I have a CentOS 5.2 box running asterisk 220.127.116.11 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 somwhat.
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.
