Asterisk dont answer call

I just instaled Asterisk. When I call, the ring goes but asterisk is not answering call.

My extensions.conf file is



exten => s,1,Verbose(1|Unrouted call handler)
exten => s,n,Answer()
exten => s,n,Wait(1)
exten => s,n,Playback(tt-weasels)
exten => s,n,Hangup()

exten => s,1,Answer()
exten => s,n,Echo()

exten => 500,1,Verbose(1|Echo test application)
exten => 500,n,Echo()
exten => 500,n,Hangup()

include => internal

while my chan_dahdi.conf file is


; define channels

channel => 1            

channel => 2

The general advice under such circumstances is to consult the commercial support channels for the card vendor. This forum is the wrong place for getting commercial support from Digium.

In any case, you need to identify the actual hardware, provide the contents of the dahdi system configuration file, and provide, as a start, verbose console logging output. You also need to identify the PTT and the exchange line product they are providing, and to make it clear whether it is calls from the PSTN or local phones that are failing.

thaanks David for the reply. You think there is chance it is hardware problem? I am using Digium TDM410 card, 1 FXO and 1 FXS module on it. The FXS port is working fine but FXO is not answering the call. When I attach my phone set to FXO socket, it get calls from PSTN without anyproblem.

Digium provide support with the configuration of their cards, as well as with hardware faults.
