I have a new install at a police dispatch center. I am running into a roadblock trying to figure out the best way to do this. They want to have distinctive ringing for their incoming "emergency" calls as opposed to their normal business calls. The only way I can brainstorm to do this is to setup two extensions on the phones with the emergency incoming calls going to the second extension with a different ringtone. I would prefer to be able to do this through priority alerting but can't seem to figure out how to make it work. Any suggestions?
