Hi Ed

This is from a system with a Sangoma A200 on a Virgin/Telewest analogue 
line, haven't had a problem in 2 years

/etc/wanpipe/wanpipe1.conf

[devices]
wanpipe1 = WAN_AFT_ANALOG, Comment

[interfaces]
w1g1 = wanpipe1, , TDM_VOICE, Comment

[wanpipe1]
CARD_TYPE 	= AFT
S514CPU 	= A
CommPort 	= PRI
AUTO_PCISLOT 	= NO
PCISLOT 	= 11
PCIBUS  	= 0
FE_MEDIA	= FXO/FXS
TDMV_LAW	= MULAW
TDMV_OPERMODE	= FCC
RM_NETWORK_SYNC = NO
MTU 		= 1500
UDPPORT 	= 9000
TTL		= 255
IGNORE_FRONT_END = NO
TDMV_SPAN	= 1

[w1g1]
ACTIVE_CH	= ALL
TDMV_ECHO_OFF	= NO
TDMV_HWEC	= NO

/etc/zaptel.conf

loadzone=us
defaultzone=us

#Sangoma A200 [slot:11 bus:0 span:1]
fxsks=3
fxsks=4

/etc/asterisk/zapata.conf

[trunkgroups]

[channels]
context=default
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
relaxdtmf=yes
rxgain=4.0
txgain=2.0
group=1
callgroup=1
pickupgroup=1

immediate=no

;Sangoma A200 [slot:11 bus:0 span:1]
context=from-zaptel
group=0
signalling = fxs_ks
channel => 3

#context=from-zaptel
#group=0
#signalling = fxs_ks
#channel => 4

As you can see only channel 3 is in use and yes I know zaptel.conf says 
loadzone=us defaultzone=us but it appeasr to make no difference with 
this card.

Hope this helps
