Connecting the Telephone to the 3Com Asterisk Appliance
Connect your telephone to power and to the LAN as described in
Connecting the Telephone.
Your Asterisk administrator must assign you a user account that includes
your telephone extension and your username and password. Before the
telephone can connect to the 3Com Asterisk Appliance, it must have
these IP configuration settings defined:
■The telephone IP address
■The subnet mask of your local network
■A default gateway IP address
■The IP address of the 3Com Asterisk Appliance and the IP address of
the download server
If your network is configured to use DHCP, the telephone receives its IP
configuration automatically. Otherwise, you must configure your
telephone manually for network and 3Com Asterisk Appliance
connectivity.
