3CX API help with redirecting calls

[LuckyDog]

We have a C# application running which logs the in and outbound calls, but I'd like to be able to redirect calls which come to certain numbers based on the area code (to a specific business unit). I've read through the API documentation, but I'm really struggling to get this to work. Does anyone have any experience in this area which they could share with me please?

Thanks

Nick
