H.323 IP Phone Installation

Last Updated : Jul 12, 2021 |

The following is a summary of the major steps in the installation process. The recommended installation method is to use DHCP where possible, to use the IP Office system as the file server and to enable automatic user and extension creation.

Description

Manager PC:

Check that IP Office Manager, System Status Application and System Monitor are installed and can be used to connect to the IP Office system. Verify that you can receive the configuration from the system and send it back.

Voice Compression Channels

For IP500 V2 systems, the control unit must be fitted with voice compression channels . Use either System Status Application (SSA) or System Monitor application to verify that the voice compression channels are available. SSA list the Voice Compression Modules (VCM) channels on the Resources screen. The initial lines of Monitor output include the item VCOMP= which states the number of channels installed in the control unit.

Licenses or Subscriptions

Depending on the system's operating mode, each phone requires a license or subscription. Phones without a license or subscription can register but will not operate. See Licenses and Subscriptions.

H.323 Gatekeeper Settings

The IP Office system has support for H.323 phones enabled by default. However, the setting should be checked.

DHCP Server Setting

DHCP is the recommended method for installation of IP phones on a IP Office system. This requires a DHCP server configured to support IP phones. The IP Office system can be used for this. If the customer want to use their own DHCP server, it requires additional configuration

Phone File Server Setting

If the IP Office system is being used for DHCP, it also needs to be configured with the address of the file server. Whichever installation method and file server is selected, the phone firmware files need to be added to the files available on the server.

Extension and User Settings

The IP Office system can be configured to automatically create user and extension entries in its configuration for each IP phone that is installed. It automatic creation is not used, entries must be manually created for each extension and user before the phones are installed.

Phone Connections

Once the steps above have been completed, the phones can be connected to the network. If using DHCP, the phones will automatically obtain IP address information and other settings and then start loading files. If not using DHCP, the phones will have to be taken through a manual process of entering the IP address information and settings.

Phone Registration

Once the phones have downloaded all the files they require from the file server, they will attempt to register with the IP Office system. The phones will prompt for entry of the extension number that they should use.

Testing

Operation of the phones should be tested by making a number of calls, including external calls.

Post Installation

If auto-creation was used for the extension and or user entries, those settings should be disabled after installation of all the phones is completed. This manual only details the minimum user configuration necessary for installation. The new users can now be fully configured to meet the customer requirements for those users.
