Greetings, I am running Asterisk 1.4.25 with Dahdi Complete 2.2.0, on a Digium TE121B PCI express card with a VPMADT032 echo cancellation module, connected to an AT&T 24 channel PRI. When I run dahdi show channel X on an active channel, I see this: Echo Cancellation: 128 taps unless TDM bridged, currently ONSo I know the echo cancellation is working, however when I call a local analog land line, I get discernible echo. Here is my chan_dahdi.conf: [channels] ; configuration for T1 card as PRI language = en group = 1 echocancel = yes echotraining = yes signalling = pri_cpe switchtype = 4ess usecallerid = yes context = incoming channel => 1-23 Someone has to have had some experience with these hardware echo cancellers, any ideas? Should I adjust my rx and tx gains? Any advice would be very helpful. Thank you. --
