I have recently bought a SPA504G phone and set it up successfully for a single SIP extension. I'm using the 7.6.2f firmware which is the latest at time of posting. All works fine until a power outage and when the phone restarts it reverts to an outbound proxy of nat.gradwell.net:5082 in the EXT 1 tab of the SIP extension setup.
Every time I re-update the setting, I click on the "Submit All Changes" button and on restart all works as it should.
What am I missing, can anyone help?
