Disable "Drop Call Seconds" to play a custom message

[frank83]

Hello,
I started a predictive campaign in outbound, I play a message instead of dropping the call, but I've an issue, the call arrive after 9/10 seconds, why?
In the campaign i've set to drop call seconds to -1 and I set an ingroup to forward the call.
I noticed that there are 6 seconds since starting the agi-VDAD_ALL_inbound.agi to play the hold On Hold Prompt File, why?
Can you help me please?
