Re: Reinvite after delayed ack

    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 
      

      Regards,
      Ajaresh Gudipati.
