Hello Shurato!

Thanks for tracking down the block - good call on rgtel and the
127.0.0.1 in its blacklist. I will dial in again now it is cleared.

Short version: don't change a thing for V.8. Diamond Dave reaching
you at 31200 settles it - 31200 is V.34, and V.34 only starts after
V.8 completes. So your side negotiates V.8 fine; the trouble is not
on your end.

The 14400 was mine. My Courier does 31200/V.34 to boards in Europe,
so it is not V.8-shy either - it just cannot complete V.8 across my
route to you: Warsaw -> a cloud VoIP trunk -> PSTN -> your line, and
that long hop adds enough delay and jitter that the V.8 tone phase
falls apart before V.34 can lock. On a cleaner path, like Diamond
Dave's, it just works. Nothing to fix on your side, no init string
needed.

I will run a fresh batch now the block is gone and post the
diagnostics - public link, no login, as before. Mostly an experiment
my end: a Courier on pure VoIP, not a metre of copper.

Best regards,
kombos
