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

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 following 
section, 
. If the DHCP server sends nothing, the 
phone sends out a DHCP INFORM query and the following 
scenarios are possible: 
If no alternate DHCP server responds:
- The INFORM query process will retry and eventually time 
out.
- The boot server value stored in flash will be used.
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.
