4.3 Programming the Virtual Extension Card and IP Telephones
For SIP Extensions
1.
Using a DHCP server to automate the assignment of IP addressing information
The IP address of the SIP Extension, the subnet mask address, and the default gateway address can
be assigned to the SIP Extension automatically by the DHCP server.
The PBX IP address must be assigned manually on the SIP Extension side.
For instructions, refer to the documentation of the SIP Extension.
2.
Not using a DHCP server when assigning IP addressing information
All the IP addressing information must be assigned manually.
For instructions, refer to the documentation of the SIP Extension.
Notes
• SIP Extensions can only receive IP addressing information from a DHCP server on its own LAN.
Therefore, when SIP Extensions are located on several LANs, a DHCP server is required on each
LAN.
• When the DHCP client function is enabled for SIP Extensions, simply connect the SIP Extensions
to the LAN to use the DHCP server. For the DHCP client function setting, refer to the
documentation of the SIP Extension.
