[Freeswitch-users] Multiple Tone Detect

[Anthony Minessale]

there is a specific app for fax detecting inside mod spandsp called
spandsp_start_fax_detect


it takes about the same input args namely <app> [<arg>][ <timeout>]
It uses the official fax identification code inside spandsp and works
much better than the single tone detect way.
