I'm having a strange issue and was wondering where I should start my troubleshooting. (We're using CallManager Express)
My receptionist tells me that during the week, randomly and intermittently, when someone calls the main phone line, the phone makes a short 'blip' sound and shows up as a missed call.
The night service setting was a suspicion but that's configured correctly everyday from 5pm to 8am the next day.
Has anyone seen this happen and could help me?
