Dear Team, I am implementing b2bua server with pjsip version 2.9 I am trying the transfer feature in server. So I want to delay the ack message untill i get the offer. I have implemented the on_send_ack method of inv_session to send ack message manually from application But after sending the ack from the application, if i try reinvite on the session. It is giving error as the invite session state is still in CONNECTING state. Please suggest how can I achieve this functionality Regards, Ajaresh Gudipati.

Hi, I only succeeded by modifying the pjsip source file sip_inv.c (remove /static/ keyword from /void inv_set_state() /and declare /void inv_set_state()/ in sip_inv.h header). After that it is possible to manually change session state after sending ack: { pjsip_event e; PJSIP_EVENT_INIT_TX_MSG(e, tdata); inv_set_state(inv, PJSIP_INV_STATE_CONFIRMED, &e); } Regards, Gabriel.

Hi, I tried to put that code inside pjsip_inv_send_msg() when method.id is ACK. So that no changes are required in api. Is it okay to implement this way.? Regards, Ajaresh Gudipati.

 Hi,

 I only succeeded by modifying the pjsip source file sip_inv.c
 (remove /static/ keyword from /void inv_set_state() /and declare
 /void inv_set_state()/ in sip_inv.h header).
 After that it is possible to manually change session state after
 sending ack:
 {
 pjsip_event e;
 PJSIP_EVENT_INIT_TX_MSG(e, tdata);
 inv_set_state(inv, PJSIP_INV_STATE_CONFIRMED, &e);
 }

 Regards,
 Gabriel.

 Dear Team,

 I am implementing b2bua server with pjsip version 2.9

 I am trying the transfer feature in server. So I want to delay
 the ack message untill i get the offer.

 I have implemented the on_send_ack method of inv_session to send
 ack message manually from application

 But after sending the ack from the application, if i try reinvite
 on the session. It is giving error as the invite session state is
 still in CONNECTING state.

 Please suggest how can I achieve this functionality

 Ajaresh Gudipati.

Hi, Yes, it would be ok if this code is added in sip_inv.c (it's the solution I'm using now): /*  * Send a request or response message.  */ PJ_DEF(pj_status_t) pjsip_inv_send_msg( pjsip_inv_session *inv,                                         pjsip_tx_data *tdata) { ........... if (tdata->msg->line.req.method.id == PJSIP_ACK_METHOD)         {             pjsip_event ack_e;             PJSIP_EVENT_INIT_TX_MSG(ack_e, tdata);             /* Set state to CONFIRMED (if we're not in CONFIRMED yet).              * But don't set it to CONFIRMED if we're already DISCONNECTED              * (this may have been a late 200/OK response.              */             if (inv->state < PJSIP_INV_STATE_CONFIRMED) {                 inv_set_state(inv, PJSIP_INV_STATE_CONFIRMED, &ack_e);             }         } .................
