[GoogleCodeExporter]

What steps will reproduce the problem?
1. establish 1-way video call from iPhone 4/3GS(using 3G network) to iPad 
(using wifi network)
2. After the call established (audio works fine), pushed "send video" button on 
iPhone 4/3GS(video capture on iPhone works fine). iPad cannot receive the video 
stream sent from the iPhone, but can receive incoming audio.

What is the expected output? What do you see instead?
Expected output:
iPad can see the video stream sent from the iPhone.

Actual output
iPad can NOT see the video stream sent from the iPhone, but can receive audio 
from the iPhone only

What version of the product are you using? On what operating system?
iOS version: 
iPad 4.2 GM (using wifi network)
iPhone 4/3GS, 4.1 (using 3G network)

Please provide any additional information below.
If I change the iPhone to use wifi network, it works great. iPad can receive 
incoming video sent from the iphone

I have sent the network trace via email, thanks.

Also, I did more tests for the ipad, and concluded that iPad cannot receive in 
coming video stream from the other end as long as they are not in the same LAN. 

Test cases:
1. tethering iPad (wifi-only version) thru my android (on 3G); iphone used its 
own 3G. iPad could not receive video from iphone
2. tethering both iPad (via wifi) and iPhone (via wifi) thru my android (on 
3G); ipad could receive video from iphone 

Thanks,
KC
