Hello
I have everything working in a2billing but I can't get it to connect the call

I added the configuration to the sip.conf then I tried calling a U.S. number and a2billing said its unavailable, not sure why tho , I was wondering if any one could see the problem.
My sip.conf looks like this right now:
This part is the setup for my incoming DID
[general]
register => arya6000:password:arya6000@vbuzzer.com:80/14162738101
[vbuzzer]
type=friend
user=arya6000
host=vbuzzer.com
port=80
fromdomain=vbuzzer.com
fromuser=arya6000
secret=password
username=arya6000
insecure=very
context=a2billing ; Or whichever context you would like incoming calls to be placed to.
authname=arya6000
dtmf=rfc2833
dtmfmode=rfc2833
canreinvite=no
nat=yes ; Even if not behind a nat, use nat=yes
useragent=vbuzzer/1.0
disallow=all
allow=gsm
allow=ulaw
allow=alaw
qualify=200
and this part is the setup for my trunk
[5084010000000000]
host=72.5.55.200
disallow=all
allow=ulaw
dtmfmode=auto
type=friend
context=a2billing
username= (arya6000@******.trial)
secret= (mypass)
#include additional_a2billing_sip.conf
And in the a2billing admin GUI I setup the trunk by giving it a name and I put the IP address, I put 1 for prefix and for provider tech I put"SIP"
Did I do anything wrong in setting it up?
Thanks in advance
