odoo plugin and customization needed

Hi, we would want you to develop a pre-existing open source plugin built for older odoo community edition and update it to latest odoo(11 version). For Phase 1 We would need you to upgrade the below telephony connector to odoo 11, which will enable us to connect our telephony system to odoo 11 the plugin is available at [login to view URL] In addition to the plugin we need an extra feature which enables us to view call recordings of all the calls made on that telephony system within a module of odoo. We are looking for a developer on a long term basis for odoo community addition development on an hourly basis and will be hired repeatedly upon successful completion of Phase 1. Please list your previous experience and if possible please share us the URL so we can have a look at your work. After successful completion of phase 1, we will proceed with the next 2 phases. Phase 2 will be user login security, also available as open source plugin. Phase 3 would consist of Mod Tracker, Audit trails, etc. Please quote for Phase 1 alone.
