Can't Firmware update with SBC

[Alan H]

With the new v16 update, all of our Yealink's are behind on their firmware. I can't update the software without removing SBC and changing it to Stun just to get the firmware to download and run. Any ideas on how to fix this to where I'm not touching 40 + phone?

I've had an issue with firmware rolling out behind SBC / STUN.

Had to get customer to power cycle (not soft reboot) the phone and it worked fine after that.

Also when you first provisioned the Phones as SBC were they done via PnP from the management console? What is the Firmware they are currently on?

Firmware for the T29G are v46.83.0.55, and I can't remember how I provisioned the phones previously.
