Hi Richard,

I've not experienced this problem but something off the cuff may be an echo
cancellation problem ???
Generally though I dont have problems with these cards using the latest Trix
setup
 All The Best

Subject: [asterisk-anz] Audio Issues with TDM400P in Australia


Hi

I posted the following message on the asterisk.org forums with no
replies so I thought I would post the message here to see if anyone can
help me.

I have a CentOS 5.2 box running asterisk 1.4.21.2 and zaptel 1.420-1. I
have a TDM400P PCI card with 1x FXS and 1x FXO. I have the system
configured in such a way that I can call from the FXS port to the FXO
which is plugged into my POTS from Telstra from provider. I also have a
VOIP account using SIP and connect to CNET (collectors network) with
IAX2 and SIP.

My issue I have noticed is when talking to some parties (generally
through the FXO port) the line goes quiet and then comes back to normal
and then goes quiet again. I am not sure why this happening and it is
frustrating me somewhat.

I wonder if the problem that I have is getting the zap drivers to set
the card to Australia mode. I have setup the /etc/modprobe. d/zaptel file
to specify "options wctdm opermode=AUSTRALIA" but when I run ztcfg -vv
and look at the ports I have kewlstart configured on the ports but no
AUSTRALIA.

In zaptel.conf I have configured loadzone=au and defaultzone= au and
fsoks=1 and fsxks=2.

In the zapata.conf file in the asterisk directory I have setup normal
line options but nothing seems related to Australia.

Anyone seen this before or can suggest something for me to try. I would
greatly appreciate it.

Cheers

Rich
