I have installed a PA system utilizing the Snom PA1 and a Valcom V-1080 speaker. The PA1 is powered by POE. The speaker is powered separately. I can push the IP button on the PA1 and the ip address is announced. The status in 3CX is unregistered. The status lights on the PA1 are illuminated. One is red and the other is green. One problem is that when I open a browser and go to the IP address it opens but seconds later it is unavailable. I only have access to the PA1 for a few seconds each time I plug in the POE ethernet cable and then after a few seconds I cannot connect to the web interface.
