[Asterisk-Users] Digium Card: Echo, Echo and more Echo

[Matthew Boehm]

We have a TE110P (single span PRI) and are having tons of echo on all calls,
both incoming and outgoing. We didn't have any echo at all yesterday and
nothing in any of the configs has changed.

All of all calls follow this pattern:

    Cisco 7960 -> Asterisk -> PRI

Here is my zapata.conf

[channels]
context=all-incomming
switchtype=national
resetinterval = 3600
priindication = outofband
signalling=pri_cpe
usecallerid=yes
cidsignalling=bell
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=128
echocancelwhenbridged=yes
echotraining=yes
rxgain=0.0
txgain=0.0
immediate=no
faxdetect=both
group = 1
channel => 1-23

And my zapata.conf:

span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
loadzone = us
defaultzone=us

Any ideas? We are going to replace the Digium card with Sangoma card later
tonight unless anyone else can offer another solution or things to check.
