IP Office H323 IP Phones: Phone Firmware
1.5 Simple Installation
The diagram below shows a simple installation scenario that can be supported by all IP Office systems running IP Office Release 6.
This type of installation uses the following equipment:
∙IP Office
The IP Office control unit is performing a number of roles for the phones:
∙DHCP Server
The IP Office unit is acting as the DHCP server for the Avaya IP phones. Key settings such as the file server address are entered into the IP Office configuration and then provided to the phones in addition to their IP address.The IP Office DHCP server 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.
∙The IP Office control unit can provide DHCP support for up to 272 phones. Alternatively a separate DHCP server can be used.
∙H323 Gatekeeper
IP phones require an H323 gatekeeper to which they register. The gatekeeper then controls connecting calls to the phone. In this scenario the IP Office control unit acts as the H323 Gatekeeper.
∙File Server
During installation the IP phones need to download software and settings files for a file server. 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 control unit with memory card can act as the file server for up to 50 phones. Alternatively a
∙Switch
The IP Office control units have limited numbers of LAN connection ports. They are intended to be connected to a LAN switch with port capacity for the customers network equipment.
∙Power Supplies
Each H323 IP phone requires a power supply.
∙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
∙Power over Ethernet Supply
Most Avaya IP phones can be powered from an 802.3af Power over Ethernet (PoE) power supply. The IP Office system does not provide PoE ports so a separate PoE switch or PoE injector devices will be required to power a phone using PoE.
