Polycom VSX 6000 and PIX 506

I am having trouble seting up a Polycom VSX 6000 behind a PIX 506e. Polycom documentation and support said that the fixup for protocol h323 must be removed, then all IP opened for the video device IP (on the inside), and then create access-list for outbound traffic to allow:
-TCP 1720
- TCP 3230-3235
- TCP 3603
- TCP 389
- UDP 3230-3253
- UDP 1718-1719

After setting all that, I am able to call, but there is no video nor sound on my station, although the other party sees and hears me.

I added the following lines:
no fixup protocol h323 h225 1720
then added to the access-list for the inside:
access-list 102 permit ip host 10.157.14.40 any
then to the outside:
access-list 104 permit tcp (or UDP)  host a.b.c.d (outside IP nated to the inside) eq port.. any
Then a static NAT for the camera IP.

From what you've said above, it looks like you are allowing everthing in both directions. If this is the case then it should work.

However, given they can see you but you can't see them, it will be either the static nat or the outside access list at fault. Could you post he config for these, obviously changing any real IP addresses?

The problem lies in the fact that the Camera does not detect the connecting IP, it gets the IP that calling camera is giving.
This is why we couldn't call a number on the internet and in the same time calling an IP on our leased line VPN, the camera is either sending the real IP (internet call is ok), or sending its virtual IP (VPN call is ok).
We solved the situation by making a change in our network thus allwoing the traffic from VPN to reach the real IP of the camera.
