WLAN IP Telephony Installation and Configuration
IP addressing with DHCP
A pool of alias IP addresses must be configured on the WLAN IP Telephony
Manager 2245 for the use of the wireless handsets. The use of a 22-bit subnet
mask provides IP addresses for approximately 500 wireless handsets (1024
nodes). Allocate a pool of an equal number of IP addresses on the DHCP
server for the wireless handsets.
For example:
142.223.204.1 to 142.223.205.254 are allocated on the DHCP Server for the
use of the wireless handsets.
142.223.206.1 to 142.223.207.254 are configured on the WLAN IP
Telephony Manager for IP aliases for the wireless handsets.
Ensure that all these IP addresses are reserved on the DHCP Server for the use
of the wireless handsets and not assigned to any other device.
