Is it possible to use RLine and/or RCall for the following?
* Put active call on hold.
* Reclaim on hold call (make active).
* Add (join) call to multipart (conference)
* Transfer call.
* Exclude call from multipart (split multipart).
* Reject alerting incoming call.
* Send DTMF tones.

Please post if you know the answer to any of these and preferrable with a note where I can find some more info.
