[asterisk-users] Problem in making outbound calls in PRI

[Danny]

Hey everyone !


I have a problem in making outbound calls in PRI connection.
I have E1 PRI airtel connection [ India ]
[ asterisk-1.2.12.1 on CentOS 4.4 ]


zaptel.conf
----------
[channels]
language=en

usecallerid = yes
hidecallerid = no
callwaiting=yes
threewaycalling = yes
usecallingpres=yes
transfer = yes
echocancel = yes
echotraining = yes
immediate = no


;group=0
;context = from-pstn
;signalling = fxs_ks
;channel => 1

callwaitingcallerid=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
answeronpolarityswitch=yes
rxgain=0.0
txgain=0.0

; faxdetect=incoming


;-----
immediate=no
overlapdial=yes
pridialplan=national
prilocaldialplan=national

group=0
context = from-pstn
callerid=asreceived
switchtype = euroisdn
signalling = pri_cpe
channel => 1-15,17-31
; 
------------------------------------------------------------------------------- 



; zaptel.conf
span=1,1,0,ccs,hdb3
bchan=1-15
dchan=16
bchan=17-31


#fxsks=1

# Global data

loadzone        = us
defaultzone     = us

; 
------------------------------------------------------------------------------- 




When i try to make an outbound call, I get this in the error message : -
>>
  -- Executing Dial("SIP/1001-0879af90", "ZAP/g0/908239793") in new stack
  -- Requested transfer capability: 0x00 - SPEECH
  -- Called g0/9821795097
  -- Zap/1-1 is proceeding passing it to SIP/1001-0879af90
  -- Channel 0/1, span 1 got hangup request
  -- Hungup 'Zap/1-1'
== Everyone is busy/congested at this time (1:0/0/1)

I am not sure of what is wrong with my zaptel config. Any suggestions ?
