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?
