So, this isn't really the topic of conversation in this thread. Most
of this thread concerns itself with discussing additions/modifications
to ARI and its manipulation of bridges.

Keep in mind that the CONFBRIDGE function modifies the ConfBridge
application, not all bridges in Asterisk. Adding capabilities to the
ConfBridge dialplan application won't really affect the topic this
thread is discussing.

The CONFBRIDGE function should *not* be re-purposed for things outside
the ConfBridge application. If someone wanted to write a generic
dialplan function that modified properties of a bridge, that would be
a better solution than using CONFBRIDGE.

That being said, the dialplan is extremely channel focussed. That is
both a strength (it is relatively simple and straight forward) and a
weakness (doing things outside of manipulating a single channel can
become convoluted). I'm not sure that adding these kinds of
capabilities to the dialplan is the best way forward.

That being said, Asterisk is open source. If someone wants to write a
generic bridge function that modifies bridges in Asterisk, that would
be an interesting patch.
