Hi VoIP Gurus,
I got a report from one of our agent and she had experience a ghost call. per her description, her phone ring and on the phone displays the number of the caller but she hears nothing upon lifting the handset. Sounds a one way audio, my questions are how can i determine if it is a ghost call? how will I troubleshoot and fix it?
Can someone provide me a documentation about ghost/phantom call.
Appreciate all the help.. Thank you!
