asterisk users - Feb 2004 - New Firmware for Grandstream Phones - Supports CFG by MAC address

The newest firmware from grandstream supports configuration by mac address.

Simply upload a file cfg<mac address>.txt

Does anyone know the format of a cfg.txt? ?

i saw something about that on the voip-info wiki

Everyone has been after the format for ages, but so far I don't think 
anyone has it..

Hi list,

I have worked a little on debugging the Grandstream cfg.txt file and here is
what i found out so far:
The binary header is like this:
00 00 01 00 (always the same start) 52 d2 (checksum of 2 bytes) 00 0b 82 00
XX XX (phones mac address in hex) 0d 0a 0d 0a (two carriage return and new
lines)
after this header the config follows in clear text - looks url encoded like
: P2=admin&P8=0... etc. (find the variables in the webconfig of the phone)
the clear text is terminated with a 00 byte
If anyone figures out how to calculate the 2 byte checksum then please tell
me ;-) (this information is from older firmwares - didnt check if they
changed binary header in the newer versions...)

Cheers,
Jens Davidsen
