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 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.
