  1. How do I start WBD?
  2. WBD is a multicast shared whiteboard. It is best to start it using a session directory tool, like SDR. WBD does not do call or session invitation for two reasons. There are several alternative protocols for performing call setup and negotiation, and adding code encumbers the tool unnecessarily. In addition, these call setup and negotiation is reasonably complex and best handled elsewhere so that audio, whiteboard, etc, can all leverage the same functionality if desired.

    If desired WBD can be launched from the command line as described below.

    You can start it from the command line using an IP address and port number as arguments. The syntax is:

    wbd address/port

    To join a multicast group (address range to just enter the group address and a port number.
