1 to 6 and (Cisco IP 7940G phone) 1 to 2.
