sx20 router nat configuration

Is there a cisco validated config for exposing a SX20 unit on a router?  I have a 2911 router.

I don't have a firewall at the site.

I know I can nat the device and enable the following incoming ports the on public ip

udp 1719

tcp 1720

tcp 5555 6555

tcp 11000 20999

udp 2326 - 2845

Do i need to enable any inspect rules for outgoing traffic from the unit?

I know on the sx20 unit, i would have to set the NAT to auto and the call mode direct.

If you do a search for SX20 Standalone in these forums, you will find much information on the ports and requirements for using a SX20 behind a router.

For all video conferencing purposes, and H.323 and SIP packet inspection/fixup should be disabled on your router.

Hi,

Have you made this work?

Can you share the configuration of your router.

Thanks
