We have some phones in shipping/receiving and production which are fairly loud areas. Our building is 100% VOIP, so no chance at easily doing analog line via ATA. And setting up a SIP server for 2 ringers using something like Algo Solutions 8180 SIP Audio Alerter and/or Weatherproof Horn For Telephone Loud Ringing and Paging Notification seems like overkill.
Has anyone set up a warehouse ringer/alert light for Cisco VOIP phones?
