DHCP Menu
The DHCP menu is accessible only when the DHCP client is enabled. The
following DHCP configuration parameters can be modified on the DHCP
menu:
Note A parameter value of “???” indicates that the parameter has not yet been set and
saved in the phone’s configuration. Any such parameter should have its value set
before continuing.
The EM Power parameter is only available on SoundPoint IP 601 and 650 phones.
Note To switch the text entry mode on the SoundPoint IP 330/320, press the #. You may
want to use URL or IP address modes when entering server addresses.

Values
Description
Timeout 1 through 600 Number of seconds the phone waits for secondary DHCP Offer
messages before selecting an offer.
Boot Server 0=Option 66 The phone will look for option number 66 (string type) in the
response received from the DHCP server. The DHCP server
should send address information in option 66 that matches one
of the formats described for Server Address in the next
section,
Server Menu .
If the DHCP server sends nothing, the following scenarios are
possible:
• If a boot server value is stored in flash memory and the
value is not “0.0.0.0”, then the value stored in flash is used.
• Otherwise the phone sends out a DHCP INFORM query.
- If a single alternate DHCP server responds, this is
functionally equivalent to the scenario where the primary
DHCP server responds with a valid boot server value.
- If no alternate DHCP server responds, the INFORM query
process will retry and eventually time out.
