Firmware upgrades are announced by e-mail and may be downloaded to your system by using the following procedure. 11.1. New Firmware Release Basically the new release will contain two firmware files, which are downloadable into DPH80 systems using the tftp server. • v1.tfp • v2.
11.3. Downloading • When you receive a new release verify the files as mentioned previously in Section 2. Release. For changing the file names refer to the same section. • Choose one of three options: 1. Run the tftp server in the PC where firmware files are available. 2. Keep the firmware files in the same directory as the tftp server running directory. 3. Set the firmware directory path in the tftp server.
12. Configuration Upload and Download This document aims at helping the user to upload and download configuration parameters from DPH80 system. 12.1. Configuration Upload This feature of DPH80 uploads current system configuration and stores it in a configured PC. This feature is implemented using the standard tftp application. 12.1.1. Upload configuration The DPH80 system must be configured with the system IP address of the upload destination and the filename in which parameters will be stored.
12.2.1. Download configuration The DPH80 system must be configured with the system IP address and filename of the new configuration parameters. This can be done using the web interface, by logging in to DPH80/General Configuration/TFTP Configuration. The download file must be in a specific format understandable by the DPH80 system, and it is very strongly recommended that this procedure be used to modify configurations.
13. SIP and H.323 Phone Book The Phone book feature of the DPH80 emulates the point-to-point functionality of the VOIP protocols. 13.1. SIP phone book Using the SIP phone book feature the user can make and receive calls to other SIP clients without the SIP server (redirect server or proxy server). This feature does not require the phone to be registered to the SIP server. For making peer-to-peer calls, the IP address of SIP proxy server should be set to 0.0.0.0.
Using the phone book feature, the user can make and receive calls to and from other H.323 endpoints without the H.323 gatekeeper or soft switch. Registration with the H323 server (Gatekeeper or soft switch) is not required to enable the phone book feature. For making peer-to-peer calls, the Gatekeeper registration should be set to disabled mode. For this configuration Login to DPH80/H.323 Configuration/Gatekeeper registration.
