135.254.76.90 to 135.254.76.200

135.254.76.225 to 135.254.76.230

The Start IP address and End IP address you enter in the IP Address Range dialog box are 135.254.76.7 and 135.254.76.230 respectively.

In the Add Exclusions dialog box, exclude the following ranges:

135.254.76.81 to 135.254.76.89

135.254.76.201 to 135.254.76.224

Click the Next button after you enter all the exclusions. The Lease Duration dialog box displays.

10.For all telephones that obtain their IP addresses from the server, enter 30 days in the Lease Duration field. This is the duration after which a device’s IP address expires and which the device needs to renew.

11.Click the Next button.

The Configure DHCP Options dialog box displays.

12.Click the No, I will activate this scope later button. The Router (Default Gateway) dialog box displays.

15.Highlight the newly created scope and select Action-->Propertiesfrom the menu.

16.Under Lease duration for DHCP clients, select 2 weeks (minimum) and click the OK button.

! CAUTION:

IP address leases are kept active for varying periods of time. To avoid having calls terminated suddenly, ensure that the lease duration is not too short, for example, not set to less than two weeks. A lease duration of two to four weeks is reasonable.
