Thanks for the info!

B will also need to send calls to A on a different port... so I guess I'll need to create an additional profile so FS will listen on an additional port?

Security isn't needed in this case.

And this will act as an SBC right? None of the IPv6 addresses from A will show up in SIP traffic going to B? (and vice versa)

So you just want to receive calls from A (which is a well-known IPv6 address) and send them to B.

I would then modify the internal profile to be the exact same than external, except that I would bind internal to 2001::2:5060 and external to 1.1.1.1:5060.
Then you just need a basic dialplan (public.xml) to send to B calls received from A.
Of course, some security would be also a plus.

Hello all,

I'm looking to implement the following scenario:

Step 1
SIP Server A sends INVITE to port 5060 over IPv6 to FreeSwitch:
2001::1 --udp/tcp--> 2001::2:5060

Step 2
FreeSwitch SIP NATs the INVITE and sends it out IPv4 to SIP Server B on port 6000
1.1.1.1 --udp/tcp--> 1.1.1.2:6000

Step 3
All SIP Server B responses within this SIP dialog are sent back to SIP Server A along the same path.

REGISTER messages WILL NOT be processed by FreeSwitch. They are handle elsewhere.

There is more to this but I want to accomplish this first call flow go from there.

Is this possible with FreeSwitch? Can someone point me toward a resource on how to get this created?

The following looks like a good start but it seems it's setup for users to register. I would prefer not to have this.


Thanks!
Joe
