Conference calling from the computer should utilize the calling method chosen for the computer

When placing a new conference call from the computer it always uses the computer's microphone and speaker. It should utilize whatever calling method is chosen for the extension's settings (RingOut, RingOut to a specific device, etc.)... or it ought to at least give the option to choose the calling device on the "Conference Call" start screen.

Not all of our employees have microphones/speakers on their computers, so starting the conference call using the computer as the endpoint is useless for them.
