Making outbound calls

hi ,
could some one pls help me with a little problem i am having .
i just finished configuring , an E1 line , i can succefully receive an incomming call , but i can’t seem to make ian outbound call , the following are my configurations;

on zapata.conf

trunkgroup => 1,16,32
spanmap => 1,1,1
[channels]
usecallerid=yes
hidecallerid=no
callwaiting=no
threewaycalling=no
transfer=yes
echocancel=yes
echotraining=yes
language=en
context=incoming

signalling=pri_cpe
group = 1
channel=>1-8
channel=>9-15

context= outbound
switchtype=euroisdn

signalling=pri_cpe

group = 2
channel => 17-25
channel => 26-31

NOTE: i had to define two seperate context for incoming and outbound call, and split the channels .

ON MY EXTENSIONS.CONF

[globals]
OUTBOUNDTRUNK = Zap/1&Zap/2&Zap/3&Zap/4&Zap/5
TRUNK = Zap/g1

TRUNK=Zap/g2 ; Trunk interface

[incoming]
include => outbound
;exten => 4601700,1,Goto(aheeva_sbr,s,1)
exten=> 4601700,1,Dial(SIP/103)

[outbound]
include => incoming
exten => _X9NXXXXXX,1,Dial(${TRUNK}/${EXTEN})
exten => _X9NXXXXXX,1,Dial(${OUTBOUNDTRUNK}/${EXTEN})

NOTE: i define two trunk groups, so that the dial plan cld pick any one that fits , don’t know if i did the right thing , but i really need some help on this.

the extension i defined on my sip.conf to make and receive the call is given below;

[103]
type=friend
host=dynamic
username=103
secret=103
disallow=all
allow=ulaw

on my zaptel.conf , these are the configurations i have ;

span=1,1,0,ccs,hdb3,crc4
