Thanks for all your solution,
I tried these all things to managed PRACK after this creation by Invite session.
I think use the solution of the module to do it.
I'm reading again the developpers guide, and I understand more thing that at my first reading.

You *probably* need to invalidate the transmit data so that the message is re-printed to the message buffer. This can be done by using pjsip_tx_data_invalidate_msg(tdata).I don't normally use this callback to modify the message so I'm not sure if this is the case, but you can try it yourself. -benny

Hi, I'm trying to add some header on Transmit Data thanks to the callback call_on_tsx_state_changed from a module session invite, but when I see the trace of my SIP message, there aren't any modification : No Subject Header. static void call_on_tsx_state_changed( pjsip_inv_session *inv, pjsip_transaction *tsx, pjsip_event *e ){ /*pjsip_tx_data *tdata; pjsip_generic_string_hdr *hsubject; pj_str_t name; pj_str_t value; name = pj_str("Subject"); value = pj_str("PJSIP_UA"); puts("Subject"); puts("PJSIP_UA"); if(e->type == PJSIP_EVENT_TX_MSG) { tdata = e->body.tx_msg.tdata; hsubject = pjsip_generic_string_hdr_create(tdata->pool, &name, &value); pjsip_msg_insert_first_hdr(tdata->msg, (pjsip_hdr*) hsubject); }*/}I have tried pjsip_msg_add_hdr too. I use simpleUA example and the following page to do my code.http://trac.pjsip.org/repos/wiki/SIP_Message_Buffer_Event#GettingtheSIPMessagefrompjsip_event May be there is a bug ? Thanks by advance for responses. C?dric.
