[h323plus] h323plus text messaging

Hello,

I'm working on a conference project,and we will use the H.323 protocol to establish a connection between monitors, so they can exchange information about configuration options of the video stream they'll receive.

So, once a call is established, in addition of exchanging video and audio (that we already have implemented apart), configuration options need to be sent in text format back and forth.

Searching through h323plus I couldn't find a way to send text in a call, can you give me some pointers on how to accomplish that?

Thanks, Nahra.
