PAP2 Factory Reset
WARNING! If you're using an unlocked PAP2 previously supplied by Vonage, your adapter will revert back to the settings from the factory after resetting and will immediately attempt to 'phone home', re-provisioning itself from Vonage! If you'd like to reset your PAP2 then re-unlock it, make sure that you disconnect it from the Internet prior to performing a factory reset!
Resetting your PAP2 to its factory default settings (often referred to as a 'hard reset') is done via the built-in IVR (Interactive Voice Response) menu. To access the IVR, simply pick up a telephone that is connected to the PAP2 and dial:
* * * *
(yep, 4 stars) This will activate the IVR 'Configuration Menu' (you'll hear a voice tell you this) after which point, simply press the following sequence of keys to 'factory reset' your PAP2:
7 3 7 3 8 #
Funny enough, the above key sequence spells 'R E S E T', followed by a #. You'll be asked to confirm your selection - simply press 1 to continue. That's it.
