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.

We're looking to have a knowledgable expert in IVR solutions, payment processing and proper PCI-compliance systems-engineering to aid us by building a complete solution using Asterisk and other open-source projects to create a full secure (and PCI-compliant) IVR payment system similar to the commercially available solutions. The system should be well-documented so that we can deploy it from scratch, and configure it fully with the main options. It should tie into both the Authorize.net and Stripe payment gateway API's and cover the general scope of a full end-to-end solution of being able to process credit cards, debit cards, ACH payments, and checks over the phone using the dial pad and verbal cues for auditing and proof-of-identity. For the right candidate, we will have much future work on other cool VOIP and PBX type systems, so we look forward to connecting with some experts in this field. If you feel you meet this description, please apply! TO MAKE CLEAR: ONE OF THE REQUIREMENTS FOR THIS JOB IS MAKING SURE THE ENTIRE DEPLOYMENT SEQUENCE IS WELL-DOCUMENTED SO WE CAN DEPLOY THIS IVR FROM SCRATCH OURSELVES ON A FRESH SERVER.
