[Asterisk-Users] wellgate 38XX with VAD and call files

[Jerry Geis]

Has anyone configured the wellgate 38XX sip units with VAD?
I have the unit all working but when I do a call file from
/var/spool/asterisk/outgoing/callfile (below)
--
Channel: SIP/1001/506XXXX
Context: smvoice-dialout
Extension: 99999
Application: Playback
Data: demo-congrats
--
Where 506XXXX is my cell phone number.
The demo-congrats message is already playing before I answer the call.
What is the trick to have VAD correctly work so the message does not
start to play before I answer the phone.

Thanks,

Jerry
