Parameter P232 and P233 are for Prefix and Postfix for Firmware, respectively.
Parameter P234 and P235 are for Prefix and Postfix for Configuration File, respectively.
Firmware Prefix and Postfix allows device to download the firmware name with the matching
Prefix and Postfix.
In addition, when Parameter P238 (Check New Firmware only when F/W pre/suffix changes) is
set to 1, the device will only issue the Firmware Upgrade request if there are changes in the
firmware Prefix or Postfix.
Following are the firmware
BASIC NAMES
related to BT100: “boot.bin”, “bt-110.bin”,
“html110.bin”, “vocbt.bin”, “vp.bin”.
Service provider can use “gs_” as prefix, and “_1.0.7.5” as postfix, the above files will be
changed
to: “gs_boot.bin_1.0.7.5”,
“gs_bt-110.bin_1.0.7.5”,
“gs_html110.bin_1.0.7.5”,
“gs_vocbt.bin_1.0.7.5”, “gs_vp.bin_1.0.7.5”
The purpose for this is that now, ALL of the firmware with different version can be stored in one
single directory, and they can be differentiated by using prefix or postfix, i.e., all files with a
postfix of “_1.0.7.5” belong to the firmware version 1.0.7.5.
Same rule applies to configuration files, i.e., for configuration file named “cfg000b82000001”,
there can be 3 versions: “gs_cfg000b82000001_cfg001”, “gs_cfg000b82000001_cfg002”, and
“gs_cfg000b82000001_cfg003”. Here, the
BASIC NAME
of the configuration file is
“cfg000b82000001”, but there are 3 different versions, the one that will be accepted is the one
with matching prefix and postfix specified in the current configuration.

In addition to the Prefix and Postfix for firmware and configuration files, different server paths
for firmware upgrade or Configuration File Server can be specified in different FQDN, i.e.:
Firmware Server Path:
firmw are.grandstream.com/HT502/1.0.7.6
Config Server Path:
provisioning.grandstream.com/HT502
The parameters are P192 and P237 for Firmware and Config Server respectively.

When parameter P194 (Auto Upgrade) is set to 1, Service Provider can use P193 (Auto Check
Interval) 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
