How to reset the password on a NetComm V100 VoIP ATA:
- in an antistatic workplace, remove the front rubber feet, remove the two screws, separate the bottom from the top by 5mm, then exert about 300g of backward pressure on the bottom; it will separate from clips at the back,
- remove the PCB and place on workbench, locate the four serial port header pins, between the two largest chips, (or imagine a line drawn from the ethernet socket to the WAN LED; the header is half way along that line),
- attach a 3.3V USB serial adaptor to the header pins, pin 2 is ground, pin 1 is transmit data from the ATA, the pin adjacent to pin 1 is receive data to the ATA, and the pin adjacent to pin 2 is a 3.3V supply from the ATA,
- configure a terminal program for 115200 baud, and power up the ATA, lots of text will appear,
- wait for the User name prompt, then hit enter twice, and a [root @ home]$ prompt will appear, like this:
User name: MAX_VOICE_CHANNELS:3
Password: [root @ home]$
- type auth to enter the user configuration mode,
[root @ home]$ auth
[root @ auth]$
- add a new user, in the example below the user is qz
[root @ auth]$ adduser qz -o -services cli -permissions admin
Enter password: qz
User Name Succefully Added.
[root @ auth]$ listusers
1 root HTTP CLI FTP - ADMIN
2 qz CLI - ADMIN
[root @ auth]$ exit
- save settings to flash
[root @ home]$ save
save: codectype = 0, dsp = 0
COUNTRY is 6
**********[Current Flash used is 5739bytes(MAX is 16384bytes)]**********
Configuration saved successfully
- power cycle the ATA, then try to telnet to it with the new username, and explore the configuration options.
