There is the IndicateCall D-Bus method in the org.bluez.Headset interface
which you can use (see doc/audio-api.txt for more info). However for
proper telephony integration you'll need to use a telephony driver (see
audio/telephony-*.c) so that the call indication occurs because of a real
call event of your telephony subsystem.

By default bluez compiles in the dummy telephony driver which provides a
simple D-Bus interface to drive it. There's also a python test script for
it in test/test-telephony which you can use to simulate telephony events.
E.g. "test-telephony incoming 1234" would simulate an incoming call from
the number "1234" and should cause the RING to be sent for HSP
connections.

Also note that starting with version 4.33 bluez uses HSP version 1.2 which
does *not* use the RING indication when the AG has been configured to use
inband-ringtone (for out-of-band ringing it's still used). However 4.32
(which you have) still has HSP 1.1 where the RING indication will always
be sent.
