Administering Options for the 4600 Series IP Telephones

As indicated in the Introduction of this chapter, there are many parameters that can be administered for the 4600 Series IP Telephones. This section explains how to change parameters via the DHCP or TFTP servers. In all cases, you will be setting a system parameter in the telephone to a desired value. Table 4-5 lists the parameter names, their default values, the valid ranges for those values, and a description of each one. For DHCP, the parameters below are set to desired values in the DHCP Option, as discussed in DHCP Generic Setup earlier in this chapter. For TFTP, the parameters below are set to desired values in the TFTP Script File, as discussed in Contents of the Upgrade Script also earlier in this chapter.

TFTP Scripts are the recommended way to administer options on the 4600 Series IP Telephones. Some DHCP applications have limits on the amount of user-specified information; such limits could be exceeded by the administration required, for example, a 4630 with all applications administered.

You may choose to completely disable the capability to enter or change option settings from the dialpad, as of Release 1.8. As of that Release, a new system value, PROCPSWD, can be set as part of standard DHCP/TFTP administration. If PROCPSWD is non-null and consists of 1 to 7 digits, no local procedures (“dialpad options”) can be invoked unless the user enters the value of PROCPSWD after pressing Mute or Hold (see “Chapter 3" of the 4600 Series IP Telephone Installation Guide) and before entering the local procedure code.


NOTE:	Because this password is likely stored on the server “in the clear” and is certainly sent to the telephone in the clear, you should not consider PROCPSWD as a high-security technique to inhibit a sophisticated end-user from obtaining access to the local procedures. Administering this password disables all local procedures, including V I E W, which is read-only and would not change any settings in any case.

NOTE:	Table 4-5 applies to all 4600 Series IP Telephones. The 4630/4630SW and 4620 IP Telephones have additional, optional administration. See Customizing the 4630/4630SW IP Telephone and Customizing the 4610SW/4620/4620SW IP Telephones, below, for more information.
