..., a telephony card is not involved. I'm running asterisk-1.2.13 and zaptel-1.2.10 on Linux 2.6.15-27-386 (Ubuntu 6 distribution without X). Hardware includes a P III 600 MHz, 386 MB RAM, an X100P card that's not part of this test (also used an X100P clone card to same result), and a CS4239 sound card (ISA) with ALSA driver (also tried with OSS to similar result but OSS had a harder time getting volume up). ALSA needed a bit of tweak to work properly with CS4239, but afer carefully setting alsamixer, I don't hear much echo when making calls from the console. Yuan Liu
