IP Phone Administrator Guide

The firmware setup and installation for the IP phone can be done using any of the 
following:

•

Phone keypad menu (Phone UI)

•

Aastra Web-based user interface (Aastra Web UI)

When the IP phone is initialized for the first time, DHCP is enabled by default. 
Depending on the type of configuration server setup you may have, the IP phone 
may download a firmware version automatically, or you may need to download it 
manually.

The following considerations must be made before connecting the IP phone to the 
network:

•

If you are planning on using dynamic IP addresses, make sure a DHCP server 
is enabled and running on your network. 

•

If you are not planning on using dynamic IP addresses, see Chapter 4, the 
section, 

 for manually 

setting up an IP address.

To install the IP phone hardware and cabling, refer to the model-specific 
SIP IP Phone Installation Guide.
