If anyone has any assistance that would be great .

Thanks

“application/scaip+xml” is not a supported content type. Code and support would have to be written for such a thing. According to the output, that has not been done so the MESSAGE request wasn’t handled.

And based on the other post I just noticed/remembered, you’ve altered the code.

The MESSAGE request is trying to go into the dialplan at extension “ta74”. You do not have dialplan for that. Your dialplan is expecting a number at the front.

Hi There,

Thank you for the quick reply.

I had a 415 error on the content-type and i modified the res_pjsip_messaging.c file and made a new standard object which resolved that piece.

static enum pjsip_status_code check_content_type(const pjsip_rx_data *rdata)
{
        int res;  
        if (rdata->msg_info.msg->body && rdata->msg_info.msg->body->len) {
                res = ast_sip_is_content_type(
                        &rdata->msg_info.msg->body->content_type, "text", "plain") ||
                      ast_sip_is_content_type(
                        &rdata->msg_info.msg->body->content_type, "application", "scaip+xml");
        } else {
                res = rdata->msg_info.ctype &&
                        (ast_sip_is_content_type(
                                &rdata->msg_info.ctype->media, "text", "plain") ||
                        ast_sip_is_content_type(
                                &rdata->msg_info.ctype->media, "application", "scaip+xml"));
        }

        return res ? PJSIP_SC_OK : PJSIP_SC_UNSUPPORTED_MEDIA_TYPE;
}

Are you saying then further is required ? I was thinking the payload body from the sip message would be parsed using a handler next.

your reply was too quick sorry i didnt see it before you posted !

exten => .,1,NoOp

I take it you mean something alone these lines ? this would make sense i will test later .

Thanks
