Asterisk Now with Voice Broadcasting

We need Voice Broadcasting Solution as below Requirements: Flexibility, so we can add/remove/change campaigns easily. Campaigns of the following nature need to be supported: Predictive outbound dialing that returns back to agent. (We will be using a lot of channels. Will start with atleast 250 channels) [Provided by our ITSP, VoIP channels.] Voicebroadcasting. Playing message to humans, and pressing 1, it needs to come to the agent.. where either the lead will be closed, or transfered to an external number by way of extension, for ex: #2 will transfer to 1888-399-2222, etc. Voicebroadcasting same as above, with answering machine detection that will leave messages. Hopefully do all of this via softphone only. Don't really need the CRM of vicidial , etc Scenario: Options like the following in Web GUI: 1) How many channels? (100-250) 2) What file to play to answering machines? 3) What file to play to humans? 4) Press 1 functionality to file being played to humans? 5) Transfer press1s to agents or external number? 5) What callerid should be shown? Plz send me details about quotation and features you have for demo. I need here multiple users can connect with server with their individual userid and password to maintain their own campaigns.
