Hi There,

I bought a single T22P for private use and there shouldn't be any upstream provider. It is the first phone of this kind, so I have no experience with it.

First thing I noticed was that the default admin/admin access did not work.
I did a reset (OK for 10 sec.) with connected LAN cable and it still did not work.

I figured it must connect to a provisioning server so I left the LAN cable unplugged. This resolved the issue and I could login with the default admin/admin.

However, when I changed the IP from DHCP to static, the admin password changed again and I had to do the Reset. Maybe it refreshes the provisioning from a server again...

To get rid of external changes to the system, how can I disable the auto provisioning (I couldn't find such an option in the web admin interface) or is there another way to handle this?

The firmware is 7.70.23.10 and the hardware version is 5.0.0.61 .

Thanks for any help.

I think your distributor make some changes in your settings. Do you buy the phone along with account?
Please ask your distributor or sellers for help.
Or you can upgrade to other firmware and test again.
