For this problem I really do not know. I think our system does not pay that much attention to the Contact header but simply connects the registered device with the TCP/TLS socket used.
I doubt there is anything missing on the client side if you simply does not receive the INVITE. Are other packets reaching the device? MESSAGE, keep-alive, etc?

We have made some good progress. Below is the current status.
IPV4 - Phone register successfully, both Incoming and outgoing calls are working fine.
IPV6 - Phone register successfully, outgoing calls are working fine but when some one dial the extension of the phone under IPV6, FreeSwitch server doesn't send the INVITE to the phone .
Below is the register packet received on the server. Is there any other change we need to make on the app or Is that a FreeSwitch issue. Contact header have IPV6 address.
