[Asterisk-Users] Bridging two FXO cards (X101P) problem

[Francois BERGERET]

Hi the list  :-)

Wondering why I can't "bridge" two X101P FXO cards to forward an external 
call from a first X101P to another analog telephone outside my house 
throught a seconf X101P.

[VACATION]

exten => s,3,Voicemail(u1001)
exten => s,4,Hangup
exten => s,104,Voicemail(b1001)
exten => s,105,Hangup

I temps to do that to avoid missing calls during my summer vacations.
Numbering is ok when receiving a call, but no sound is heard or only few 
peak distorsions in background if I speak loud in the phone.
Normal calls are running well, I use this Asterisk box every day and this 
FXO cards are ok.
What have I missed ?
Thanks for any help.

Best Regards,
