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.
