Asterisk will call this channel driver callback with the two channels that are bridged together. In Asterisk 11, chan_dahdi performs the reads on the DAHDI channels and - when a FD on one channel indicates there is data - directly writes the received data from DAHDI out to the other DAHDI channel with no decoding. Note that in Asterisk 12+, this mechanism changed. Instead of using a channel driver callback, a bridging framework is used. That bridging framework has a pluggable interface, allowing a native bridging technology to be written in a separate module (outside of the channel driver) and selected based on criteria it presents to the core. The DAHDI native bridging is now implemented in the bridge_native_dahdi module.
