peter,
i didn't find in rfc5626 a requirement that registrar should remove 430
flow contact, but, if there is such a requirement, in my opinion removal
should be done from failure route in the script by a function that
removes the contact.
a similar thing was discussed a while back (see below).

Why only UDP? Are TCP contacts removed when the TCP connections is closed?
IMO there should also be a mechanism to remove ALL expired unresponsive
contacts.
how about the following for tcp contacts:
- set_forward_no_connect();
- if t_relay() fails because tcp connection does not exist,
unregister the AoR/contact
what would be needed is a find out that t_relay() failed due to
non-existing connection and a script function to do un-registration of
an AoR/contact.
perhaps both of these two things already exist?
