No official activities there, though people ask about this every now
and then.

This is far from easy a task. First, you need a SIP stack, which is
quite complex a beast (but you can find some good GPL/LGPL ones as

Then you need to rewrite the RTP stack, or rewrite the live555
bindings, to do *symmetric* RTP. VLC only support asymmetric
RTP currently, since it only cares about streaming, not VoIP.

Finally, you need to create a UI, as a media player UI is not quite
usable for VoIP.
