2. How does template file become configuration file and loaded into Grandstream product?

When Grandstream Terminal Device boot up in the same LAN with GXE5000(LAN Port), it will go

through following process:

 Issue DHCP Request, acquire both IP address and the TFTP server IP through DHCP Option 66,

here GXE5000 function as DHCP Server.

 Issue TFTP request for configuration file with name “cfg000b82xxxxxx”. Here the TFTP

request contains Grandstream proprietary extensions that contain Grandstream Product model

information, see following example:

Trivial File Transfer Protocol

Opcode: Read Request (1)

Source File: /GXV-3000/cfg000b8209ba7d

Type: octet

Option: blksize = 1024

Option: tsize = 0

Option: timeout = 4

Option: grandstream_MODEL = GXV-3000

Option: grandstream_NAT = 1

Option: grandstream_ID = 000b8209ba7d

Option: grandstream_REV_BOOT = 001.001.003.002

Option: grandstream_REV_PHONE = 001.001.003.014

 When GXE5000 received the TFTP request, it will base on the product model to look up the

template file and generate the device configuration file dynamically.

3. Template file name format.

Product-Model-base-provision, here Product-Model has to be the product model shown in the tftp

option, e.g., GXP-2000 or GXV-3000, their template file will be GXP-2000-base-provision and GXV-

3000-base-provision, respectively.

4. Template file management.

Currently GXE5000 contains following product templates:

Unknown/BT-100/BT-110/BT-200/GXP-2000/GXP-2020/GXV-3000/GXW-4004/GXW-4008/HT-

286/HT-386/HT-487/HT-488/HT-496

Here Unknown is a special template that it will only assign variables to P34/P35/P36/P47, in case a

TFTP request does not contain a known product model or no model option in the TFTP request.
