[asterisk-users] question on originate call

[Jerry Geis]

I have outgoing call files working. I am trying to get the manager to 
originate a call.
My outgoing call file that works looks like:

Channel: SIP/devcentos5x64_to_panel/mediaport
SetVar: MEETME_PLAYFILE=/home/silentm/record/pc.1725.wav
SetVar: agi_pa_recno=1725
Context: smvoice-dialout
Extension: smvoice_single_mediaport
Priority: 1
RetryTime: 2
WaitTime: 40
MaxRetries: 0
SetVar: SIPADDHEADER="Alert-Info: Ring Answer"
CallerID: Jerry Geis 204 <317>
SetVar: agi_port=
SetVar: agi_extension= TESTING
SetVar: agi_seconds_to_ring=40
SetVar: agi_dwc_record_num=43


The Manager API session looks like:
04-Feb-09 08:22 am asterisk_command() Action: Login
04-Feb-09 08:22 am asterisk_command() Username: MessageNet
04-Feb-09 08:22 am asterisk_command() Secret: XXXXX

What am I missing to get the manager API to place the call instead of a 
call file?
Thanks,

Jerry
