You should not fix the contact for REGISTER messages. The whole system
not only works just fine without it, it is required by the RFC that
the contact is not modified.
I can't recall right now why it behaves like you describe, but I'd
venture to guess that since you fixed the contact and it was saved
with a public IP, the keepalive system ignores it, considering that it
doesn't need keepalives anymore.
