I have a system with 6 media gateways to support a mixture of analogue trunks, CAS trunks and ISDN trunks. 3 of the media gateways have ASU's and there is a +1 in a small chassis. I want to connect an application to the MXOne which uses two CSTA-III interfaces. These monitor and control the calls in several queues in which incoming calls can be presented from each of the media gateways at the same time. Also, there are IP extensions defined "in the system". The question is: Do I need to have a physical CSTA-III connection associated with each ASU or can I just make 2 connections to 2 ASU's and still monitor and control all of the lines regardless of which two of the three ASU's that I connect to?
