About four days ago I suddenly could no longer call out via my iTalk trunk. As I have had issues with my FreePBX distro in the past I thought that I might have corrupted something and decided to rebuild. I have just done so with the latest FreePBX (stable) build, using Asterisk 11.4 But alas the same thing is happening.

The iTalk IP trunk and IP trunk registrations are all online. I revieve call in but when I try and call out I get told that all ciruits are busy.

I can call our via my VoipRaider connection. If I set up iTalk up on a standard sip phone I can phone out and recieve calls. It would appear that something has changed on iTalk's side as it used to work just fine but now it simply wont allow me to dial out via my FreePBX distro.

My peer details are as follows:
type=friend
secret=************
username=**********
fromuser=************
host=akl.italk.co.nz
dtmfmode=rfc2833
insecure=port,invite
nat=yes
canreinvite=no
disallow=all
allow=ulaw&alaw
qualify=yes

Any ideas
