I'm working through development of a generic ICM routing script that uses Service references by expression within a Route Select node, and I cannot figure out how the ICM makes a determination of which translation route to use for the service that is 'rendered' by evaluating the expression. When building the RS node, the translation route column in the configuration panel is not configurable--all you can do is mark it with an 'X'. Since I have more than one TransRoute for this peripheral (this will be a VRU-to-ACD translation route), I'm stumped about how ICM picks a TransRoute for that Service.
Also, if anyone has any suggestions about expression formatting, I'd like to hear them. The documentation on this is very scant.
