404 Avaya Application Solutions IP Telephony Deployment Guide
The implication of this fact can be seen in the following example. Assume two IP addresses
(hence two possible DHCP leases) and three IP Telephones, two of which are using the two
available IP addresses. When the lease expires for the first two telephones, the third will not
be able to get a lease (even if the other two telephones have been removed from the
network), until the reservation period expires.
The IP Telephone sets the indicated system values to the values of the indicated fields of
the DHCPACK message (
Table 91
).
