Do you do this just so you don't have to rely on module loading loading the \
bridge technology first?

parking. First I've created a bridging technology that is very minimalistic in \
nature (it doesn't do any actual communication between channels on a given \
holding bridge) for storing parked calls. This technology will also likely be used \
for queues and maybe some other stuff later on. Second, I've created an \
application that holds a reference to a single holding bridge which can place \
channels into the holding bridge. It includes some options for playing music on \
hold, ringing, and for breaking the bridge (such as in a queue/park timeout) after a \
certain amount of time.
