I have a MICS 7.0 that just got a dynamic curcit. It has security upgrades. The phone company is telling me that I need to --Pass Redirect Message--I 74 a ISDN information element--- to make the call forwarding to work. It worked before. They are telling that they are not letting the call forwarding go through because they are seeing the number that is calling in and it is not a number that is a belongs. How do I fix this? Thanks
