Cisco VTA Advantage and Norton 2010

[fbarquero.fusionet]

Hi all,

Does everyone know why Cisco VTA Advantage does not work when Norton 2010 is installed?. When I uninstall Norton, video works perfectly but our customer wants CUVA and Norton working at the same time. Any workaround?.

CUVA requires the CDP driver which binds to the network interface to work. It will exchange CDP messages with the Cisco phone for discovery. If Norton prevents this, or interferes with the subsequent CAST (TCP 4224) and RTP (UDP 16384-36768) traffic, CUVA will fail. Try disabling any firewall/traffic inspection to see if the issue is resolved. If it does you will need to allow the ports in Norton.

Thanks for the reply. CUVA is properly discovering the phone. The problem is with the video playback. When I uninstalled Norton, the video works properly. Ive run out of ideas to make video work.

Hi,

Probably the Norton AV has port blocking, make sure the video port is not blocked.

Refer to:

"Cisco Unified Video Advantage uses port 5445 by default. If your firewall blocks
this port, users will receive no video. You will need to configure your firewall
to allow access to port 5445 (or change the UDP port setting during deployment and
installation) and enable video.

Thanks for the reply. Im checking that at this mommnet. In order to make a loopback video check, which ports need to be open?.

[Jonathan Schulenberg]

You need to allow the RTP port (16384-32768) ports as well. The PC sends/receives the video media directly; it is not sent through the phone.

After reinstalling Norton and opening the necessary ports, VTA Advantage worked.
