I'm looking for a client (for mac) that will help me make calls through a connected iPhone. Anything?
Sure. You could try BluePhoneElite 2.
From the authors site:
- Use your computer's microphone and speakers like a Bluetooth hands-free device!
- Phone to computer call-log synchronization
- Incoming call notification with caller ID and customizable alerts
- On-screen call controls and duration tracking
- Search and export call details with notes
and much more...
