Also, from a previous note, you wouldn't want to turn off V.42/V.42bis since that is where the error correction is. Also, even on compressed data, you get some additional bandwidth because it does packetized synchronous data. This gets close to 8bits/byte instead of 10 (start, stop).
I think that you *do* want to turn off V.42. V.42 does error correction by using error detection and retransmission. This introduces variable delay and throughput, which are unacceptable in a real-time application like voice. I think that error correction through error correction codes is the way to go. - -- Miron Cuperman <miron@extropia.wimsey.com> | NeXTmail/Mime ok <miron@cs.sfu.ca> | Public key avail AMIX: MCuperman | cyberspacecomputingcryptoimmortalitynetworkslaissezfaire -----BEGIN PGP SIGNATURE----- Version: 2.1 iQCVAgUBK3i7lZNxvvA36ONDAQF3sQP+Ibesz2FVTGLfWL0Xsjj5X1jFkEU807va +qpmDLDGghgdM5xCpc+Xv8Zl8lJx356WMPrbZfdshumXtmjsqf33Wq6fcAUse87k 6nsPiTkDpWnsga9g6oKUjPjTuQUcdk7VzrosJ+l3MAnvhQ0bD1TJD2ySIQk8NIPV +uGM5Ore+6Q= =7ViZ -----END PGP SIGNATURE----- New signature on my key: -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.1 mQCNAiqvJ10AAAED/jXfntqmsRjJRYoxYTxLO7obzMfzgUNtSDEawb3Suj4UO1xq uARc25PJNAHQhIa83Yxf9z/R/3AjwmYrZqxvB2RkLPTjTmzQd04fypsZToiR/TlM 5F43JCuCM779mAir9Idy1CQzXQ2bn89eUZaVhOUJzNgndl+wLpNxvvA36ONDAAUR tCxJbW1vcnRhbCBGcmVlZG9tIDxtaXJvbkBleHRyb3BpYS53aW1zZXkuY29tPokA lQIFECtQgZGoEwOvWCFMNwEB4ecD+wdqaIGhJgfhlY+ypQwmgN3ytgUi/MjgmUdT B2qfjRj0uhyXOPegSQ+n0ZF4wHEo1a2osdAo387iYHNebqAOv1+3xM10beI/RNT1 dZwUcm/LXwuCRACAqlL5lB5cQNy4ZbG/QvioAWYqqq6g9ftiI6Z1nkvZ6mIb9QZv WBCysIj8iQCVAgUQKxc8tJNxvvA36ONDAQG/bQP+Mgq7zP0M/7BMstZhllrH3Cck nNGQP3/+QUALSKzosw0xJJfTIbA4+aoQjvXQFKi+5MCU0GaoGsyuXQGnluzGkI3w XDcxzR7Hl97V5+hyRWNc0sw/QbimWvQAUwDgpc0T4x/AsUx34Zx3G5+ujTIqgHKC wfBD6ib6u61E8jLz38+JAEUCBRArDHAdS60iYsR4D/cBAZCdAXwPRl2uvP6QwCC4 4A0GFufGbm3NqThNaDfuGn+JTYIR8htb8hRUg8SM2G8zpyNnWNA= =AVXx -----END PGP PUBLIC KEY BLOCK-----
