I can't register the GWX4104 I tried several times to register it, followed all the steps, revised all the conections, checked the server, upgraded the firmware, checked the password for all the lines, the server has 2 phones registered already, all IP adress are ok, I tried with two differents servers everything is in the right way but still doesn't get registered. This is a test that I'm doing at home and I wan't to isntall it at the office so if it works I'll install it on all the offices. But I'm stucked in something that I think it's so simple. Please help me out!!! Thanks in advance.
