Looking for a high-volume auto dialer that is capable of dialing over 1,000,000 phone numbers per day. When people press 1 to confirm their interest, the system will need to Dial a partner's phone # (DID) and blind transfer right away with the caller ID (blindxfer, unless other method is recommended). Speed is critical and the system will likely need to be a pure-Asterisk system with no extra fluff, and a custom dial plan. System needs to be able to handle 300-500+ outbound channels at once with large rate of playback (and hopefully outbound transfers as users press 1 to confirm). Ideally we want to dial out 1-5mil numbers per day and transfer/connect 1-10k press-1's to agents, reliably at-will. If this sounds like something you might've already built in the past or have lots of experience with, please apply for this job. Need a basic solution in place by tomorrow morning if possible, with further refinements over the weekend.
