[Freeswitch-dev] DTMF duration unit

Hi all, I don't clearly get what unit we should use in dtmf-duration parameters (core min-dtmf-duration / max-dtmf-duration and sofia dtmf-duration). The variable name and some parts of the code/wiki imply it's in milliseconds (for example in sofia.c, we can see a line saying profile->dtmf_duration = 100;). However, the default values in switch_types.h suggest the values should be based on timestamp like in RTP. Something like: minimum = 400 @ 8kHz => 50ms default = 2000 @ 8kHz => 250ms maximum = 192000 @ 8kHz => 24s If the later is the right one, should I change values when using WB codecs that are NOT sampling at 8kHz? Also, is the "unit" consistent across all endpoint modules? Thanks, François.
