This module offers support for instant message conference. It follows the architecture of IRC channels, you can send commands embedded in MESSAGE body, because there are no SIP UA clients which have GUI for IM conferencing.
You have to define an URI corresponding to im conferencing manager, where user can send commands to create a new conference room. Once the conference room is created, users can send commands directly to conferece's URI.
To ease the integration in the configuration file, the interpreter of the IMC commands are embeded in the module, from configuration poin of view, there is only one function which has to be executed for both messages and commands.
The following modules must be loaded before this module:
The following libraries or applications must be installed before running OpenSER with this module loaded:
The database url.
The default value is "mysql://openser:openserrw@localhost/openser".
The name of the table storing IMC rooms.
The default value is "imc_rooms".
The name of the table storing IMC members.
The default value is "imc_members".
The power of 2 to get the size of the hash table used for storing members and rooms.

Handles Message method.It detects if the body of the message is a conference command.If so it executes it, otherwise it sends the message to all the members in the room.

A command is identified by the starting character. A command must be written in one line. By default, the starting character is '#'. You can change it via "imc_cmd_start_char" parameter.
Next picture presents the list of commands and their parameters.

Before running OpenSER with IMC, you have to setup the database tables where the module will store the data. For that, if the tables were not created by the installation script or you choose to install everything by yourself you can use the imc-create.sql SQL script in the database directories in the openser/scripts folder as template. You can also find the complete database documentation on the project webpage, http://www.openser.org/docs/db-tables/openser-db-devel.html.
