[cisco-voip] NAT for Call Managers

[john_burk at oxy.com]

NAT can cause havoc with the RTP stream, but with the right firewall and design/config it can be made to work. I use VPN if at all possible to avoid these issues.

Subject: [cisco-voip] NAT for Call Managers

Is it recommended to use NAT on VoIP. I have two separate cluster one for cisco call manager and other for Avaya. We are integrating both the setups(h323). Is it okay to use NAT. Can someone provide me a document which helps in this reference.


For what reason people do not recommend it in the network, or is it the same that you do not register your call managers with the domain server. Look forward to hear.
