SIP-T42G 29.83.0.50

The phone is manually provisioned and has been working steadily for a while. Now the phone is rebooting and getting stuck on "Initializing" when PC port is being utilized. Multiple computers checked and the same issue is presenting itself as soon as the port gets connected.

Attempted firmware upgrade but this had no effect on the issue. Enabled network span to PC port but the phone exhibits the same behavior.

Any additional troubleshooting steps that can be recommended? There are no VLANs on the network and VLANs are not enabled on either port in the phone.

Hi there, thank you for your response

The phone works fine without anything connected to the PC port. I am checking on how the user is powering the phone now and will have them try a known working adapter.

Did you ever find a solution to this? We are having the same issue with T29s.
I am having similar issue with T29G also?
