I was evaluating a condition where a TDM card (TE405 rev1) would not send ANY audio frames whilst transmitting DTMF. It should have been returning muted (silent) audio frames but had *no* data for the driver while the driver was sending DTMF. I have it in as bug 4226 for those interested. > I'm in the middle of documenting specifically the transmission loss > associated with the TDM vs Sangoma card.

I was not experimenting with *any* gains at all during this testing, but it's been almost a year since I was playing with it. -A. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
