This does not help. If you have one in hand an Post pictures of MOBO to find out If it has a jtag port for example, then we may be able to see if there any posibilities of being able to jtag this Unit.

VD22 should be the same as VD21 which I add support a few years ago. Check this

I have been struggling to open the vonage box due to non-availability of proper tools.I am currently looking for security bits tamper-proof screw driver.
People who already opened the box might help me by posting a picture of the screw driver here and it would be great if you can let me know where can i get one in usa.

Use a small flat screw driver and insert in then you can open it. No need to use the special tool. If you do not have the right width tool, use a bigger one and file it to make it fit.

Finally i could open the box as suggested by Admin.

I think as usbbdm said both vdv21 and vdv22 are same except for the display part.

Take a close look of those missing risistors.

Yes there are missing resistors. So can you tell me how to hook up a serial port so that i can change the sip settings?

[jtagntvdv22]

Can you let me know if the red box i marked on the pic is the place we need to connect serial port,if yes can you let me know which of them are gnd,tx,rx and power.

That would be for Serial TTL Tool And with a Meter you can Measure out VCC(+) ang Ground. A bottom View of Board will let you see which pin is Ground... Then you can connect the tx and rx and check if it works, If not Switch the TX and Rx wires. It is Fairly Easy to figure Out.....

You might need to JTAG to erase Vonage settings.
For serial port there is only 4 pins. One is GND and one is VCC, I always use try and error and should not take long to find the pins.

[jtagntvdv22]

is there any other way to change sip settings using serial port and without using jtag.
