A coworker used my phone to make simple test call to himself by dialing his 4 digit extension from my phone.
Ever since that single call was made I see a phantom call initiated from my phone to his extension about every 5-10 minutes. I have a presence button of his extension on my VVX410 and I see it flash green.
Further, his phone never actually rings and after about 30 seconds it stops and the cycle begins again. I have check the call log and call history and these calls do not display. I have rebooted the phone and they still continue.
Anyone have any idea about this?
