[asterisk-users] Delay between DTMF Down & Detected Digit
Good Morning,
I've recently gotten Asterisk installed and configured our IVR using
FreePBX. Things seem to be going well except a few of our inbound
callers are ending up in the wrong place when trying to connect to a
specific extension. The example I had this morning was someone trying to
call extension 212 and getting connected to the Sales queue which is
option 2 on the IVR. I looked in our log and it seems like there was a
seventeen second delay between the caller pressing the last 2 and when
Asterisk acknowledged it. By that time, Asterisk had decided that "21"
wasn't a valid extension and the subsequent "2" dropped the caller
into
the Sales queue.
I did my best to search for this issue in the archives and I found one
reference to relaxdtmf, but I wasn't sure if that would address the
issue and I wouldn't want it to cause talkoff.
For reference, we're using a Wildcard TE410P for these incoming calls.
I've included the configuration for the ivr and a scrubbed segment from
the log. If any additional information is needed, please let me know.
Any help is appreciated in advance!
Jon

[asterisk-users] Re: Delay between DTMF Down & Detected Digit
I have seen this before if the caller is on a cell phone with too high of an audio delay. There is a delay for them to hear the end of the prompt, and then a delay for them sending the digits. -- -- Steven http://www.glimasoutheast.org "Jonathan Campbell" <jcampbell@remindermedia.com> wrote in message news:45520B4D.3060800@remindermedia.com...> Good Morning, > > I've recently gotten Asterisk installed and configured our IVR using > FreePBX.
