Web based Call center

Hi, I need a web based call center with following features. This software/web service needs to be in 2 main forms. 1) Fully automated service It should be capable of dialing through a database of phone numbers and playing a recorded voice message. This voice message is in 3 languages. So software should be able to prompt the user with language options to select from. For example it should play a voice record saying "Please dial 1 on your phone for language 1, dial 2 for language 2 or dial 3 for language 3". Then it should play the selected voice recording. All voice messages (including any instructional voice messages like "Please dial 1 on your phone for language 1..." etc ) should be changeable, meaning that we should be able to record a new voice cut and replace it with an old voice message. 2) Semi-automated service Where software dial the next phone number and allow the phone operator to speak with the user and select a voice recording to play based on users spoken language. There should be 3 buttons for 3 languages. User interface should be very graphical but very easy to use by a telephone operator. There should be a screen to input telephone numbers and to upload a CSV file to the database. System should generate full set of reports. Please send me a proposal/ technical spec indicating the programming language and the database you will use. Let me know if you need further explanation.
