[Freeswitch-users] B leg ringing when Caller hangup before answer

Tue Feb 17 22:48:22 MSK 2015

Hi Bote,

I use analog card named TDM400P and there are two FXS and two FXO on it.
You can find it from this url http://www.ryu.com.tw/image/A400P.jpg. There
is a white power outlet behind it.

I am setting it at freetdm.conf and freetdm.conf.xml. But I don't know
what loop
battery is.
Is there any setting I can use when I try to make a call in <extensions>
segement?

Thank you for your reply.

Best regards,
Charles
