I have no ideas about how to look at whats going on with your network. But I have a ?/observation. I noticed you said you switched from comcast to astound. Although I can't find anything to confirm this after a quick google search. Comcast and Astound are very, very, very, similar. I notice that they offer the same Channel package lineups, they both have the feature called Ondemand, their equipment and menus and guide all look weirdly similar. Looks allot like Cox, and Comcast down in southern California. I have a feeling that these two companies are somehow intertwined, maybe astound has bought a piece of Comcast's infrastructure?  This being said I don't think the switching of the service provider will really change anything unless moving to a AT&T or sonic...etc

Subject: [sf-lug] Is there a way to...

Is there a way to analyze the traffic through my router? I'm not sure 
that I'm asking is correctly, so let me set up a scenario: I've been a 
Vontage customer for a little over a year now. Up until a few months 
ago the service was crystal clear. However, a few months back I notices 
that the calls are not choppy, evidence of packet loss I suspect. 

I switched ISP's from Comcast high-speed to Astound. I had anticipated 
that this might resolve the issue, but it hasn't. It's occurred to me 
(and forgive the conspiracy mindedness of this statement) that since 
both Comcast and Astound provide VoIP services of their own that they 
maybe lowering the priority of VoIP packets on their network. Granted, 
they wouldn't lower the VoIP packets of their own service, so this 
theory is dependent upon them being able to shape high-speed data 
traffic separate from the VoIP service they offer. 

I realize I won't get a straight answer if I call either of these 
company's: are they really going to admit to interfering with traffic? 
So I'm wonder if there is a way in which I could analyze the data stream 
and see if I might be able to identify a trend in packet priorities or 
something of that nature. 

I know that we are able to capture network traffic trends within my 
office using a solitary hub (old-school, not a switch) and wireshark. 
Is this the same type of method I'd likely need to use? 

This is more a question of curiosity than criticality. Any thoughts 
would be appreciated. 

Cheers!
