The wiki states in the Intro: The old mod_fax, mod_t38gateway, and many of the codecs in FreeSWITCH (mod_voipcodecs) have now merged to one module called mod_spandsp which takes advantage of all the DSP features found in the spandsp library including T.38 endpoint and gateway functionality. Yet the "Installation and configuration" states: mod_spandsp is compiled by default with the freeswitch source tree but is still in testing stage to use it just unload mod_voipcodecs and mod_spandsp and load mod_fax remember to change it in modules.conf.xml mod_spandsp require libtiff. Is that an error, should I fix this? If the old mod_fax, mod_t38gateway and ... modules have been renamed and mod_spandsp is in modules.conf.xml there is nothing to do then? Thanks, jlc
