Hello.
I wrote a patch (attached) that makes dummy telephony interface send a
DBus signal (through org.bluez.TelephonyTest interface) every time a
voice dialing is started. It may be useful when you have only this
button on a handset (e.g. SonyEricsson HBH602 owned by me) and want to
answer some VoIP client call with it.
Patch works both with BlueZ 4.60 and 4.57-1 built with dpkg-buildpackage.
I have an example Skype client that answers calls using this feature and
Skype DBus API, and can post it if someone is interested in.
