...ible - how is it that a
single ISDN conversation only uses 64K for bidirectional communication
(using ulaw, correct?), but on several occasions now have seen
references to ulaw voip conversations using 64K per side of the
conversation, plus packet overhead
(http://www.zytrax.com/tech/protocols/voip_rates.htm - seems to be down
now - plus other references) for a total of over 128K per ulaw 'full
duplex' voice conversation?
Thanks
