-------------------------------------

    Resolution: Not A Bug

This is not a bug.

Generally endpoints require connection reuse, that is they connect to Asterisk and expect that same TCP connection to be reused. This is accomplished using the "rewrite_contact" option. If this is enabled and Asterisk is restarted it prunes the relevant contacts, as the underlying TCP connection has been lost and a new one can not be established back to the endpoint.

> With regards to persisant sip registrations, only UDP transport works.  TCP doesn't seem to.  What I observe happening is when I shut down asterisk, and start it back up, all TCP sip registrations are removed from the ps_contacts table but UDP registrations remain.  I've confirmed this in the sql logs.  There are indeed delete commands for the TCP registrations.
> So, when asterisk is restarted, UDP endpoints work right away.  TCP endpoints need to wait until they re-register.
