T48G stops working after firmware update
Phone originally running 35.73.0.50.rom

Prior to upgrade, multiple extensions to multiple asterisk servers working (this is a test phone)... connection is via router based site-to-site OpenVPN connection.

Upgraded to 35.80.0.70
After upgrade, no lines are registering. "unknown uri scheme".

Any idea why it would work before the update and then not work after?
