Pulseaudio (or the meego PA modules for voice) isn't really an option
for at least the following reasons:
- lots of modems still handle all audio and PA will know nothing
about calls at all with these modems
- PA does not really care about individual calls, but whether
the audio traffic channel is connected or not
- multi-call cases, cases were traffic channel is reconnected
mid-call, etc, etc, PA simply does not know enough (and should
not)
I guess this could be done in higher layers on top of oFono (telepathy-ring,
dialer app, policy framework, etc), but I don't really know enough about
the call timer stuff to comment on the pro/cons of this.
