Mihai and Steve,
As per your previous posts, it seems PortAudio is the main stumbling
block to getting iax lib on the iPhone.
Unfortunately, it seems the Audio Hardware interface is not supported,
which takes a big whack out of pa_mac_core.c
So, e.g. the CoreAudio calls AudioDeviceGetProperty and
AudioDeviceGetPropertyInfo are not implemented.
Any advice as to where I would look to begin to work around this?
