Migration from Avaya phone system to Cisco and have to interface a night bell. The Avaya phone system had a port configured as a Bell Type port. You would dial and extension say 2300 then the ring would be amplified overhead on a warehouse floor. Wondering how to configure the VG248 to interface this night bell that just plays a loud ring on overhead speakers when the extension is dialed. I setup the extension on a port on the vg248 but when I dial the phone rings but the night bell does not. Anyone have any information on where I should start?
