* The latest modified mISDN v1.1.x based version is available at:
* http://svn.digium.com/svn/thirdparty/mISDN/trunk
* http://svn.digium.com/svn/thirdparty/mISDNuser/trunk

/*
* XXX The mISDN channel driver needs its native bridge code
* converted to the new bridge technology scheme. The
* chan_dahdi native bridge code can be used as an example. It
* is unlikely that this will ever get done. Support for this
* channel driver is dwindling because the supported version of
* mISDN does not support newer kernels.
*
* Without native bridge support, the following config file
* parameters have no effect: bridging.
*
* The existing native bridge code is marked with the
* mISDN_NATIVE_BRIDGING conditional.
