Yes, OBi numbers being sent correctly **9 300 348 *** fails with 900, whereas **9 222 222 222 works just fine.
The 202 can reach both remotes on wired as well, so this is clearly something funky with the 1032. I've just factory reset it and pedantically followed the steps in the 'official' post, still the same ... **9 222 222 222 works, I can reach the 202 OBiTALK number, but neither of the remotes (an admittedly ageing 100 and a 110).
Utterly stumped, and very frustrated. This setup has worked, untouched, for years, nothing whatsoever has changed that I know of. Your help is appreciated.
