Thanks a lot. Let me a question about "purple_send_mesage" exported function:

if (is_method("MESSAGE")) {
    xlog("MESSAGE $ru from [$fu] to [$tu]\n");
    if (uri !~ "sip:.+ at .+;proto=.+") {
        purple_send_message();
        sl_send_reply("200", "Accepted");
    }
}


Why is needed to reply "200"? doesn't this module act as a proxy
waiting for a response from downstread (i.e. MSN network) and mapping
that response to the appropiate SIP code?

This is: if I send a MESSAGE to a MSN account not online (or not
existing) I will receive "200" anyway, shouldn't I receive a 480 or
404?

Regards.
