You only pasted the answer to the REGISTER request, but this is what I
suppose happened: as I understand, blink is running on a rfc1918
address. However, in the REGISTER response, your contact contains an
internet routable IP address, which suggests someone along the way
changed it. When receiving an INVITE, the request URI will contain your
registered contact address. However, blink remembers registering
something of the form <username>@<rfc1918 address>, but it gets
<username>@<public IP address>, which it doesn't recognise, thus exits.
If this is indeed the problem, we will come up with a solution.
