RE: CCM with NAT

Hi.

This won't work no matter what kind of traffic you are trying to send from A
to B, this has nothing to do with VoIP or the UC server.

In order to get this working you need to do a 2-way NAT.

Subject: CCM with NAT

Hey GS,

I have question how I can handle the VoIP with NAT like the topology below.
A and B are registered to the same CCM.
When A calls B, A can't reach B, because A has no knowledge of B's Network

Does CCM have any feature which could fix this case?

                                                          Phone B
                                                          (IP Phone) (
172.16.0.10/24)

|
Phone A |
(IP Phone)----------------| Firewal(NAT)l |---------|-------CCM
(192.168.0.10/24)

BR,
