I originally placed this under VoIP but have not received a reply. Maybe someone in this group will have an idea.
I have an anomaly were phones go to fast busy when caller makes a call (but not during the dialing) and when answering a call. At this point it is happening about dozen times a week and is generally not the same person as before. I have been unplugging the phones and allowing them to reboot to resolve the issue. I have tried to reset the phone from Call Manager and by using **#** and neither worked. Any thoughts on what might be causing this.
