Large Installation (More than 5 phones)

The diagram below shows a scenario where more than 5 IP telephone devices are being supported. In
this scenario the DHCP and TFTP roles must be changed from those used in a "small installation".
• DHCP Server
In this scenario a separate DHCP server is being used. This requires that the DHCP function of
the IP Office control unit is switched off. Therefore the IP Office control unit must be given a fixed
IP address (or act as a DHCP client). Details of using a Windows 2000 DHCP Server are
included in this documentation but those details are applicable to most DHCP servers.
• H.323 Gatekeeper
The IP Office control unit is acting as the H.323 Gatekeeper for the H.323 IP phones.
• TFTP Server
In this instance, the Manager role as TFTP server must be replaced by an alternative TFTP
Server option. The installation process includes details for doing this in several ways:
•
On Small Office Edition and IP406 V2 control units, a memory card in the Embedded
Voicemail Memory card slot can be used as the TFTP folder.
• A 3rd party TFTP application can be installed and used.
