> Autocreated peers on the SIP channel never send any PeerStatus events. Discovered while trying to upgrade from 1.8.8.
> The reason is that autocreated peers are, well, autocreated using the temp_peer() function. There is a stanza in register_verify() which currently (13.8) looks like 
> {code}
>     if (!peer && sip_cfg.autocreatepeer != AUTOPEERS_DISABLED) {
>         /* Create peer if we have autocreate mode enabled */
>         peer = temp_peer(name);
>         if (peer) {
> {code}
> Since the transition to Stasis endpoints for reporting, an endpoint is initialized in the function build_peer(), but not in temp_peer(). So the autocreated peers do not have their `sip_peer.endpoint` field set.
> The temp_peer is a horrific misnomer, because those peers are just good normal peers, only autocreated. They are not inferior in any sense. I am mentioning that because next comes the commit 0b83761, AKA SVN changeset r394795, which attempted to fix crashes caused by the unset reporting endpoint--by simply disabling all events from these peers! I would not be surprised if the author was confused by the name of the function and implemented an incorrect fix.
> The feature has been broken since the introduction of Stasis (12.0?).
> Since  temp_peer() has been also recruited to create an authentication "(Bogus peer)" (which I do not fully understand), it is probably more correct to just allocate an endpoint for autocreated peers at the site of the call to temp_peer in the above code snippet. Additionally, rolling back 0b83761 is also an option, as long as it can be proven that the "(Bogus peer)" never causes any Stasis communication.
