BlackBerry Auto Attendant

We need for our company an app on the blackberry that would act like an auto attendant. It would play a greeting message and have options for the caller to choose. The owner of the app could decide how many extensions and what each extension is for and how to connect. There would be hour options with different messages depending on hours (working hours and closed hours) - Forward to voice mail if no response. - Be able to connect live on same phone if I should choose. - play greeting and have different extensions with more different greetings. (we supply of course all the audio) - play on hold music when customer on hold during a call This is an example of options needed. If your able to create something like above . I can specify exactly all the options and details needed.
