Vonage Before you can come across like you know about the SIP protocol or VoIP technology
Before you can come across like you know about the SIP protocol or Voip technology in general, you have to first understand the difference between a dropped call is and dropped audio. That is why I posted the other posting. A dropped call would indicate that something sent a SIP BYE message. This does not happen until one of the parties hangs up. Dropped audio can happen if any piece of hardware restricts the flow of RTP packets causing 1 way or no audio. After saying "Hello, Hello, Hello", the party then hangs up and call is then physically terminated.
This has absolutely nothing to do with a few packets dropped here or there. This has to do with the complete RTP stream being filtered or rate limited. This does not mean you would have choppy audio
This means that during a call, RTP packets are streaming like a flood to provide real time audio. If for any reason this stream is completely filtered out, your going to loss a complete portion of audio in either one or both directions.
I deal with this type of thing every day for years and I can tell you right now, I am 100% sure the culprit is your Netopia Modem/Router. Since you state that this has been going on since you have had Vonage, have you ever tried to swap out this Netopia for a standalone bridged modem?
Right now, you have absolutely no idea what functions the router in this modem are performing and from years of experience, these Netopia's are problematic and difficult for a basic user to configure. The Telnet interface has many things that can be configured, disabled, or enabled.
My recommendation is to get a DSL modem that can easily be placed into bridge mode. This way it does not perform an DHCP or router type functions. The Vonage adapter is connected directly to this modem and your PPPoE information is configured on the Vonage adapter. This will eliminate any upstream hardware interference and provide best possible QOS.
