I have (another) weird one. I have 4 VG248s in use but the 4th one (installed post cutover by vendor)is not working properly. Only 3 lines will register and with Publisher not Subscriber. All other ports "register: unknown". They are all set up with dns and when I check with butt set I get reorder tone. Any ideas or suggestions? Thank you inadvance for your time.
