iPhone 5 on Sprint network

I tried calling our HDX8000 B using my iPhone with Polcom's PrealPresense software.  The call goes through but nobody can see me.  I see them but video from my phone to the HDX is not visible.  I'm using AT&T U-verse wifi. 


Coworker in other office up north has an iPhone 5 with Verizon and it worked without a problem.  Using Wifi and 4g.


Any ideas what could be different?  I recently downloaded the newest update for Polycom's RealPresenence so I know iPhone 5 is supported now.

Hello kg2140,

welcome to the Polycom Community.

This is most likely caused by a network restriction / firewall within your providers network.
