IP Network Parameters
3.3.2
Use DHCP
If this parameter is set to "Yes" (default), the phone will search for a DHCP server on startup
and try to obtain IP data and further configuration parameters from that central server.
If no DHCP server is available in the IP network, please deactivate this option. In this case, the
IP address, subnet mask and default gateway/route must be defined manually.
The following parameters can be obtained by DHCP:
Basic Configuration
•
IP Address
•
Subnet Mask
Optional Configuration
•
Default Route (Routers option 3)
•
IP Routing/Route 1 & 2 (Static Routes option 33)
•
SNTP IP Address (NTP Server option 42)
•
Timezone offset (Time Server Offset option 2)
•
Primary/Secondary IP Addresses (DNS Server option 6)
•
DNS Domain Name (DNS Domain option 15)
•
SIP Addresses / SIP Server & Registrar (SIP Server option 120)
•
Vendor Unique (option 43)

With firmware version V2R1 onwards, the phone is able to maintain its IP connection
even in case of DHCP server failure. For further information, please refer to Section
2.3.4, “DHCP Resilience (V2R1)”.
