Cluster resource managers (one is included as part of heartbeat) can
certainly perform any check you can write a script for.

I would expect you start Asterisk with a script; e.g.:

  /etc/init.d/asterisk start

That script probably also has a stop and a status action:

  /etc/init.d/asterisk stop
  /etc/init.d/asterisk status

The 'status' action can be used by heartbeat / rgmanager / etc. to check
the health of the asterisk server.
