[asterisk-users] DAHDI not detecting RINGING Status on the Channel

[Danny Nicholas]

It's not the DAHDI driver; it's the POTS service you are (presumably) using.
The DAHDI driver works fine with PRI/E1 interfaces, but POTS requires
"human" knowledge (it can't tell if a line is ringing/answered, etc).   The
only "reasonable" solution I can suggest for this scenario is a
polarity/silence detect to keep you from processing many minutes of silence
and other garbage.  LoopStart instead of KewlStart has been suggested in
some instances (possibly applicable to you since you are non-US).

Subject: [asterisk-users] DAHDI not detecting RINGING Status on the Channel

 

I am using an 8 port tdm card and also I implemented a dialer using a
.call file generator. As you know on the .call you specify the channel to
call and then the contex/extension/priority to let dial plan continue when
the call is bridge.
My actual problem is that when the call process starts, asterisk (DAHDI)
sets the channel as answered when the truth is that on the other side the
channel has not started to ring yet. My felling is that the DAHDI driver
cannot detect /understand the signaling of the analog line. Here is the
evidence and configuration settings. I live in Argentina BTW
