Not exactly. Fully duplex audio (AT VTR mode) is available on PCI hardware modems. Specifically the Banska/Netcomm iNTRA released in 1999 (for which drivers are part of standard 2.4 kernel) This comes in a 2, 4 and 8 port version on PCI and comes with an onboard processor. It is capable of running up to 8 cards in a single machine - giving 64 ports in total. It was designed in part for use in IVR systems. If a full-duplex modem channel is not developped soon then it is something I will be doing medium term when we need this in Australia and NZ branch offices.
