(rebinding timer) is used as per RFC 2131, Section 4.5
The 9600 Series IP Deskphones do not support Regular Expression Matching, and therefore,
do not use wildcards. For more information, see
Telephones on page 81.
In configurations where the upgrade script and application files are in the default directory on
the HTTP server, do not use the HTTPDIR=<path>.
- Option 242 - Site-Specific Option Number (SSON)
You do not have to use Option 242. If you do not use this option, you must ensure that
the key information, especially HTTPSRVR and MCIPADD, is administered
appropriately elsewhere.
An example of good DHCP administration is:
- Option 242 for DHCP: "MCIPADD=xxxx.xxx.xxx.xxx"
In Table 9, the 9600 Series IP Telephone sets the parameter values to the DHCPACK message
field and option contents shown.

Since the DHCP site-specific option is processed after the DHCP fields and standard options,
any values set in the site-specific option will supersede any values set via DHCP fields or
standard options, as well as any other previously set values. Values that can be set using the
DHCP site-specific option are listed in
Option on page 57.
Parameters L2Q, L2QVLAN, and PHY2VLAN are not set from a site-specific option if their
values were previously set by LLDP. For more information, see
(LLDP).
