Hello all,
I have one Asterisk 1.4.21 system connected to a North American POTS
line. Normally hangup detection works fine, and Asterisk hangs up
properly if you are talking to a caller and they hang up; but
occasionally a call comes in (typically from a US telemarketer) where
the caller hangs up
Here's also an example snip from the debug log:
[07:42:20] -- Executing [...@mainmenu:15] Dial("Zap/1-1",
"SIP/105|18|tKk") in new stack
[07:42:20] -- SIP/105-08571180 is ringing
[07:42:39] -- Nobody picked up in 18000 ms
[07:42:39] -- Executing [...@mainmenu:16] Answer("Zap/1-1", "") in new stack
