asterisk users - Jul 2005 - No sound when bridging two single FXO cards

Wow ! No reply... May be I must talk about X100P instead of X101P ?
Is someone has yet encountered this kind of "no sound" problem when
bridging
two FXO lines like this (first as input, second as output) ?
Any idea ?
TIA.

What you shouldn't do is start a new thread.

It should work, assuming they indeed sit on two different analog lines.

Ok, sorry for this lack of explanations.
I run Asterisk 1.0.7-BRIstuffed-0.2.0-RC7k.

The log has recorded this during the last test of bridging two FXO lines :

"","","s","default","","Zap/2-1","Zap/3-1","Dial","Zap/3/ww0164417888","2005-07-15"
12:34:25","2005-07-15 12:34:25","2005-07-15 
12:35:49",84,84,"ANSWERED","DOCUMENTATION"

The call progress normaly, but no sound.

And, yes, the incoming and outgoing calls are placed normaly with my cards 
(3 cards, in fact).
They are seen as X101P by Linux (at boot).

Zaptel tell that :

Zaptel Configuration
=====================
Channel map:

Channel 01: FXS Kewlstart (Default) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Slaves: 02)
Channel 03: FXS Kewlstart (Default) (Slaves: 03)

3 channels configured.

My zapata.conf :

cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
echotraining=2000
rxgain=4
txgain=4
busydetect=yes
busycount=5
group = 1
context = pstn
signalling = fxs_ks
callerid=asreceived
amaflags = documentation
channel => 1-3

My zaptel.conf :

loadzone=fr
defaultzone=fr
fxsks=1-3

How to trace the bridge establishment from CLI ?
I know how for IAX or SIP protocol, not for zap interface...

TIA
