ports.
Description: 
Continuation of https://issues.asterisk.org/view.php?id=15311 which is
specifically related AsteriskNOW 1.5

If a call to a FXS port on a TDM400P is picked up while ringing (not
silent period), after 6 seconds of the pickup a click is heard, and it's
reported that sometimes this causes a hangup.

Alec, 

I was able to reproduce the following on the wctdm and wctdm24xxp
drivers.

Here is my scenario

My fxo line is configured so that it waits 4 seconds, answers, then loops
through a playback.
I have two FXS lines in which FXS2 is looped back the FXO line.

I have fxs1 (dahdi/9) call fxs2 (dahdi/10) which connects to the fxo
(dahdi/1).
Before the call is answered by the fxo (i.e. it is executing wait), I
hangup fxs1 which hangs up both fxs1 and fxs2
The fxo diaplan continues to execute with a simple switch thread started
on fxs2

    -- Starting simple switch on 'DAHDI/9-1'
    -- Executing [7770 at default:1] NoOp("DAHDI/9-1", ""Call dahdi10"") in
new stack
    -- Executing [7770 at default:2] Dial("DAHDI/9-1", "dahdi/10") in new
stack
    -- Called 10
    -- DAHDI/10-1 is ringing
    -- DAHDI/10-1 is ringing
    -- Starting simple switch on 'DAHDI/1-1'
    -- Executing [s at dougfxo:1] NoOp("DAHDI/1-1", ""Doug's test context"")
in new stack
    -- Executing [s at dougfxo:2] Wait("DAHDI/1-1", "4") in new stack
    -- Hanging up on 'DAHDI/10-1'
    -- Hungup 'DAHDI/10-1'
  == Spawn extension (default, 7770, 2) exited non-zero on 'DAHDI/9-1'
    -- Hanging up on 'DAHDI/9-1'
    -- Hungup 'DAHDI/9-1'
    -- Starting simple switch on 'DAHDI/9-1'
    -- Executing [s at dougfxo:3] Answer("DAHDI/1-1", "") in new stack
    -- Executing [s at dougfxo:4] Playback("DAHDI/1-1", "tt-weasels") in new
stack
    -- <DAHDI/1-1> Playing 'tt-weasels.gsm' (language 'en')
    -- Starting simple switch on 'DAHDI/10-1'
    -- Hanging up on 'DAHDI/9-1'
    -- Hungup 'DAHDI/9-1'
    -- Executing [s at dougfxo:5] Wait("DAHDI/1-1", "10") in new stack
    -- Executing [s at dougfxo:6] Goto("DAHDI/1-1", "looper") in new stack
    -- Goto (dougfxo,s,4)

Is this the scenario you are talking about?
