the call ends when the BYE is coming through, so at that time you can
delete from htable -- if the BYE is missing, then the htable auto-expire
will clean it (like dialog auto-expires will do it for dlg case).
Just as side note, in 3.3.0, dialog module exports events routes
executed when a call is started or ended, so you can do easier
operations related to this events (e.g., no matter dialog is ended by a
bye or timeout, you will get a specific event route executed), see:
