Simple Installation - Avaya IP Office H.323 Telephone Installation Manual

1.4 Simple Installation

The diagram below shows the simplest installation scenario. This has the IP Office system acting as the DHCP and file
servers for all the IP phones registered with it.
This type of installation uses the following equipment:
· IP Office Server
The IP Office system performs a number of roles for the phones:
· DHCP Server
The IP Office system is acting as the DHCP server for the phones. The DHCP response to the phones includes
both IP address settings, details of the file server to use as configured in the IP Office configuration and the
systems on address as the H.323 gatekeeper for the phones. The IP Office DHCP function can be configured
to provide DHCP addresses only in response to requests from Avaya IP phones. This allows an alternate DHCP
server to be used for other devices that use DHCP.
· H.323 Gatekeeper
IP phones require an H.323 gatekeeper to which they register. The gatekeeper then controls the connection of
calls to and from the phone. In this and all scenarios the IP Office systems as the H.323 Gatekeeper.
· File Server
During installation the IP phones need to download
HTTPS, HTTP or TFTP in that order (1600 and 9600 Series phones do not support TFTP). If the IP Office
control unit is fitted with a memory card (mandatory on IP500 v2 control units), that card can be used as the
file source.
· The IP Office system can use its own memory card to act as the file server for up to 50 phones. For larger
numbers a separate 3rd-party HTTP server should be used.
· The IP Office system is currently not supported as a file server for 9608, 9611, 9621, and 9641 phones.
This also applies to using the IP Office Manager application acting as the file server. These phones are
only supported when using a 3rd-party file server.
Backup/Restore Server
·
1600 Series and 9600 Series phones can be configured to backup and restore user and phone settings to a
server. The address of this server is set separately from that of the file server used for phone firmware
though the same server may be useable. The recommended method is to us the IP Office system as the
server for this function.
· Switches
The IP Office has a limited number of LAN connection ports, intended only to connect itself to the existing data
network. The addition of IP phones will require the network to include additional port capacity.
Power Supplies
·
Each H.323 IP phone requires a power supply. The IP Office system does not provide any power to IP phones. The
phones can be
· Power over Ethernet Supply
Most Avaya IP phones can be powered from an 802.3af Power over Ethernet (PoE) power supply. This can be
done using PoE switches to support multiple phones or using individual PoE injector devices for each phone.
· Individual Power Supply Units
An individual power supply unit can be used with each phone. This will require a power supply socket at each
phone location. Note that for phones using a button module add-on, for example a EU24 or BM32, an
individual power supply unit is often a requirement. The type of power supply will depend on the type of
phone.
