Bridging Modules

Beginning in Asterisk 1.6.2, Asterisk introduced a new method for bridging calls together. It relies on various bridging modules to control how the media streams should be mixed for the participants on a call. The new bridging methods are designed to be more flexible and more efficient than earlier methods.

Bridging modules have file names that look like bridge_xxxxx.so, such as bridge_simple.so and bridge_multiplexed.so.
