                    <ul class="">
                      <li class="">I switched back to old Freeswitch
                        from Feb 2016, as new FS always answered with
                        488 on T.38 reinvite from the B-Leg</li>
                      <li class="">Then I implemented the following
                        (coding outside of FS with XML-Curl)</li>
                      <ul class="">
                        <li class="">When call is done with T.38 on
                          boths legs, do not anything special, just use
                          a minimum dialplan<br class="">
                        </li>
                        <li class="">if B-leg does not answer with T.38,
                          this normally fails in my environment. I then
                          store a Value NOT38 to the dialled number for
                          1/2 hour in a cache<br class="">
                        </li>
                        <ul class="">
                          <li class="">when then the fax machine is
                            retrying the same call, I lookup the cache
                            and return another dialplan with T38 gateway
                            (self) enabled<br class="">
                          </li>
                        </ul>
                      </ul>
                    </ul>
                    <p class="">That way, pure T.38 calls work nicely,
                      and calls with T.39 on the B-leg work on the
                      second try.<br class="">
                    </p>
                    Hope this helps. At last here in Germany, we have to
                    find some workarounds, as fax implementation on some
                    carrier's side (to say the positive) does not

                      and variables (I see e.g.
                      "fax_t38_tx_reinvite_packet_count" in the release

                        this Version of Freeswitch is from 09-Feb-2016.
                        So I think, we should update.<br class="">
                        <br class="">
                        We need to cover 2 scenarios<br class="">
                        <ul class="">
                          <li class="">send fax to SIP Provider(b leg)
                            and have T.38 Re-invite from SIP Provider
                            and pass it to a-leg</li>
                          <li class="">send fax to SIP Provider(b leg),
                            do NOT receive T.38 Re-invite from SIP
                            Provider and then do T.38 Gateway in FS.<br
                              class="">
                          </li>
                        </ul>
                        And no: We cannot foresee, whether the SIp
                        provider will do T.38 and not. Here in Germany,
                        the main incumbant PSTN provider did not
                        implement T.38, so it depends on the target
                        number and actual route, if this will be T.38 or
                        not. A call to a certain number can be T.38
                        today and tomorrow it will be T.30 only, as some
                        peering partner changed the routes in the
                        meantime.<br class="">
