[Linphone-users]from tag in BYE

[Kedar B. Patil]

Hi,

I receive and incoming invite, when I store the OsipDialog in a global
variable dialog and then accept the invite as:

static int
invite_cb (OsipDialog *cl, transaction_t *trn, sip_t *sipmsg, void*p)
{
    dialog = cl;

    osip_dialog_accept_invite(cl,trn);
    printf("\n= CONNECTED = \n");
    return(0);
}

=======================================================================

Then I use the same OsipDialog later to send BYE for the same INVITE session:

osip_dialog_bye(dialog);

However, from tag in BYE, is not same as To-tag in 200 OK that was
sent to INVITE. So I get 481 response.

I was wondering if I am missing anything.

Any help in this appreciated.
