Hi,

after also having asked here some days ago without an answer,
I assume, there is currently no way.

Thus, I started to study a little bit the source code.
Maybe I found a solution, which will work.

I haven't yet understood the whole souce, so I don't know,
whether my solution was silly or not or whether my solution
is reliable or not.

For me it is working great, but use with care!


Roger.



My proposal for a fax-send-success-feedback:

1. Look in txfax.c (approx line 60) for the function
    static void phase_e_handler(t30_state_t *s ....

2. Add some code, which writes the number of successfully sent pages to
    an channel variable:

static void phase_e_handler(t30_state_t *s, void *user_data, int result)
{
    struct ast_channel *chan;
    char far_ident[21];
    char minibuf[11];               <<<< new line

    chan = (struct ast_channel *) user_data;
    if (result)
    {
      fax_get_far_ident(s, far_ident);
      pbx_builtin_setvar_helper(chan, "REMOTESTATIONID", far_ident);
      sprintf(minibuf, "%d", s->t4.pages_transferred);     <<<<<< new
      pbx_builtin_setvar_helper(chan, "FAX_PAGES_TRANSFERRED", minibuf);
                                                           <<<<<< new


Then you'll find the variable ${FAX_PAGES_TRANSFERRED} accessible from
the dialplan.
If you know the number of pages to be sent, you can compare and see if
complete.
