[asterisk-users] Question about queue

[unplug]

Hi,

I have set a queue 5000 with a agent 4444 logged in.  When an user
dial 5000, 4444 will ring and then answer the call.  Queue function
will execute and recording is started.  However, the recorded wav file
is not a valid file with just a few bytes.  Anyone can help me to
enable the recording function in queue?

    -- Executing MacroExit("SIP/2001-006bd8e0", "") in new stack
    -- Executing Goto("SIP/2001-006bd8e0", "sipcom|5000|1")
    -- Goto (sipcom,5000,1)
    -- Executing Answer("SIP/2001-006bd8e0", "")
    -- SIP Seeding peer from astdb: '2001' at 2001 at 10.0.0.25:5060 for 120
    -- Executing Set("SIP/2001-006bd8e0", "MONITOR_FILENAME=1155691672.29")
    -- Executing Queue("SIP/2001-006bd8e0", "5000|t")
    -- Started music on hold, class 'default', on channel 'SIP/2001-006bd8e0'
    -- Called Local/4444 at sipcom
    -- Executing Dial("Local/4444 at sipcom-a9a0,2", "SIP/4444|40")

In CDR, there are two records about the queue.
lastapp,lastdata,duration,billsec,disposition,uniqueid
