This system can receive IP calls from external systems. But when I dial out to test outgoing calls (IP calls) the other side see's the call come in and receives it but no video/audio on their side. On the calling side I get the following message on the screen "No incoming video" then call terminates. The only messages in the log are below.
Log messages:
WARNING: IPv6 address configuration

Oh yeah, anytime you're dealing with video, any type of firewall inspection should be disabled as it could cause a delay or simply no video being sent/received.

Make sure your System Configuration > H.323 > Profile 1 > CallSetup Mode is set to "Direct" rather than "Gatekeeper". This should allow you to dial directly out without being registered to a H.323 Gatekeeper. You can safely ignore the Default Call Protocol Warning Message when you have it configured this way.
For your IPv6 issue - if you don't use IPv6, turn it off by changing the System Configuration > NetworK > IPStack to "IPv4" rather than "IPv6" or "Dual".

Thanks Wayne,
Callsetup was set to direct. I changed the Stack to IPv4. Can you think of any other reason why out going call would get this message? Like I mentioned before I can receive calls. But dialing out is my problem. I checked with the called party and we are both using H323 at 384Kbs. See call history page from dropped calls. I have attached the call details for the calls that I made. Disconnect cause 16 (Q850) and the other call to a test site 71.14.2.157 0 (Internal)

Note, this is a continuation of this question, configure-cisco-telepresence-sx20-use-h323, it might help get some additional background for you Wayne. Also Jeffery, suggest since you now have the SX20 configured to be a standalone H323 endpoint that you mark any relevant and helpful replies in your other thread as answered, and since you created a new thread to address the video issues you're not getting.
Regarding the "Default Call Protocol", as Wayne suggests, you can ignore that error as that is typically if you're configured it as a standalone endpoint. IPv6 is typical error as well if you're not using that network type, I have that error on all of my endpoints, as we don't use IPv6 and it doesn't affect anything.
You have all the required H323 ports open on your firewall? Take a look at cisco-ex-tandberg-ip-sip-firewall-ports.
Is NAT properly configured on your firewall, as well as the SX20?

My apologies I will do that right now.

Incoming session no problem all ports are open nat correctly configured.

From your screenshots it looks like there is only media flowing in one direction. The cause of that in 99% of cases is firewalls that are not correctly configured to allow the traffic flows on the required ports. Make sure the following are open at both ends:
*Configurable by "RTP Ports Range Start" and "RTP Ports Range Stop"

I will verify these ports. Thanks

Yes all ports are open. The device can receive incoming IP calls with a video/audio session. The problem is outgoing IP calls that's when I get this message.

Problem solved "Turn H323 inspection off" on the firewall.
