Hello, When either I receive a phone call on my TDM400 card, everything I say is echoed back to me, very loudly, with significant delay. This doesn't seem to match the usual echo problems though, as like I said the echo is only heard locally, not remotely. It seems to be with different callers too, so it seems unlikely the echo is coming from the caller. Telephone calls that don't use the TDM400 card don't have this issue. Any ideas? -- Brian May <brian@microcomaustralia.com.au>
