[asterisk-users] Asterisk + TC400B - Clock Trouble

[lftsy at leurent.eu]

Hello all, I have a TC400B Digium card in order to deal with transcoding and
I have some trouble using it, I have a timer synchronisation problem!
I would be very grateful if you have any idea to help me?
 
It seems that the card is not correctly synchronised to the system because
when I speak to one side, the sound takes 5 seconds to go to the other side,
and increasing, after 30 seconds of call, it takes 25 seconds for the voice
to go to the other end...
 
I have Asterisk 1.4.25.1, Dahdi 2.2.0-rc5 on a CentOS-5.3 (x86_64) server
with a  2.6.18-128.1.10.el5 linux kernel
 
 
Ast CLI when calling with g729
ast-01*CLI> transcoder show
1/1 encoders/decoders of 92 channels are in use.
 
Dahdi start returns:
(SCREEN):root at ast-01:[~]# /etc/init.d/dahdi start
Loading DAHDI hardware modules:
  wctc4xxp:                                                [  OK  ]
 
No hardware timing source found in /proc/dahdi, loading dahdi_dummy
Running dahdi_cfg:                                         [  OK  ]
