Half of our phones are down.

I work in a NOC (Network Operations Center) doing mostly tier 2, sometimes tier 1 troubleshooting.

Received a call from a site. They had some power issues due to a big snow storm.

U: I got our equipment back up, but half of our phones(VoIP) are still down.

M: How are they connected? Do the computers connect through the phones or do they have their own cables going to the switch?

U: Oh, I forgot that the media converters are powered by USB from the desktop computers, let me check if they are turned on or off.

M: *wait for him to check...it's always media converters*

U: Yeah, we're all set, thanks for your help.

M: No problem, have a good night.
