Dialer start playing asap

I need it to start playing message right as the call is picked up. (I don’t need to wait for human or VM, just start playing the recording)

Open Voicent Gateway, select Setup > Options > Detection Tab, select “Most Aggressive”. Once set, it will always play the message regardless of whether it is answered by live human or answering machine.

I need it NOT to hang up after the message is done playing for about 3-4 min. I don’t see where I can adjust that timer.

The hangup is not controlled by the software, it is a function of the phone service. For example, if you manually make a call using your cell phone, if the other party hangs up, your phone connection will be disconnected. Your phone company will disconnect the call even you have not hang up the call yet.

You could control the dialer to not dial the next number within the next few minutes. There is a disconnect time setting and interval dialing setting. To set these, open Voicent Gateway, select Setup > Options > Outbound tab.
