[asterisk-users] asterisk and simple chat protocol

[Nhadie]

Hi,

We are trying to use a softphone with instant messaging which uses 
SIMPLE. i tried sending a message to the user, this is what i got:

[Mar  5 22:59:39] WARNING[1884]: chan_sip.c:9825 receive_message: 
Received message to <sip:100 at mydomain.com> from 
<sip:333 at mydomain.com>;tag=1d32305f, dropped it...
   Content-Type:text/plain
   Message: test


anything i need to be able to support SIMPLE?

TIA

regards,
Nhadie
