Hi! I found this thread: http://lists.freeswitch.org/pipermail/freeswitch-users/2013-March/094032.htm... and I have the same problem (all faxes with transfer rate: 14400 are dropped) It seems that nobody ha an answer back then for the question (is there any way of forcing freeswitch to use transfer rate: 9600) The result: 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:512 ============================================================================== 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:524 Fax processing not successful - result (48) Disconnected after permitted retries. 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:529 Remote station id: 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:530 Local station id: <local_number> 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:531 Pages transferred: 0 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:533 Total fax pages: 0 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:534 Image resolution: 0x0 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:535 Transfer Rate: 14400 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:537 ECM status off 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:538 remote country: 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:539 remote vendor: 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:540 remote model: 2014-08-29 15:21:39.187130 [DEBUG] mod_spandsp_fax.c:542 ============================================================================== Thanks in advance!
