Had this happen to me yesterday. Receivers's voice was recorded than played back to to me in an infinate loop when I called back after disconnect. Web has several unanswered posts about this issue. Cicso VOIP routers have page dedicated to this issue. Known issue, but little is said outside telecom technical boards about problem. Very creepy and NSA-ish.
