SBC upgrade no Button visible

[GMick]

into admin dashboard i can see that sbc on raspberry 3 must be upgrade but if i go in sbc trunk i not find the upgrade button.
maybe is not compatible with raspberry3? if yes i must change sbc hardware or can i continue to use the same no upgraded?

On the SIP trunk page, check the box by your SBC, then at the top of the page click the Update button on the far right of the row of buttons.
