Multimedia option to be added to Csipsimple

Components

CSipSimple - High quality OpenSource SIP for messaging and calling.

Proposal

I would like the Multimedia option to be added to the Csipsimple open source Application.

Mockups / Examples

The default Messaging application on Tecno Camon CX air would be used to illustrate this.
Below is a screenshot of how the multimedia option looks like on the default Messaging application on Tecno Camon CX air.

I would want it to be added at this section on the Csipsimple.

Benefits

This will allow users to share multimedia easily such as video, audio, etc. Adding feature to Csipsimple will attract more users to it.
