+====== Using Asterisk as a Conference Bridge ======
+Using Asterisk as a conference bridge is much simpler than using it as a voicemail system because it does not require you to integrate OpenSER and Asterisk's database tables. No views, no trickery, and no editing the source code.
+==== Programs Needed ====
+  * Latest Asterisk
+  * app_cbmysql for Asterisk
+  * Web MeetMe
+  * Tables for CbMysql
+==== How This Will Work ====
+In OpenSER, add an account for asterisk. Then, set Asterisk up to register to that account. There won't need to be any route modifications because Asterisk will just be another number for users to call. Unfortunately, most of what I found online seemed to be multiple pieces that I just happened to put together.
+==== Configuration ====
+Be sure to fill in all username, password, and other settings with your details.
+=== Asterisk's sip.conf ===
+<code>
+[general]

+Unfortunately, it is pretty hard to determine what is happening with this project. More information about app_cbmysql and the web-meetme gui can be found here:
