Unable to Do Outbound using SIP Trunk

Hi there,

Need Help

Following are my Server details

  1. Asterisk 1.4.42
  2. SIP Trunk
    3.Cent OS

I have configured SIPTrunk in sip.conf file. I am able to receive calls but i am unable to do the outbound using that particular SIPtrunk.

If i do configure the same details in xlite soft phone , i am able to do outbound.

My Configuration Details :

sip.conf

register => UID:PWD@Server IP/UID

[SIPtrunk]
type=peer
username=XXXXXXX
secret=XXXXXX
fromuser=XXXXXX
host=XXX.XXX.XXX.XXX
dtmfmode=rfc2833
canreinvite=no
insecure=very
qualify=yes
nat=no
fromdomain=XXX.XXX.XXX.XXX
context=language

[100]
disallow=all
allow=gsm
allow=ulaw
allow=alaw
type=friend
username=100
secret=test
host=dynamic
context=myphones
qualify=1000
mailbox=100

extensions.conf

[myphones]

exten => _X.,1,Dial(SIP/SIPtrunk/${EXTEN},60)
exten => _X.,n,Hangup()

When i try to call outbound i am getting following error in my asterisk console

Received response: “Forbidden” from ‘“100” sip:UID@xxx.xx.xxx.xxx;tag=as728b65f0’
– SIP/SIPtrunk-0000008e is circuit-busy
== Everyone is busy/congested at this time (1:0/1/0)

Please help me out

Thanks in Advance

Please issue the “sip sep debug on” command and copy/paste the output when you do a call via the SIP Trunk.
