What procedure is used to install new binary files for Avaya IP phones during a software upgrade?

The correct procedure for installing new binary files for Avaya IP phones during a software upgrade involves the phones receiving new firmware using HTTP. This method utilizes the Hypertext Transfer Protocol (HTTP), allowing the phones to download the necessary files from a designated server when they boot up or during an upgrade process. Avaya IP phones are typically configured to communicate with a specific firmware server where the latest firmware is stored, enabling them to fetch and install updates seamlessly.

This method is widely adopted in network environments for its efficiency in delivering updates to devices on the network. Not only does HTTP provide a straightforward approach to file transfer, but it also allows for easy management and version control of the firmware files. By leveraging this protocol, users can ensure that their phones are running the latest software necessary for optimal performance and security.

Other methods mentioned, while potentially valid in different contexts, do not specifically align with the commonly used procedure for Avaya IP phones in software upgrades. Using methods such as pushing firmware or relying on DHCP information are less common or may require additional configuration and are not the standard practice for straightforward firmware upgrades on Avaya IP devices. Additionally, SFTP, while secure, is not the primary means utilized by Avaya for system updates in this context.
