I am still having problems with my VOIP quality. I have run a trace route, and from a site that I have run it from, 17 hops which the site I have run the test from says is relatively high which can cause problems.

Also when I ran the test it seems the problem might? be with ooma. On three occasions the ping at Ooma was in an "erratic behavior" ranging from 63ms to 276ms.

Another test I ran said that a different site was acting in an erratic behavoir from 1 to 53ms

I dont have my results up still from the one for the erratic ooma behavior, but below is the one that hop 11 is erratic.

As a consumer, if we use a service that has a high hop, is there anything we can do to have the server we are trying to connect to have a more direct route path? Cox says that there is nothing they can do, which I think sounds like hogwash, but I may be wrong.

Something is seriously mis-configured somewhere. That bounced all over the country.

I get 22 hops and 93 ms to that address from north of Philadelphia.
The trip from the east coast to the west coast was 1 hop on the level3 backbone.

Do you have any problems with not hearing the party your talking to or them not being able to hear you or anything strange going on, since you on the east coast same as myself?

I agree with Murphy ... there is something seriously wrong with the way the traffic is getting routed in your case. I get 13 hops, but I'm on the West Coast. Could you try a non-Cox connection, perhaps a neighbor or a friend who is willing to let you try it out?

I have 18 hops with just under 80ms from Atlanta.

Your 1st trace is absolutely crazy. You should call your isp and complain. The 2nd one with cox look ok though.

There are several different ways a router makes its path determinations. Depending on which protocol its been configured to use and if the normal path is up or down it can take as many as 30 hops to get to its destination. Routers can be set to use RIP or OSPF for example and it can make a big change on how its routes traffic.
