Hi,
I have had an issue for a long time, and really just can't solve it.
My boss and others seem to have a problem when they call into our
asterisk phone system. It often takes 3-4 tries of entering an
extension before the system gets it right.
Below is my context that the call comes into, and some debugging
from the asterisk console.
You may want to add the following to the zapata.conf
; If you are having trouble with DTMF detection, you can relax the
DTMF
; detection parameters. Relaxing them may make the DTMF detector
more likely
; to have "talkoff" where DTMF is detected when it shouldn't be.
;
;relaxdtmf=yes
I have found that relaxdtmf=yes has caused more problems than it
fixes. In my experience problems with detecting DTMF on an FXO port
can usually be fixed by playing with rxgain and txgain.
What sort of problems have you seen it cause? I guess I could see
hitting the wrong extension in rare cases. Anyways, relaxdtmf has
worked wonders for me over T1s and analog lines (always seems to be
cell phones that have issues, probably because of the GSM and radio
distorts beyond the specs).
It caused asterisk to see a single digit when two of the same digits
were dialed in a row. So a user dialed 4415 and Asterisk saw 415.
Remember that on all cell phones (except the analog ones) DTMF from
the phone is sent out of band and so should not be distorted.
Are you sure about that?. I think that the DTMF digits are send out of
band before the answer supervision. After that, the DTMF digits are send
in band if they are dialled from the keypad. When I call my IVR, the
system answer and I dial other DTMF digits, only around 20% of calls
succeed. However if I store the DTMF sequence in the cell phone (digits,
pause, send, digits, etc.) 100% of calls succeed.
