[Asterisk-Users] Xten & Digum TDP FXO card: No sound

[Andrès Tello Abrego]

I have a tdm 3xfxs and 1xfxo, aslo I have a setting with 1 snom 190 and 2 xten 
line. 
 
I can call from the snom to the ptsn line at the fxo port ok.
I can call from the ptsn to the xten lite phone.
I can call from the xten lite to snom 
but 
what I CAN`T do is; 
Call from xten to ptsn. When I dial from the xten, I can hear the dialed 
party, but he cannot hear me... 
 

Tips? Help? 
What I'm doing wrong? 
 
TIA
