I am having some troubles with DTMF detection on zap channels when the
remote caller is calling from a noisy cell phone. It is actually
detecting multiple DTMF tones (usually 2 or 3) when only one is sent
(i.e. I press '3' and Asterisk is detecting that as '333'.) I
don't know
the exact situation with regards to signal strength, etc, but it seems
to happen more often from users located in other cities. Here is my
zapata.conf (I have tried with relaxdtmf set to yes and no, with no
difference.)
[channels]
usecallerid=yes
hidecallerid=no
callwaiting=yes
threewaycalling=yes
transfer=yes
echocancel=yes
echocancelwhenbridged=no
echotraining=yes
pickupgroup=1
immediate=no
callprogress=no
relaxdtmf=yes
signalling=pri_cpe
switchtype=national
context=default
rxgain=15.0
group=1
channel => 1-23
Has anyone else had and solved this problem?
