asterisk users - Oct 2006 - S(x) - Hang up the call after 'x' seconds - Not working from queue

Hi,

I have a requirement to limit the calls to our agents via a queue to 5
minutes. I had posted this to a previous thread by name "Maximum
talktime in a queue?" One work around that was suggested was to use
the S(x) in the dial command to the agents, so that all calls to that
extension would be terminated after x seconds.

So I modified the dial command to the agent as:

exten => 1001,1,Dial(SIP/1001,,tS(30))

Now when I call 1001 from another sip phone in the same context it
get's disconnected after 30 seconds.

    -- Executing Dial("SIP/1002-b119", "SIP/1001||tS(30)")
in new stack
    -- Setting call duration limit to 30 seconds.
    -- Called 1001
    -- SIP/1001-b605 is ringing
    -- SIP/1001-b605 answered SIP/1002-b119
    -- Attempting native bridge of SIP/1002-b119 and SIP/1001-b605
  == Spawn extension (from-sip, 1001, 1) exited non-zero on
'SIP/1002-b119'

All is fine so far and it works as advertised. Now I am attempting a
call via queue:

    -- Executing Queue("SIP/1002-74e9", "Auth-Enq|t") in new
stack
    -- Started music on hold, class 'default', on channel
'SIP/1002-74e9'
    -- outgoing agentcall, to agent '1001', on
'Local/1001@from-sip-de56,1'
    -- Executing Dial("Local/1001@from-sip-de56,2",
"SIP/1001||tS(30)") in new stack
    -- Setting call duration limit to 30 seconds.
    -- Called 1001
    -- Called Agent/1001
    -- SIP/1001-d43c is ringing
    -- Agent/1001 is ringing
    -- SIP/1001-d43c answered Local/1001@from-sip-de56,2
    -- Agent/1001 answered SIP/1002-74e9
    -- Stopped music on hold on SIP/1002-74e9
  == Spawn extension (from-sip, 1001, 1) exited non-zero on
'Local/1001@from-sip-de56,2'
  == Spawn extension (from-sip, 99, 1) exited non-zero on
'SIP/1002-74e9'

This call does not terminate after 30 seconds. I hope I have currently
followed the tip from Lenz in my previous tip.

with warm regards,

raj

Someone correct me if I'm wrong: The Dial string is missing a '/n' 
parameter for the Local channel. Without /n, Asterisk will do a native 
transfer to SIP/1001 and lose the timeout value defined earlier.
