Outbound telephone autodialler application with IVR to dial up to XXX worksites, each with Primary and Secondary phone number, some may have extensions.  Highly flexible recurrence functionality must be built-in to allow for various combinations of recurring outbound calls to each worksite.  Solutions that use open source applications preferred.  I anticipate that Freeswitch, SQL VB (or equivalent) and open-source Text To Speech will be required although bidders asked to provide details and alternate approaches.  *Please note that only reliable coders who communicate professionally, and regularly need apply*.  3 references will be required. Only coders who can commit to 3-week turnaround or less will be considered.  Project schedule as follows: i) After final bid accepted, Buyer will be available for questions and clarifications throughout, ii) Buyer expects solid beta *. exe file plus all source code and any scripts within three weeks, and will test for one week, iii) Buyer will then request fixes, to be completed within 3 days, iv) Buyer will expect finished *.exe file, plus all source code and will have all deliverables reviewed by a 3rd party for completeness, v) Buyer will pay Coder.  **Payment for this project will be one single payment after verification of all deliverables**.
