Video over ip with cisco 891

Hello,

We used to communicate with our office in Vietnam by using a video conference terminal (polycom HDX 7000)

We just used H.323 protocol, without any gatekeeper, and called the other endpoint terminal with just the IP address.

Few days ago, we changed our internet access router with a cisco 891.

It's now impossible to etablish call with our video conference system.

I configured NAT to redirect specific ports, but it still doesn't work.

Maybe there is something special to configure on this router ?

I disabled the firewall, but no change !

Anyone can tell me if there is a service to activate/desactivate, or antything else, to use H.323 protocol this way ?

Thanks a lot

[sorry for my poor english]

What is your previous router?

try to enable disable H.323 nat features with "ip nat service h323 ..." or "no ip nat service ..."

Regards.

Thanks a lot.

I disabled h323 ip nat service with "no ip nat service H323" and then I was able to etablish a call.

But there was still a little problem, I was able to send audio and video but I was unable to received it.

I had to select "NAT is not compatible with H323" on my Polycom terminal.

Now all is OK, thanks.
