[asterisk-users] No audio on Zap (T1/PRI) channels

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?

Thanks in advance,
