[Freeswitch-users] DTMF in IVR menu

I am using Counterpath's eyebeam and their documentation says jitterbuffer
is dynamic and cannot be configured. I don't have this problem with
play-and-get-digits, so I don't think the RTT is a problem. I was wondering
would tweaking the following parameters help in any way?

min_dtmf_duration
max_dtmf_duration
default_dtmf_duration

Thanks,
JP
