  how can I connect to existing socket?

You can't really but you also shouldn't need to. You can request
bluetoothd to change the volume using the SetProperty("SpeakerGain", 0-15)
method on the org.bluez.Headset interface on the D-Bus object that
represents your headset. There's a python script in the bluez source that
lets you do it too, e.g:

test/test-telephony <remote address> speakergain 10
test/test-telephony <remote address> microphonegain 5
