Software Checklist

Note:

!
CAUTION:
CAUTION:
The firmware in the 1603SW-I IP Deskphones reserves IP addresses of the form
192.168.0.24 and 192.168.1.x for internal communications. The deskphone(s)
improperly use addresses you specify if they are of that form.
DHCP and File Servers
Dynamic Host Configuration Protocol (DHCP) minimizes maintenance for a 1603SW-I SIP IP
Deskphone network by removing the need to individually assign and maintain IP addresses and
other parameters for each IP telephone on the network.
The DHCP server provides the following information to the 1603SW-I SIP IP Deskphones:
●
IP address of the 1603SW-I SIP IP Deskphone(s)
●
IP address of the HTTP or HTTPS server
●
IP address of the NTP (Network Time Protocol) server (using Option 42)
●
The subnet mask
●
IP address of the router
●
DNS Server IP address
Administer the LAN so each SIP deskphone can access a DHCP server that contains the IP
addresses and subnet mask.
