Callshop telephony programme

We wish to have a telephony programme developed for callshops. The product must have all the usual stats and reporting functionalities of calls made, money made over time, multirouting between different carriers (if possible), ... The user-friendliness of the programme is important as is the kind of switches it has to support: Parlay and Immix most notebly. It has to be able to take prepaid money from users and manage calls so they cut after their money runs out. VB 6.0 would be the preferred language, although we will consider any other language. Thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform windows
