I'm going for v.90 over VoIP over DSL. Hopefully I'll be able to get
a 28.8k connection over my DSL line ;)

It's astonishingly unreliable, although it could be my setup. V.32 is
marginally more reliable than V.90. Yes, I'm using the G.711a codec.

GSM mobile phone making CSD calls to an 0870 number, which comes over
my ADSL via IAX, an into an ATA where I've plugged in an analogue
modem, which is plugged into my router.

Said router speaks PPP and sends packets back out over the ADSL. The
idea is that I can get data using my "free" minutes and avoid Orange's
extortionate GPRS charges. So I have IP-over-V.32-over-voice-over-IP.
Well, until I get a large enough latency spike that the modems lose
carrier and it's game over.

I've not yet tried to do VoIPoV.90oVoIP yet :)
