If you happen to know what the profile rule was populated with, the unit would resync to the config server at the scheduled time. If that's the case, you can change the config file in the config server and put a blank password for admin password. Otherwise, your basically stuck without that admin password.
I have same problem. I have SPA962 locked with admin password. I also do not have any config for this phone nor admin password.
I work with Cisco 79xx phones and on those phones there is option to do factory reset by pressing key sequence. Is there any option like this on SPA series? Maybe any hidden button under the cover? Or any option to push new unlocked firmware to phone?
Yes, you're right. If the device was properly secured and you don't have its password, it'll make a great paperweight. :-)
Seriously though, our products are designed to be secure. However, in the event it was not properly secured, you can try the following:
Build a private network with a DHCP server, a TFTP server, and a network sniffer such as Wireshark.
Configure your DHCP server to offer OPTION 66
Power up the phone and look carefully for what the phone requests from the TFTP server Hint: look to see if the phone thinks it's on a specific domain
If the phone thinks it's on a domain, build a DNS environment named for the domain
Power cycle the phone, if your DNS environment is correct, you should now see the file name that the phone is requesting
Build a simple configuration file named for the file that the phone is requesting. Be sure to include an empty password, enable web server, set web server to a known port, and enable web admin access in this file
Power cycle the phone, the phone should request the file, load the new configuration, and wipe out the password
Open a browser and verify that you can access http://PhoneIP/admin/advanced If you can, you can redeploy your paperweight as a phone. If not, may I suggest you upgrade to a SPA525G2 with MP3 player, Bluetooth, and WiFi :-)
