[h323plus] how to switch a point-to-point conference to multi-party conference

[Marcos Fábio Jardini]

There are no formal rules or recomendations on how to hot-change an in
course conference. The implementators are free to do what they think that
are the necessary for that. For the purpose of compatibility with end points
of other vendors, the simplest way is to close all connections and
re-negotiate the capabilities.
