Yes, you can post hangup processing. See the wiki channel_variables page and
look at "api_hangup_hook" for more information. Just know that it can get
tricky to try and post-process calls from right inside the dialplan. In most
cases we recommend using the event socket and having absolute control over
the call, including what happens at hangup. Lua is especially good at this.
