I have 12 T1's going into 3 servers, 4 in each into "Digium, Inc. Wildcard TE410P Quad-Span togglable E1/T1/J1 card 3.3v (rev 02)" cards. Each "group" of T1's have the primary D on 24 and the secondary D on 96. The first server (ts20) and the last server (ts22) can playback "demo-congrats" fine. The "middle" server (ts21) cannot -- just dead air. If I call via ZAP, dead air. If I call via IAX, I hear the file. I copied /etc/zaptel.conf, /etc/asterisk/*, /var/lib/asterisk/sounds/demo-congrats.gsm from ts20 to ts21 -- no joy. I have seen this in my system log file: Oct 2 18:41:49 WARNING[7477]: chan_zap.c:8087 zt_pri_error: [Span 0 D-Channel 0] PRI: !! Got reject for frame 95, but we have nothing -- resetting! I'm running asterisk-1.2.24, asterisk-addons-1.2.7, libpri-1.2.5, zaptel-1.2.20.1. "show channel zap/?," "zap show channel ?" appear identical between working and non-working systems both "on-hook" and "off-hook." Any clues or clues where to start looking?

Sometimes (let's face it, alot of times, the provider messes something up). Also check that all of your T1 cables are plugged into the correct T1 port. I have made that mistake myself when doing 28 T1s off a T3. I got dead air just as you described. Thanks, Steve Totaro
