- * 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.
