hi to all,
I've been playing around asterisk in about one & half week, now I've configured the Zap channel (FXO)
All the configuration files are working correctly but still my asterisk server is unable to answer the incoming call.
Here are all my configurations files, I hope this would help

;configuring FXO channel

/etc/zaptel.conf/
loadzone=us
defaultzone=us
fxsks=1

/etc/asterisk/zapata.conf
[channels]
usecallerid=yes
hidecallerid=no
callwaiting=no
threewaycalling=yes
transfer=yes
echocancel=yes
echotraining=yes
context=incoming ; Incoming calls go to [incoming] in extensions.conf
signalling=fxs_ks ; Use FXS signalling for an FXO channel
channel=>1 ; PSTN attached to port 1

;Here is very basic dialplan
/etc/asterisk/extensions.conf/
[incoming]
exten=>s,1,Answer()
exten=>s,2,Echo()

The output of 'ztcfg -vv' tool is as below
Zaptel Configuration
======================
Channel map:
Channel 01: FXS Kewlstart (Default) (Slaves: 01)
1 channels configured.

The Zttool has verify the hardware status

OK Wildcard X101P Board 1

I've plugged the PSTN line into my FXO port but when I dail my number from external phone, it bypass my Asterisk server, and Asterisk is unable to respond.
Any Help in this regard is highly appreciated.

I think there might be some error in card. Also change signalling type to fxsls or fxsgs and check.

Well the zttool gives out status ok, if I change the configuration than its gives out unconfigured message. This means the card is doing well except it dont give out Alaram but the status is ok there in

Check out the alarm. When u plug PSTN line in the FXO jack.. the alarm must signalled green. If it is not.. then I m sure the card is defective.
