Out of interest, do you know the RTT from phone to server, and the size of the jitterbuffers?<div><br></div><div>Just wondering whether the lag is a result of the two combined. DTMF digits can also last a noticeable length of time (often ~400ms) and I believe get detected when they 'end'.<br>

<div>Yes, there is a bit of a delay between the the time the digit is entered and the time that it is officially detected and the playback of the IVR greeting is interrupted. I've not noticed that being a problem, other than people maybe wondering if their digits were not properly entered so they hit it again. Is that what is happening?<div>

Hi,<div>I am observing that when I use IVR menu, the main menu greeting does not get stopped as soon as I enter the dtmf digit. It plays for a couple of seconds longer and then stops and then the dtmf is processed. Is there any tuning parameters that I can tweak to make it stop sooner. </div>
