Hi there I have a video conference unit (H323) which sits behind a DMZ on a Cisco 1812 router & then static NAT the required VC ports. Outbound calls are established OK but the video conference kit has a brief incoming call message when accepting inbound calls but these do not establish. Is there a required IOS version I need on my Cisco router or any specific H323 commands/services to enable or disable to get this to work? Are there any specific video conference commands to help establish video conference kit to work over and above normal static NAT rules?
