Help: I can't make external calls using AsteriskNOW (xlite, voipbuster)

Hello, I have downloaded the free PBX software called AsteriskNOW (2.0.2). And I am using the SIP softphone Xlite (5). And using Voipbuster.

I have made an internal call between two Pc’s. But now I want to make external calls to for example a mobile cellphone or a fixed phone. But my problem is that I can’t make any external call. Port 5060 is open. I have made a trunk and an outbound line.

And my question is now how do I need to set up the settings to make external calls.

This is what I have in the trunk set up:
Peer details:
type=peer
context=from-voipbuster
host=voipbuster.com
username=eCommercePartner
secret=*********
fromuser=eCommercePartner
fromdomain=voipbuster.com
insecure=very
disallow=all
allow=alaw

And I have registered the trunk: eCommercePartner:********* @sip1.voipbuster.com

And this is what I have in the outbound route set up:

I have a X. in the dial match pattern. And configured with the Voipbbuster trunk (trunk name).

Thanks.

Dump Asterisk now and install a real FreePBX Distro from this site.
