Glad I am not the only one! I have Comcast and have good speeds. I called today and VOnage set my packet size down to 10.
Made a call and still have the problem. Using a corder phone

I'm not an engineer, but I don't see how low ring voltage could cause a cordless phone's microphone (which is powered by its battery power souirce) to go "mute". The base station also has its own power supply. And switching to a corded phone didn't change my symptoms. Or am I not understanding the proposed solution?

Anyway, days ago I monitored my outgoing packets and they were still being sent at the same frequency and same size when the other party reported that I had gone mute to them. So, my RT31P2 was still uploading packets. I didn't capture the packet contents to see what was inside, nor capture the headers to see where they were going in case the address suddenly changed for some unknown reason.. I guess I'd need to capture 5 to 6 meg of data a minute for 20 minutes or so and then analyze the packets. Whew!

Add me to the list with this problem. Every call now. Before it was only 1 out of 10 calls.

We're using Comcast in Atlanta with a Toshiba PCX1100 Modem. Bandwidth tests good. Using a corded phone plugged into the RT31P2. QoS is enabled with 512KB. Wife is on the warpath.

when and if this problem is resolved, you can probably fix your previous issue(s) by replacing that pcx1100.

Thanks reebok. I did some more research after my post and saw that someone else fixed the problem by getting a new modem. I'll give that a whirl.

If you don't mind, can we get back on the topic? The problem has definitely been resolved and the output of the RJ-11 phone jacks were proven to be insufficient to drive some telephones. It is like trying to drive a 7 REN load with a 4 REN supply. Things start behaving strange. This is why swapping out phones worked for some and not for others.

A Vonage Rep. altered the output capacity of my phone adapter and everything has been working quite well with 4 phones on line where not even one would work before.

The knowledge of this problem has now been reported to the very highest departments in Vonage. A fix is promised in the near future.

I thought you all might like to hear this.

OK, after nearly a week without problems, the dreaded one-way audio problem was back today, and only for outgoing calls. It's fixed always by resetting my PAP2 adapter. Sad

If this is a known issue with low voltage (or for that matter, something else), can I please get someone from Vonage to respond to me and/or this forum and at the very least acknowledge the problem and if a known solution exists, please let us know!

Thanks.

I have been having problems with the One Way Audio for about 1 month. It was always on outgoing calls and not on incoming. I had a Motorola SB4200 cable modem with Charter Cable. My Motorola Vonage Box is attached directly to the cable modem.

Anyway, I think my problem was packet loss. I bought a new Motorola SB5100, which has DOCSIS 2.0 instead of the 1.1 with the older SB4200 modem. Ever since upgrading my cable modem, my Vonage has been working again.

With the older modem, I was having the problem on at least 2 out of 3 calls.

I'm not sure this would work for everyone, but it at least has fixed my problem.

Good luck -- it seems we're on our own on this one. Vonage hasn't helped out much on this topic.

Running out of ideas, I decided to call Comcast tech support yesterday and actually got a fairly knowledgeable Level 1 tech (!). I explained my problem to him and asked if I could swap out my (rented) Terayon TJ715x modem for a Motorola SB5100, since some people have reported better success with this brand of modem. While we were on the phone he tested the connection back to my cable modem and found that my transmit power was a little out of spec. He then scheduled a tech to come out tomorrow (Thursday) to replace the modem (although there's no guarantee what model I'm going to get) and check the connections.

In my opinion, I still believe that this problem was caused by a recent firmware update to the Linksys PAP2 and the RT31P2, but of course I can't prove it and I can't get anyone at Vonage to admit it.

I'll let you know how I make out after Comcast comes out tomorrow, although because the problem is so intermittent, it may not re-occur for a few days,

Regards,

D.

At the suggestion of a Vonage rep, I reconfigured my network topology putting the RT31P2 directly behind the SB5100 modem rather than secondary off a Netgear WGR614 lan port. Have made and received "long winded" calls of 50 minutes each without having the "auto mute" bug. Before, we could only average about 18 minutes before having to redial because they couldn't me but I could hear them.

I'm still really confused on the QoS to set in the RT31P2 as in order to have any upload capability at all while on the phone, I had to set it to a number that doesn't seem to make much sense.

Anyway, I'm still testing this topology but looks more promising than anything else that I have been tried. But it also means I just can't simply take the phone adapter with me on a trip.
