I have a problem with jitter between my router in my house and the first gateway router to the Internet. I see the problem on VoIP calls using both Vonage and my corporate computer based VoIP solution, and video on demand on my non-DVR setup box. The VoIP blanks out and the video on demand stops for half a second every ~5 seconds.
I have a direct ethernet connection to my ONT and use the motorola NIM to bridge the coax network with the ethernet network. I used a Apple Time Capsule as my router to do DHCP and NAT service. Contrary to what many Verizon techs will tell you video on demand works just fine on a direct ethernet connection to the ONT with the motorola NIM bridge with using the 10.0.10.x subnet for DHCP. I have been such a happy FIOS user, I originally blamed Vonage as the cause of the problem. Vonage asked me to make the Vonage router my edge router to Verizon FIOS and have it do DHCP and NAT. I did, and after a few hours the problem came back. Got a new router from Vonage, problem still exists. Multiple firmware versions on the router, problem still exsits. Put back the Apple Time Machine as the edge router doing DHCP and NAT, problem still exists. After noticing the jitter on the video on demand and doing the following ping tests, I changed my opinion and now believe it is a network problem with the Verizon FIOS internet access and not a VoIP or router issue.
After calling Verizon, they dispatched a tech to my house and replaced my ONT but it has not solved the problem. The weird thing is when I unplug the router in my house the problem is solved for a few hours and then it comes back again. And of course anyone tries to troubleshoot the problem, they immediately ask me to unplug the router making the problem go away and then reappear after the customer support people declare the problem solved.
Here is the traceroute to a random host on the Internet:
$ traceroute www.verizon.com

Note that 96.241.212.1 is my gateway router, just 1 hop from my home router. Now I'll do a series of pings to that IP address.

--- 96.241.212.1 ping statistics ---
25 packets transmitted, 25 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 8.172/87.084/765.534/213.957 ms
Note the regular jitter up to 750 ms. Now I'll run the test over a longer period of time to show the summary:

round-trip min/avg/max/stddev = 7.607/112.393/1010.438/265.574 ms
Note that the jitter varies goes beyond a second in longer duration tests.
My field technician has not been able to get the right level of assistance on this. I'm posting this in an effort to get assistance from Verizon on the problem. It has been an outstanding problem for over two months. I cannot continue unplugging my router every three hours when working from home.
Thanks!
