I would like to dynamically manage the "DTMF Mode" during a call, by controlling the options described here: https://freeswitch.org/confluence/display/FREESWITCH/DTMF As follows.... DTMF behavior for a single audio path can be captured by a triple of booleans as follows: Mode Suppress Detect Regenerate passthrough . . . passthrough . X . Intercept X . . Intercept X X . Intercept X X X This looks ideal for my scenario as I need to use different settings for each channel on the call, and will also need to change the settings "on the fly". Can anyone please tell me how/where I can set/change the different options? FYI: I need to support inband and rfc2833 as I have no control over what providers will send). Many thanks. Andy
