I am sorry to see that your e-mail is confidential.  If it were not, I  
would have responded to tell you that there is already an api command  
to send chat messages in a protocol agnostic way (see http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_chat) 
.  In the future if you can send non-confidential emails to the list  
it will greatly assist us in being able to respond to your questions.
