Avaya 4600 Series manual Telephone and Tftp Server

Overview of Voice over IP (VoIP)

Step 3: Telephone and TFTP Server

The telephone queries the TFTP server, which transmits a script file to the telephone. This script file, at a minimum, tells the telephone which application file the telephone should be using (the application file is the software that has the telephony functionality, and can be easily updated for future enhancements).

The telephone uses the script file to determine if it has the proper application file. A newly-installed telephone will have no application file, and hence does not have the proper one. A previously- installed telephone may or may not have the proper application file. In any event, if the telephone determines it does not have the application file the script file says the telephone should have, the telephone requests a download of the proper application file from the TFTP server. The TFTP server then downloads the file and conducts some checks to ensure the file was downloaded properly. If the telephone determines it already has the proper file, it proceeds to the next step without downloading the application file again.

Step 4: Telephone and the DEFINITY® /MultiVantageTM

Call Server

In this step, the telephone and the PBX exchange a series of messages which cause the display on the telephone to prompt the user. For a new installation, the user must enter the telephone’s extension and the call server password. For a restart of an existing installation, this information is already stored on the telephone, but the user must confirm the information. In either case, manual intervention is required. The telephone and the switch exchange more messaging, with the expected result that the telephone is appropriately registered on the switch.

More details about the installation process are available in the 4600 Series IP Telephone Installation Manual and in Chapter 3 of this document.
