The new 1600 series phones are a value version of the 9600 series phones. The phones are different from the 4600 based phones that have been used in the past. The first difference is that the phones use the SSON (Site Specific Option Number) 272 in DHCP to set the options for the phone. The second difference deals with how the phone firmware is updated.
Traditionally phones contacted a server via TFTP to download firmware and settings files. The 1600 and 9600 series phones use HTTP. This offers several advantages and makes administration a bit more main stream. Here are a few options for the HTTP server required for these phones.
HTTP to TFTP Relay via IP Office Control Unit – This method uses a procedure within the IP Office to convert HTTP request to a TFTP server and transport the files. In order to set up this method, the phones File Server address will be the LAN interface IP Address of the IP Office. In the System form of the configuration, the System tab has 3 settings that must be configured.
- TFTP IP Address must be set to either a valid TFTP server, or to the LAN1 IP Address if the internal Compact Flash card is to be used.
- The HTTP IP Address in this scenario would be the LAN1 IP address of the IP Office.
- The File Writer IP Address must be set to 255.255.255.255 in order for the function to work correctly.
The process interprets the GET request from HTTP to a GET request to the TFTP IP Address. This method does not support the back up of speed dials as other methods. This method is also limited to 5 sessions. File storage can be on any embedded CF card and does not have to be a Embedded Voicemail Card. The card should be a quality Industrial Compact Flash card. Some files must be renamed in order to properly work with this method. See the Tech Bulletin 99 for details.
HTTP Server via IIS – This method is easy to setup where a Windows server is available. Server 2003 and Server 2008 have IIS as a standard option. XP and Vista both have the Personal Web Server, a trimmed down version of IIS, as an option. Add the web server under Control Panel -> Add Remove Programs -> Add Remove Windows components (or Add Server Role is on a Server platform). Then simply point the root of the web server to the Manager directory. See Microsoft for more information.
HTTP Server via HFS – HFS is a simple to use portable web server that does not require installation or a complex configuration. This method seems to be the simplest due to the ease of use of HFS. Simply download the archive, unzip, and run the executable. Add the files in the manager folder to the shared files, and the setup is complete. See HFS web site for more information.
Both HTTP methods allow for the phone to back up settings and speed dials to the web server.Learn more about this topic at catalysttelecom.com >
