IP Phone Installation
15 – 6 ShoreTel, Inc.
NOTE When using the Microsoft DHCP server, you must enter the time offset that is
provided to the IP phones in hex (hexadecimal) if the offset is negative. If you
enter a negative number in decimal, the DHCP server software modifies the
entry to be the positive number of the same magnitude or the absolute value
before storing the value in hex. For example, if the desired offset is -8 hours or -
28800 seconds, you enter the hex value of 0xFFFF8F80.
-8 hr = 0xFFFF8F80
-7 hr = 0xFFFF9D90
-6 hr = 0xFFFFABA0
-5 hr = 0xFFFFB9B0
IP Address Assignment
When a single DHCP server is used for IP phones in multiple sites, the DHCP server
must be configured to provide IP addresses for the telephones at different sites based on
the location or subnet where the telephone that issues the DHCP request is located.
The assigned addresses for each site or subnet should correspond to the IP address
range configured for each site in the IP Phone Address configuration in ShoreWare
Director.
Associating a User Group with Unassigned IP Phones
Unassigned IP phones are available for users configured for Any IP Phone. Select the
user group that will have access to unassigned IP phones from the pull-down list.
Since unassigned IP phones are not associated with a user, you cannot report on calls
made from these telephones and associate them with an individual user. It is
recommended that unassigned IP phones be configured with a class of service with
minimal calling privileges.
