Do we provide enough access to rehydrate the application upon the case 
where messages were indeed missed?

If a new channel starts the application do we currently reject that, or 
do we accept it? If we accept it how does the newly 
reconnected/connected application know that channel is in it?

I think ultimately best practices and documentation about how to deal 
with this are equally as important as further information.

Pondering a bit I can see applications wanting Asterisk to handle this 
in different ways:

1. Tell me that I'm taking over an application that is still active
2. In case of disconnection buffer the last N messages and provide them 
to me in order when I reconnect
3. Disconnect all channels upon application disconnection and don't 
accept new ones

Thoughts?
