Hi, I'm not entirely sure of why or how, but I've noticed that whenever I'm making and sending a re_INVITE through the sip_inv module and the reply is negative, it takes over 30 seconds to reach the TERMINATED state. For a positive reply it will reach TERMINATED almost instantly. It's bothering me because for inv->inv_tsx to be re-set to NULL, the transaction must be at least in the CONFIRMED state. This means that I cannot send a new re-INVITE for more than 30 seconds. Could someone please shed some light on what is happening here, or at least tell me what I am doing wrong?
