SIP/VoIP being blocked through Forefront TMG

Forefront TMG is blocking all our out going SIP data. Giving this error;

Denied Connection POE 10/17/2013 12:35:56 PM
Log type: Firewall service
Status: The policy rules do not allow the user request.  
Rule: Default rule
Source: Internal (
Destination: External (
Protocol: SIP

I have run the 'Configure VoIP' task and set it to allow RTP, SIP, FTP and NTP(UDP) from my internal VoIP phone ( to the hosted server ( but for some reason that I cant see its getting blocked by the default rule and seems to be missing out the VoIP access rule altogether.

Any help will be welcomed.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Since no one has offered anything I will respond.  I am not familiar with this box, but I have seen many firewall products where the rule was configured for Wan to LAN verses LAN to WAN --  Your 'Configure Voip' tool may be opening / allowing the connection in the wrong direction.

The fault is due to Forefront TMG not being able to publish the protocol to the multiple internal VoIP phones. I can get 1 pone to work but any more and certain features stop working.

I have decided to create a vlan an bypass the TMG for the VOIP system.
