Java VoIP / SIP implementation for phone number validation -- 2

We search for a expert to implement a VoIP SIP validation of a list of phone numbers. As a result of the validation we need as much as possible details about the given number. The goal is to reduce the manual effort of a call center by knowing if the given phone number is a valid or invalid one. Also it would be nice to know what type of availability/unavailability was the result of the phone validation. As a input you will get a CSV list. Your implementation shall be in Apache POI 3.14 and the column containing the phone number shall be configurable by a the column header name. We do not need a database, since we have a custom implementation. BUT your model classes have to properly designed to be later able to use it easily with a custom persistence layer. To ensure you are not a simple poster please add the result of eight power two on top of your application. As a result we expect to get a updated CSV file with the new columns which you need to provide for the end user to understand the status of the phone number validation. Ensure that your implementation has a component for CSV reading, one for VoIP validation and one for CSV writing. Ensure the components are independently usable! We prefer for VoIP / SIP Java Standards. As a runtime environment we expect runable on: - in JavaEE 7 (wildfly 10) - Java 8 As the development environment we expect: - Eclipse Neon - maven Your delivery artifacts: - eclipse full project(s) incl. configurations and settings - a fully working [url removed, login to view] to build the application as a single & runnable jar - we share you a source repository for delivering the milestones With your application provide us following details: - delivery date for milestone 1 - brief class level design with public methods - a list in word or excel of statuses collected for the later VoIP validation (see also [url removed, login to view]) - one or a set of configured eclipse projects in our source repository ([url removed, login to view](s) are already part of the delivery) - delivery date for milestone 2 - working VoIP calls, no extraction of validation results - delivery date for milestone 3 - working validation extraction and implemented CSV writing Questions to you for the application process: Are you fine with our application process? - reviewing your CV and your application - providing you a questionaire about your skills and experiences - signing a NDA and customer protection - personal interview (please provide CV!) What delivery dates do you have for the given milestones? Assume you will start from [url removed, login to view] What VoIP/SIP library do you plan to use? To be clear a simple regEx validation like with [url removed, login to view] shall be done in front of the VoIP checks, but they are not enough! RegEx does not check the real phone status.
