Hi All, I encountered a DTMF problem. We have an IVR built on Asterisk 1.0.7 with RedHat 9. When the caller calls into our IVR, and IVR plays the first prompt and asks caller to dial four-digit extension. Caller has to dial slowly, otherwise, Asterisk cannot recognize the extension number. I look at the trace on Asterisk CLI and there are missing digit in the middle of string. ex, caller dials 3114, I can see 314 or 34 on CLI. I think the Asterisk barge-in response is vary slow, it usually takes half a second or so for the voice prompt to stop after the first key is hit. If a second key is hit when the prompt is still playing, this key will be missed and will not feed into the Asterisk IVR. However, Asterisk will be able to recognize all the keys if you wait long enough between the 1st key and 2nd key (and you can hit as fast as you can between 2nd, 3rd & 4th key). I searched the wiki and did not find any related information. Is there a way to set the barge-in response time or how many keys you can buffer before the prompt is stopped ? Please advise, Thanks and Regards, Larry
hya, try using relaxdtmf=yes in zapata.conf and see if that solves it. checkout these recent postings as well: http://lists.digium.com/pipermail/asterisk-users/2005-August/122737.html http://lists.digium.com/pipermail/asterisk-users/2005-August/122656.html cheers On 9/5/05, larry lin <lar_lin@hotmail.com> wrote:> > Hi All, > > I encountered a DTMF problem.

Thanks maka and sorry I just saw your email (too many in my account). I set relaxdtmf=yes and going to try it. Thanks again.
