Hello,
when I start pulseaudio I get this error:

> org.freedesktop.DBus.Error.UnknownMethod: Method "Register" with 
> signature "oay" on interface "org.ofono.HandsfreeAudioManager" doesn't 
> exist

I'm running ofono 1.17 and pulseaudio 8.0.
Please, would you help me to understand if the problem is related to the 
compilation of ofono or to the dbus policies?

I attach the dbus conf files.

My system is a custom buildroot environment on RPi3 with kernel 4.4.8-v7
Thanks!
Marco
