> Say we have created an AoR, and then had a REGISTER request arrive that mapped to that AoR's endpoint. This will create a non-persistent contact object in Sorcery, which by default is stored in the AstDB. If the AoR is subsequently destroyed via ARI (using {{DELETE /asterisk/config/dynamic}}), the non-persistent contact is not removed. Persistent contacts, on the other hand, are removed as a result of being stored in the AoR's {{persistent_contacts}} container.
> At first, this is relatively harmless, other than continuing qualify spam occurring for the now defunct contact. However, if we re-create the same AoR, the contact in the AstDB is treated as if it were a persistent contact (as it looks like one when the object set apply handler is called). This creates a weird situation where two things will occur:
> (a) Asterisk will fail to raise all of the necessary state changed events, as it will believe that the contact already existed.
> (b) The AoR will end up with two contacts, even if {{max_contacts=1}}: the original dynamic contact, and the fake pseudo-persistent contact it accidentally created from the dynamic contact.
> The proper thing to do is to destroy all contacts when an AoR is deleted via sorcery.
