I have the trunk connected and seems to be fine. But the problem I am running into is getting the extensions to work. I am not seeing any of them connecting. I have grandstream phones. I would think there would be somewhere I should put in the ip address. I just can not get the phones to connect to the trunk. Once I get that done I think I can get the rest. PLEASE HELP ME

If you are trying to get phones registered to a trunk you are way off course. Read the getting start guide, phones are configured as either extensions or devices.
