asterisk users - Sep 2009 - Asterisk-1.6.2.0-rc1 and Instant Message sending

Hi,
i have try to send IM from Client A (Ekiga) to Client B (Ekiga).

I have enable the textsupport in the sip.conf.

I used this "How to":
http://www.voip-info.org/wiki/view/Asterisk+Documentation+1.6.1+realtimetext.txt

sip.conf
[general]
         [...]
     disallow=all
     allow=ulaw
     allow = alaw
     allow=t140
     allow=t140red
     textsupport = yes
     videosupport = yes
     allow=h263
         [...]

But Asterisk dropped the Message:

[Sep  5 19:57:05] WARNING[17906]: chan_sip.c:13724 receive_message: 
Received message to <sip:2000 at khaolakforum.de> from "Jens

<sip:2001 at khaolakforum.de>;tag=66a2f62e-b398-de11-99d4-00c0268c092d, 
dropped it...
   Content-Type:text/plain;charset=UTF-8
   Message: test

Is this Feature already implemented in Asterisk ?

Realtime text is sent in the RTP stream. What you're sending is a SIP  
message. Those are two different things.

Asterisk does not support SIP messages outside of a call - so test  
while you have a call in UP state.
If you want Asterisk to send IM messages, test the sendtext()  
application in the dialplan.
