[Asterisk-Users] Intermittent echo and clicking sound

[Goutam Shaw]

Hi,

I am experiencing 2 intermittent problems:
- echo problem (which fades away quickly) and
- a clicking sound every 20-30 seconds. Is there anything that I can do to
avoid this nuisance.

The phone is BT101 and the FXO card is TDM04B and the Zapata settings are:

switchtype=national
signalling=fxs_ks
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancellforward=yes
callreturn=yes
echocancel=yes
echotraining=yes
echocancelwhenbridged=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1
immediate=no
callerid=asreceived
callerid=asreceived
channel => 1-8

Regards,
Goutam
