@mjg59 Roger, some years ago: "your list of codecs is _what_? Oh boy you really are a telephony product aren't you."
@RogerBW I'm sure I can just shove some 16 bit PCM in there, right?
@mjg59 @RogerBW umm. Iirc , which I may not - one of the g7xy suite is 8khz 8-bit, mono PCM . Which is all the quality analogue phones claimed anyway. ( And I suspect how we got to 64kbps isdn )
