Can you be more specific than “can’t get them to work” What is showing up on the display of the phones?
Are you connecting them to the same 7100?
If different what is firmware of the 7100 you are connecting to? Also what phone firmware do you have on the 7100.
How did you do a factory reset? Via the menu or key sequence?
1.) VVX 400
3.) Same as last NV7100 R10.9.4.E
Phone Model VVX 400 Part Number 3111-46157-002 Rev:A MAC Address 00:04:F2:6B:35:0A IP Address 10.40.0.115 UC Software Version 18.104.22.16830 BootROM Software Version 5.1.4.084
5.) Key pad on phone
If you see VVX 400 on the phone then that means that it can’t connect to the 7100 or the user 2000 has been deleted. Verify that user 2000 still exists on this different 7100 and password is 1234
Are you plugging the phone directly into the 7100 or through a switch?
Try these steps
1. Run debug ip ftp-server on telnet to 7100
2. Plug phone directly into 7100
3. When booting, when you see the cancel button on screen press it,
4. When you see count down, hold down 1-3-5 on keypad
5. When asking for phone passcode, enter 4,5,6
Reply back with debug and what the screen shows.
