juniper SSG20 firewall has video conferencing issue

I have a New Livesize VC unit behind a Juniper FW on a DMZ directly attached (VC to FW) On FW I have Comcast Business Internet on a port that is configured with MIP that maps one static to the DMZ subnet and VC address. However, When I run a VC call the calls randomly drop when calling an identical VC unit. or any VC unit. Call could last 5 min, 1 min, 20 min etc.. The rules on the FW allow only access to SIP, H323 and Ports needed for Lifesize.
I need to ID if the issue is with the FW or the Carrier. I've attached the config for review on the FW.
Could some sort of packet inspection or FW overload cause the session to just Drop?
If the quality of the connection degrades either latency or band-with, the call should degrade, not just drop. It seems as if either the carrier or the FW is killing the session once established. Any ideas would be appreciated.

usually when I have issues with VOIP and video conf traffic, I make sure SIP ALG is disabled and the outbound policy for my voice traffic has source based NAT enabled.
