Vonage I have never had this problem with Vonage, but I have experienced delayed audio
I have never had this problem with Vonage, but I have experienced delayed audio cut-through on calls forwarded by some other carriers over the years. It is usually caused by a delay in the propagation of supervisory signaling from the called party.
In other words, when you answer the incoming call, the fact that you have gone off-hook is detected by the carrier serving the phone you answered (or by the cellular service provider who receives the radio signal from your cell phone when you answer it). This signal (called answer supervision) is passed by that carrier to the carrier who passed the call to them. If that is not the carrier from whom the call originated, it must then pass the same signal back to the carrier from whom it received the call, and so forth. The originating carrier, in some cases, does not cut through forward audio until they receive answer-supervision. If that signal is delayed, you experience the symptom you describe. The larger the number of intermediate carriers in a particular call, the more severe the problem.
This does not happen on all calls because of differing network architectures. If, for example, all of the intervening carriers are connected via the SS7 signaling network, then call-forwarding may pass the call directly to the terminating carrier, bypassing the intervening carrier who might have initiated the call-forward request. Also, some originating carriers do not block forward audio while awaiting the called party's answer.
