I'm trying to setup an a wakeup message on an Avaya Definity cabinet using an external announcement device. Can I use an available port from my TN763D aux trunk card to my wake up message? If yes....How do I configure the System Hospitality form to point to the aux trunk card port? Annoucement Type gives me the following options: external, integrated, mult-integ, music-on-hold, silence and voice-synthesis. I tried ding external but it would not allow me to enter the aux trunk port. Thank you for your help!
