voice mail program

I am using vicidial for doing automated robocalls at night when the B2B customer is not open and I will get their voicemail. I have 110,000 phone numbers to call bi-weekly. The problem I need to overcome is detection as to whether I am calling: 1. a basic residential type answering machine or 2. a PBX style answering machine which has 4 different ways of asking you to leave a message by pressing 0 or leaving a message for extension 101 or other combinations. The problem with the vicidial is that it will call and recognize that a machine answered and automatically leave a message in 7 seconds. This is cost prohibitive because 70% of my calls will go to the PBX style answering and the cost of making the calls would be 3 times higher than if I could eliminate then PBX answering machines which is a total waste of money and not affordable. I do have a vicidial tech for you to talk to and they have a vicidial programmer to interact with you. If you can do this job, leave me some message as to how and I will be in touch with you.
