Hi Nanang, thanks a lot for your message. Let me include more code in this message. The code i put here is called only once for each inbound. For example, when the first inbound comes in, the code is called once in thread A; when the second inbound comes in, the code is called once again in thread B. Am i doing something wrong here?
thanks a lot!
