I'm trying to provision a new VVX 250, but I can't find the setting. After rebooting the phone, hitting cancel, entering the admin code 456, there is no setup menu option. There is a Factory Reset option, SPT On/Off option, and Exit Option. Also, in the settings menu of the phone, there is no Advanced area that has the provisioning settings there.
I also checked the Web Interface and couldn't find the proper setting. The phone came with UCS version 6.3.1.0.
The phone company I use thought maybe the firmware was the problem, since they are still using version 5.8.2.4732, but we weren't able to downgrade the firmware either.
Any ideas?
