Configuring PIX for Skinny and RTP with NAT

[gboulle]

Hello,

On site A, I have IP Phones and CCM 3.3 configured and I would like to add new IP Phones on site B separated from site A by 2 Firewalls (Cisco and Check Point).

What do I need to open on PIX (running 6.3) to allow call establishment between both site ?

Does Cisco PIX support static NAT (or HIDE NAT) with skinny or RTP ?

Can I add QoS support to VoIP with Cisco PUIX ?

Regards,

Guillaume

Hi

Here is a link to a page which describes which tcp or

udp port a cisco callmanger uses. Hopefully this helps you.
