[OpenSIPS-Users] ERROR:tm:t_forward_nonack: discarding fwd for a cancelled/6xx transaction

[Bogdan-Andrei Iancu]

Hi Krunal,

Looks like a race between the INVITE and CANCEL.....typical way to deal 
with that is by processing the CANCEL only if it matches an INVITE 
transaction:

    # CANCEL processing
    if (is_method("CANCEL"))
    {
        if (t_check_trans())
            t_relay();
        exit;
    }



do you have this in your script ?

Regards,
Bogdan
