SIP response messages have the wrong IP address in the FROM header when using NAT64.
The SIP ALG with SNAT system will be unable to establish a call for the client.
If the client's IPv6 address does not match the virtual server's configured IPv6 prefix, the FROM header on a response message will have a different IP address that the request message.
There is no workaround at this time.
The FROM header will now contain the client's IP address.
