One-Way Audio

The problem has been too intermittent at my home to declare it fixed after only one day. Let's see what happens in the next few days!

While you're all scratching your heads and passing insults to people who just might be able to help you out, just keep banging your heads against the wall. I had this problem and I solved it. I spent a week testing and testing and testing some more. My phone works now. Nobody helped me, nobody wanted to. I have the answer that you're looking for.

I apologize if my postings in this thread have "insulted" anyone as mbhn5204 has suggested but I'm just a very frustrated Vonage user who many months ago dropped his standard telco line for Voip service. All was working fine until a couple of weeks ago when I started experience the one-way audio problem. By way of this thread, it became evident that I was not the only one to have this problem, and it wasn't isolated to one provider, modem, router, or even telephone.

Vonage's standard Level One tech support response to check your bandwidth is just unsatisifactory. If there is a widespread problem, and it certainly appears that there is, I just want Vonage to acknowlege it and tell people that they're working on it. Am I being unreasonable?

mbhn5204, if you have truly solved this problem like you claim, you are doing many Vonage users besides myself a disservice by not disclosing your fix.

No, it isn't fixed for me today. Went "auto mute" a three times ... once 8 minutes into a call, another time 11 minutes, then the last call tonight made it all the way to 21 minutes. Using a corded phone makes no difference for me... it still goes reverts to one-way audio... and even if that fixed the problem, it would make the Vonage service undesireable with such a limitation.

one-way audio can be traced to a NAT issue on one end or the other. The audio portion of a Voip call travels on a different port than the signaling (at least in SIP it does.)

When a voice packet from person A leave his ATA/Phone, it contains the destination IP/port of person B. If person B is sending his contact-header as an internal IP, then when person A sends out a voice packet to person B, that packet's destination is an internal non-routable IP and gets blown to oblivion and never reaches person B; thus one-way audio.

Thanks for the reply. If this is truly a NAT issue on the Vonage user's end it shouldn't be intermittent and might point to a problem with the adapter and/or the router (hardware or configuration issue). I'm using a PAP2 with a WRT54G, but some of the others that have posted in this thread have reported using other hardware.

I have alerted a Vonage Representative and asked him if he wouldn't mind helping you all out with this. Between us, we seem to have arrived at a solution. A few more days of testing will prove it out.

I am a Vonage customer, and I have experienced the same one-way audio problem. I am also a policy advisor working in Washington, D.C., and I happened to see Jeff Citron (Vonage CEO) earlier today. I asked him about the problem and he assured me his folks were working on the problem. I didn't have time to go into a discussion of the potential solutions (and I'm not a techie, so I wouldn't have understood anyway), but at least I left with some confidence that it was on his radar screen.

heh, and what would you say if a customer of your business came up and asked about a problem?

Agreed,. Let's just hope that he's sincere and has known about this problem.

One can only hope!
