Yes, you cannot use the same (hungup) channel to transform it into an
outbound callback call. You're right about that asterisk creates a new
thread for each channel, AFAIK. So your callback solution cannot be done
with dialplan only. You have to create a script that upon hangup waits
the time you need and then creates a callfile to originate the callback
on its own call. The same script could do the job using the AMI
Originate action. This is sort of a quick answer, because I haven't had
the need to develop a callback solution and I'm pretty sure there's much
better solutions out there with similar concepts.
