Hi Tobias,

This should be fixed in which I posted this afternoon.

Here's what's going on. The API Phone Amego was using for Bluetooth audio is going away in 10.9 (Mavericks) so I've been testing the new API (IOBluetoothHandsFreeDevice). You can actually select between the two API's explicitly by removing your device in Phone Amego and then adding it back as type "Bluetooth -> Alternate HFP".

The new API requires 10.7 or later so there is the possibility to test it with the current installed base to shake out as many issues as possible and report them to Apple while they are actively working on Mavericks. With, I restored the old API as the default. The good news is this should work much better in Mavericks possibly including echo cancellation.

For those of you actively using the Bluetooth Speakerphone feature, here are some suggestions:
(1) Chose your preferred audio input explicitly under the More tab.
(2) Adjust the audio input level in Sound Preferences if needed.
(3) You can turn off "Echo Suppression" under the More tab.
(4) To minimize echo and generally improve call audio, avoid using the built-in microphone. Using headphones or an external mic makes big difference.
