I have a grandstream GXV3240. Unfortunately the admin password has been lost. However I don’t have any factory reset options in the menu. If I hold buttons 1 and 9 on start up to factory reset it asks for a password which I don’t know.

I think settings P88, P2, P1 have been changed to lock down the phone.

How can I perform a reset?


If you are able to use provisioning, you can provision a new Password.
