I have a somewhat unique customer request. Or at lease unique to me. I have a customer that is moving off of a Nortel PBX to our CCM cluster. Currently they have a phone number that rings to a central phone in a pick up group. If no one answers the phone and the caller leaves a voicemail message, the MWI triggers a strobe light to flash. Has anyone come across this before and know how to duplicate it on the Call Manager? I'm going to try and duplicate it using an ATA, but I don't know if I'm going the right direction with this.
