Network Assessment

A network assessment must be completed. Avaya will not support VoIP on a network where a satisfactory network assessment has not been obtained.

Extension Number and User Details

A full listing of the planned extension number and user name details is required. The planned extension number must be unused and is requested by the phone during installation.

Power Supplies

Each phone requires a power supply. Avaya IP phones do not draw power from the IP Office. A number of options exist for how power is supplied to the phones and all the Avaya IP deskphones support Power over Ethernet (PoE). See Power Supply Options

LAN Socket

An RJ45 Ethernet LAN connection point is required for each phone.

Category 5 Cabling

All LAN cables and LAN cable infrastructure used with H.323 IP phones should use CAT5 cabling.

LAN Cables

Check that an RJ45 LAN cable has been supplied with the IP phone for connection to the power supply unit. You may also need an additional RJ45 LAN cable for connection from the power unit to the customer LAN. This will depend on the type of power supply being used.

A further RJ45 LAN cable can be used to connect the user's PC to the LAN via the IP phone (not supported on 4601, 4602, 5601 and 5602 H.323 IP phones).

Voice Compression Channels

For IP500 V2 systems, the control unit must have voice compression channels installed. Channels are required during the connection if calls involving IP phones and may also be required during the call. See Voice Compression Channels for full details.

DHCP Server

The IP Office Unit can perform this role for all the phones. If another DHCP server is used for the network, this may be able to do DHCP for the H.323 IP phones, see Alternate DHCP Servers . Also the IP Office system can be configured to only provide DHCP support to Avaya IP phones.

HTTP File Server

A PC running the IP Office Manager application can perform this role for up to 5 H.323 IP phones. An IP Office control unit with a memory card can use that memory card as the source for up to 50 phones. The IP Office system can act as the file server for up to 50 IP phones. For larger numbers a separate 3rd-party HTTP server should be used.

H.323 Gatekeeper

The IP Office system performs this role.

Manager PC

A Windows PC running IP Office Manager is required for IP Office configuration changes. The PC should also have System Status Application and System Monitor installed.

IP Telephone Software

The software for IP phone installation is installed into the IP Office Manager application's program folder as during the applications installation. It is also included as part of the IP Office Server Edition applications installation of the IP Office application on the server.

Licenses and Subscriptions

For systems not running in subscription mode, each IP phones registered with the system requires an license to operate. On subscriptions mode systems, the extension must be associated with a subscribed user. Refer to Licenses and Subscriptions

Backup/Restore Server

The phones backup and restore various phone and user settings whenever the user logs on or logs out. This uses files stored on a file server. This is not necessarily the same server as used for the phone firmware files. The IP Office system's own file storage can be used for this function and is the recommended option.
