Summary:                    Wrapuptime sometimes not respected
Description: 
Ever since at least asterisk 1.6.2.5 we are experiencing that occasionally
(perhaps every 1 out of 10 calls) our WRAPUPTIME is being ignored. I
finally got around to setting up an environment where we can somewhat
reproduce the issue. This environment runs 1.6.2.13.

First of all, all the relevant parts of our configuration:

--- queues.conf ---
	[general]
	shared_lastcall = yes

	[queue1]
	ringinuse=no
	wrapuptime=60

--- extensions.conf ---
	; we only use dynamic agents, through a local channel because we need to
do AGI processing before and after an agent is called
	; because of the local channel, we specify a custom state interface that
we set INUSE/NOT_INUSE in the phones context
	[login]
	exten =>
s,n(login),AddQueueMember(queue1,Local/${extension}@phones/n,,,,Custom:inuse-${extension})

	[phones]
	exten => _X,1,Gosub(callphone,s,1(${EXTEN}))

	[callphone]           
	exten => s,1,Set(DEVICE_STATE(Custom:inuse-${ARG1})=INUSE)

	exten => s,n,Dial(SIP/phone${ARG1})

	exten => h,1,Set(DEVICE_STATE(Custom:inuse-${ARG1})=NOT_INUSE)
	
Most of the times this works fine. An agent hangs up a call, and gets (at
least) a 60 second pause before another call is offered to him. But
sometimes, RIGHT after an agent's call is hungup (to be exact, it happens
right after the Custom:inuse devstate is set back to NOT_INUSE. at this
time the call hasn't fully terminated yet by asterisk), the agent is
offered another call. See for example:

	[Sep 30 15:06:10] VERBOSE[9694] pbx.c:     -- Executing [h at callphone:1]
ExecIf("Local/99 at phones-78e9;2",
"1?Set(DEVICE_STATE(Custom:inuse-99)=NOT_INUSE)") in new stack
	[Sep 30 15:06:10] VERBOSE[9694] pbx.c:     -- Executing [h at callphone:2]
AGI("Local/99 at phones-78e9;2", "hangup.agi") in new stack

	[Sep 30 15:06:10] VERBOSE[9701] pbx.c:     -- Executing [99 at phones:1]
Gosub("Local/99 at phones-fa31;2", "callphone,s,1(99)") in new stack
	[Sep 30 15:06:10] VERBOSE[9701] pbx.c:     -- Executing [s at callphone:1]
ExecIf("Local/99 at phones-fa31;2",
"1?Set(DEVICE_STATE(Custom:inuse-99)=INUSE)") in new stack

	[Sep 30 15:06:10] VERBOSE[9694] pbx.c:     -- Executing [h at callphone:3]
NoOp("Local/99 at phones-78e9;2", "") in new stack
	[Sep 30 15:06:10] VERBOSE[9694] pbx.c:   == Spawn extension (callphone,
s, 15) exited non-zero on 'Local/99 at phones-78e9;2'
	
When this problem occurs, it always occurs after the previous call has
been hungup: in the same second. Never later than that. Perhaps the
wrapuptime is being ignored when the queue engine tries to offer a call at
exactly the same moment that another call is being hung up. Any clues?

(Yeah, we do. There is a bunch of logic - AGI scripts etc - in the
callphone context before the Dial() is executed. If we use the SIP address
as stateinterface; the agent won't be marked as busy until the Dial() is
reached, and there's a chance the agent will be offered multiple
simultaneous calls)

This bug can probably be closed.
