If by default Asterisk ignores all polarity events, then why
does it cause the Dialplan to start?
I did set answeronplarityswitch to no, however, I have had
the problem occur once already, so, you suspicion might
be correct.

So, if the CO provides polarity reversal, why

You should not get that message on analog lines in the USA or Canada. I
suspect your line has a provisioning issue or is using different
signaling than you think it is using.

I'm running DAHDI 2.0 with a TDM401 card. Asterisk version 1.6.0.
It appears that I get this Polarity Reversal each time an inbound call
hangs up.

Not necessarily true. Most recent solid state switches have abandoned this as
a cost saving measure.
Polarity
Hi Jim,
We had this exact problem with our system for several years. A call
would come in with no caller ID and when we answered nobody would be
there. On the Asterisk console would be the Got event 17 (Polarity
Reversal) message.
We spent hours and hours on this. Our carrier was ATT (SBC).

interesting thing is that we didn't get the calls all the time but when
we did get them they were ALWAYS on the hour or half-hour.
Sounds like it may have been a line test. I vaguely recall a thread
going on here about such tests causing issues.

Tzafrir,
Thanks for the tip. I'm researching answeronpoliaryswitch. I suspect
this will solve my issue. I never would have know to look for this.
Thanks much! You made my day :-)

Hmm... I might have misled you. By default
