I could do this myself, but I'm still gun shy from having the original HT286 upgraded and then downgraded and then upgrading and downgrading on the HT502.
On my own SPA2102, I always upgraded it myself whenever new firmware appeared.
The PAP2T up was never suggested to me and I'm always reluctant to fool with a product that's not mine. Tweaking is one thing, but firmware is another.
Thanks for mentioning this. I will ask, although I can't imagine a box running any more reliably than this one....for me.
