Instant messaging from xlite to xlite through asterisk

[quote]i get an error message “method not allowed” + “other member using earlier version” and dropped message on asterisk cli at the same time ,im using asterisk 1.4 on fedora 6 and xlite 3.0
what to do ? [/quote]

Asterisk only supports IM in established voice or video calls.

I still get this error message while i attempt to send instant message to other xlite phone, during established call, error is as under:
(Notice: The person you are sending messages to is using an earlier version of X-Lite, which does not support rich text and emoticons. You may have to send some of your messages again.
Error: Method Not Allowed)
