[Asterisk-Users] Outgoing call on Zap channel always gives DIALSTATUS ANSWER even when BUSY?

[Jeremy Lichfield]

Outgoing call on Zap channel always gives DIALSTATUS ANSWER even when 
BUSY? Has anyone run into this?

Here is my conf files:

Zaptel:
span=823,1,0,d4,ami
e&m=1-24
loadzone = us
defaultzone=us

Zapata:
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1
immediate=no
busydetect=yes
context => incoming
signalling => em
group => 2
channel => 1-24

Extensions:
[default]
exten => 1000,1,Dial(Zap/g2/14356355785,10,tT)
exten => 1000,2,NoOp(Dial Status ${DIALSTATUS})

Sip:

fromuser=XXXXX
secret=XXXXX
host=dynamic
dtmfmode=info
nat=yes
disallow=all
allow=g729

Am I doing something wrong? Or do I need something more?
