...t the user is pressing on his phone. We have a PRI test circuit and an analyer in between to measure tone duration. We have tried setting chan_dahdi.conf parameter 'toneduration', but that does not do anything that we can measure. We have also tried setting channel.c parameter #define AST_DEFAULT_EMULATE_DTMF_DURATION 200 to several different values but none seem to alter DTMF duration at all. Does anybody have a clue where we can hardcode DTMF duration for tones going out of a DAHDI Channel to the PSTN? So far we have to tell customer to 'press the buttons' for a little bit longer and it will work...

Hi. I have a SIP provider which wants RFC2833 for the dtmfmode, however I would like to increase the duration of the tone, its pretty short and some IVR's are unhappy or don't detect it. I did poke around, but it looks like when RFC2833 is used, it actually generates rtp packets of some sort, so I have no idea how to increase that duration. Any assistance would be appreciated. -- Your
