[asterisk-users] DAHDI - PSTN line always busy

[Vito Corleoni]

Hello

 

I have a TDM410 card (3FXO+1FXS), the card is installed, but it's not
working, whenever I start DAHDI the PSTN line always stay BUSY, and the card
light is Blue on all of the 4 ports, and any one call the number will get
the busy tone.

 

If I stop DAHDI the PSTN line become available and my friend can call but
asterisk will not answer because DAHDI is stopped.

 

I thought the problem is in the signaling that I am using for the FXO port,
I've tried fxs_ks, fxs_ls & fxs_gs none of them solved my problem.

 

Here is my configuration if anyone can help (note I am in Saudi Arabia not
usa).
