The FTP server backs up individual 4600 Series IP Telephone user data such as screen settings and speed dial data. The data is stored in “data” directory by default:
For Linux: /opt/ecs/mvuser/MV_IPTel/data/FTPdata
For Windows: c:/Program Files/Avaya/MV_IPTel/data/FTPdata
Configuring 4600 Series IP Telephones for FTP backup/restore operation requires providing the FTP server IP address and optionally, a directory path, either in the settings file or by user input. Also, for additional security, the user must input a user name and a password. The Avaya IP Telephone File Server Application reduces the administration requirement to supplying the FTP address only, which should be downloaded from the settings file. Instead of requiring individual directories, user names and passwords, the FTP server interrogates the telephone during a backup or restore for its extension number using SNMP. The obvious prerequisite is that the user has logged in using their IP telephone credentials, which is mandatory to access these functions.
NOTE: To simplify administration, only the FTP server address needs to be specified in the IP telephone settings file.
NOTE: Remember to program the IP Telephone File Server Application server address as a valid SNMP query source in the 46xxsettings.txt file.
The user data is stored and restored by combination of phone extension and phone type retrieved in the SNMP query. Consequently, users can store personal settings and retrieve them in a hot-desking environment, since the data is associated with their personal extension number and not the physical phone instrument.
The Avaya IP Telephone File Server Application mode of operation provides additional security, since only an IP telephone responding correctly to the SNMP challenge during the storage process can either store or retrieve files. This allows the use of simple anonymous FTP logins, for example, not setting user name/password in each phone, to vastly simplify user administration.
The FTP server also has a Super User mode to allow storage of application files. Access is limited only to the IP Telephone File Server Application subdirectories. This provides an alternative method of storing files on the server.
Avaya recommends using a specialist FTP client program such as Cute FTP or WS_FTP to access the IP Telephone File Server Application FTP server. The more explicit messages provided regarding log in and change of working directory status provide better user feedback than trying to use FTP mode in something like Windows File Explorer. Use of Explorer is currently supported for the Windows server version only.
The servers have comprehensive logging capabilities for tracing problems and can be remotely interrogated for status using a built-in HTTP status server.
NOTE: Remember to program the 46xxsettings.txt file to allow SNMP query access to the phone from the File Server Application server. The IP Telephone File Server Application invokes NetSNMP on Linux to retrieve this data from the telephone.
