Grandstream Networks HandyTone-496 Manuel D’Utilisation

34 

 
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File 
through TFTP or HTTP. “Config Server Path” is the TFTP or HTTP server path for configuration file. 
It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can 
be same or different from the “Firmware Server Path”. 
 
A configuration parameter is associated with each particular field in the web configuration page.  A 
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric 
numbers.  i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page.  For a 
detailed parameter list, please refer to the corresponding firmware release configuration template. 
  
When Grandstream Device boots up or reboots, it will issue request for configuration file named 
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., 
“cfg000b820102ab”. The configuration file name should be in lower cases. 

 
 

 
Starting from firmware version 1.0.3.18 for HandyTone-496, adding prefix and postfix for both 
firmware and configuration file is supported. 
 
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix 
and Postfix.  This makes it the possible to store ALL of the firmware with different version in one 
single directory.  Similarly, Config File Prefix and Postfix allows device to download the configuration 
file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be 
stored in one directory. 
 
In addition, when  the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, 
the device will only issue firmware upgrade request if there are changes in  the firmware Prefix or 
Postfix. 
 

 
When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in 
minutes, default and minimum is 60 minutes) to have the devices periodically check with either 
Firmware Server or Config Server, whenever they are defined.  This allows the device periodically 
check if there are any new changes need to be taken on a scheduled time. By defining different 
intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File 
download in minutes to reduce the Firmware or Provisioning Server load at any given time.
