If you are using a large number of DAHDI channels, you could designate a chunk of them as "non-local" since you can control RXGAIN on each channel. You would have to work out something with your TELCO since your'e a dead duck control-wise once you answer the call.

I'm having issues at a couple of offices where calls made to local numbers are fine but a when a calls from or goes to a large percentage of long-distance or 1-800 numbers the person at the remote end cannot hear the person in my office. Boosting the gains in zapata.conf (I'm still using 1.4.21) to 8 solves the problem with long-distance lines, but then local calls say the person in my office is too loud. I understand that it is going to be difficult to reliably detect a major drop in the volume at the far end of the call, but I'm just wondering if there is a good solution for this. We're using Rhino WC4-FXO-ec cards and the OSlec echo canceler (since the on-board echo canceler didn't seem to help our echo issues) Thanks, Brent _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
