Outbound/Call Progress Detection

[Vivek]

I developed an outbound application, which initiates calls, once customer picked up the call it plays an announcement. I used predictive dialer.

I'm getting a delay between after customer picked up the call and start to play announcement. I heard the delay comes from Call Progress Detection in Switch side.

Does anyone know how to minimize the delay?

I would like to add one more infomaiton, we are using Lucent G3 Switch.

If are using G3, chances are you are not using CPD server.
The progress detection delay in G3 was 3 seconds if I am not mistaken they need that to distinguish between answering machine and a human voice. As far as I know, removing that delay would make it impossible to distinguish between AM and a human.
If you think you can get by with AM detection then just have it removed by PBX people.

Thanks for your info.
I am getting 9 seconds delay. That is between a customer picked up the call and start to play the announcement it takes 9 seconds in my case. Genesys tech Support has confirmed that the delay is in CPD. The usual delay should be 3seconds?

Have your PBX people play with AMdetection.
In the States, AMs issue a tone to identify themselves when they first start, making it much easier for PBX to make the distinction.
