Having all kinds of problems with new VOIP phone system... dropped calls, intercom doesn't work, voice mail won't retrieve etc etc. My general manager turned a certain shade of purple and she* was ready to break someone's face. Hours talking to tech support, comcast et al. I upgraded my internet to 75mg but as it turns out, the dude** who installed the firewall only dedicated 5mg to the phone system!!! No freaking wonder it didn't work properly!! Who are these people??? * Please substitute 'they' for gender neutral pronoun if you are so inclined. ** My granddaughter and her friends call each other dude sometimes so I guess that's gender neutral.
