Wow, finally some action on TEK-TIPS.com for Aspect! This is great!
Shan, I understand what you are trying to do, and I bet with enough time and money you could develop an outbound service to do this in Unified IP, but there are several caveats.
I'm assuming you are in the collection industry. I think you want to make an outbound preview service, that presents the LYRICall user with several phone number options. After Aspect dials the first number, the agent will disposition the call as a successful hit on the collectee or a dead-end. Then it is simply a matter of Rinse, Lather, Repeat until the dialer presents each possible phone number for the collectee to a preview agent and let's the agent decide if they found the right phone number. It sounds like you may be trying to call all the phone numbers at once, whereas you may actually need to institute a process of preview dialing each number one at a time. I am not even sure if doing this is legal in your state. I suggest you check on that. I love suggesting applications when I don't have to do any of the work! Did you contact Aspect Professional Services to see how they would suggest doing this?
