Salvete! I have about 12 Polycom IP 401’s that are on the blink (Asterisk 1.2 - I know, I am upgrading). One of the techs decided to pull the plug on the backup battery (which was dead) in the network closet in order to show someone what the plug looked like. The POE switch died, and ever since then, (for the last month) all the phones on one whole floor have stopped working. They won’t call nor receive calls. Now, all phones receive their ipaddresses from the dhcp server, and I have double checked them that they are getting the right ip addresses.
What can I do?
