Vonage Yes, I agree that you can have cabling problem that can effect only out-going data
Yes, I agree that you can have cabling problem that can effect only out-going data traffic. But your cable modem can't tell if the packets you're sending and receiving contain latest photos of Pam Anderson or digitized snippets of your conversation with mom. Since web-surfing is all about download speed, Voip may be the only thing you do where you really need decent upload speed. You could surf the Internet all year and never realize you have a poor connection that only effects your upload traffic.
Consider that every Voip conversation uses both uploaded and downloaded traffic. When you talk, your voice is converted into IP packets and uploaded to Vonage's network. When your mom tells you to quit looking at pictures of Pam Anderson, her digitized voice packets are downloaded to your Voip box. If you had a poor cable connection that effected only uploaded traffic, for example, she'd have a hard time hearing you while her voice comes across fine using your connection's bigger download band-width. (Figures, eh?)
The problem I was experiencing (and was described by others earlier in this topic) was that when I placed an out-going Voip phone call, the audio quality, in both directions, was very poor. When I received an in-coming phone call, the audio quality, in both directions, was much better.
So what's the difference between in-coming and out-going phone calls? The way the call is initiated. For in-coming calls, the IP connection between Vonage's switching center and our Voip boxes is initiated by Vonage's network. IP connections in out-going phone calls are initiated by our Voip boxes.
Simple logic says that a general Internet connection problem would effect Voip traffic regardless of how the call was placed.
While the cable modems in our homes don't have the smarts to prioritize different types of IP packets, the cable company's router's and switches can. But if Shaw was secretly sabotaging Voip traffic for those customers who haven't signed up for their Voip QoS, would it make sense that they'd significantly mess with both uploaded and downloaded Voip packets only in out-going phone calls and not touch Voip packets on in-coming calls? I don't think so.
The simple fact is that there's been a network change, either in Vonage's network or in Shaw's, that has adversely effected the success with which our Voip boxes have been able to establish a solid connection with Vonage's switching network. For some reason, I think we're experiencing a lot of dropped packets in connections we initiate.
As far as the difference between D-Link and Linksys routers, it's not really worth debating. I think Linksys used to be mostly crap. I think that's really changed since Cisco bought Linksys. I've never had a problem with any D-Link equipment I've worked with. For that matter, it's been a long time since I've had any problems with Linksys equipment either. I think both companies make the same quality of equipment in the same price ranges. There's certainly a lot of other cheaper equipment out there. The problem is that both D-Link and Linksys make so many different models of routers that all perform a little differently from each other. With all these different models and the different applications in which they may be put to use, it's very difficult to compare apples-to-apples. We each have a router that's working well for us, but each may have sibling models that work like crap in our respective environments.
My Linksys PAP2 Voip box worked fine for more than 4 months while plugged into my D-Link router. Then, without any changes to the router, my Voip quality took a nose dive. All my other IP traffic is still working fine. The fact that a lot of other Vonage customers suffered the same quality dive at the same time is a clear indication that the problem isn't with my router. (If it is, Shaw has a serious routing issue! :-D )
The problem may not be caused by my router, but I'm wondering if, in the absence of a system-wide resolution from Vonage, I can solve my problem by "helping" my PAP2 initiate its connection with Vonage's switching network. Unfortunately, I can't get a clear description of exactly how the PAP2 handles Voip traffic. I think that adding the PAP2 to my router's DMZ is probably the one change I've made that's improved my out-going call quality over the past couple of days. I'm still searching for a detailed technical description of how the connection works.
