 Setting up Your System

3 - 7

The DHCP menu is accessible only when the DHCP client is enabled. The 
following DHCP configuration parameters can be modified on the DHCP 
menu:

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.

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.

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 following 

. 

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.
