## Chapter 1: Introduction

The Avaya IP Telephone File Server Application provides IP telephone support as well as administrative server support.

For the IP telephones, the application provides the following:

- An HTTP server to support:

- configuration file and firmware downloads to Avaya one-X Deskphone Edition 9600 Series IP Telephones,
- configuration file and firmware downloads to Avaya 4600 Series IP Telephones, and
- backup/restore of user-specific data for Avaya one-X Deskphone Edition 9600 Series IP Telephones.

- An HTTPS server to support:

- configuration file downloads to Avaya one-X Deskphone Edition 9600 Series IP Telephones, and
- configuration file downloads to Avaya 4600 Series IP Telephones.

- A TFTP server to support:

- configuration file and firmware downloads to Avaya 4600 Series IP Telephones.

- An FTP server to support:

- backup/restore of user-specific data for Avaya 4600 Series IP Telephones.

To support administrative functions, the application provides the following:

- Linux or Windows operating system versions run as Daemons/Services.
- Web-based status and administration capability.
- Detailed logging.
- TFTP “session” control for 4600 Series IP Telephones, to improve download reliability.
- SNMP lookup for anonymous, yet secure FTP login with zero administration, for 4600 Series IP Telephones only.
- IP address list control for selective downloading.
- Secure Web management option using HTTPS.
- Secure backup/update file server mode using TLS.
- Multi threading for server level performance.
- Optional “scanning” of installed IP Telephone firmware versions.

Combine the Avaya IP Telephone File Server Application with the DHCP functions of a RedHat Linux or Windows server for a single server solution for 4600 and 9600 Series IP Telephone system setup requirements.

Important: This document covers the 4600 Series IP Telephones and the 9600 Series IP Telephones. References to TFTP and FTP apply only to 4600 Series IP Telephones. References to HTTP and HTTPS apply to both series of telephones, except for HTTP backup/restore, which applies only to 9600 Series IP Telephones.

Figure 1: Operational Concept

There are specific application extensions to:

- Define which IP addresses can download software for initial, limited deployment testing.
- Proactively monitor the server with a dedicated WatchDog process.
- Provide a highly available server pair under Linux using HeartBeat.
- Unpack and distribute IP telephone firmware automatically using secure HTTPS protocol.
- Use secure HTTPS protocol to back up user data to central file servers.

The core File Server Application works with two optional supporting applications:

- MV_Manager, which provides Web-based administration, and
- MV_WatchDog, which monitors the health of the server application.
