use mediaproxy-2.1.0.

the following is come from mediaproxy-2.1.0 Readme:

Closing expired calls
---------------------
Starting with version 2.1.0, MediaProxy supports closing calls for which all
the media streams did timeout, but for which no BYE was received to close
the
call in the standard way.
This feature will only work, when the OpenSIPS mediaproxy module uses the
engage_media_proxy() command to start MediaProxy for a given call. In this
case the mediaproxy module uses the dialog module to keep track of the call
and can pass the dialog id to the media dispatcher. When a media session is
expired because all streams did timeout, but no closing request was received
from the proxy, the media dispatcher will use the dialog id that was
received
from the mediaproxy module, to issue a dlg_end_dlg request into the
OpenSIPS'
MI interface, instructing OpenSIPS to generate the BYEs for the call,
closing
it in a clean way and generating the accounting records.
To use this, the mi_datagram module must be loaded and configured to use a
UNIX filesystem socket which must also be configured into the OpenSIPS
section
of the MediaProxy configuration as socket_path.
This feature is not available when using the
use_media_proxy/end_media_session
functions in the proxy configuration, because in that case there is no dialo
