Jitter and Packet Loss in Oakland, CA
We are having trouble using VOIP on our Comcast Business service. Although our speed is more than sufficient, we have serious quality of service issues. As shown on the graph below, our VOIP provider has determined that our connection is fine until the last 4 hops (all passing through Comcast equipment), where we have packet loss and packet jitter (erratic transmission/reception). Who should I contact so that someone will check and fix the equipment servicing us on these last 4 hops?
Thank you in advance,

The problem is with 220.127.116.11
That is your hardware:
Comcast IP Services, L.L.C. SFBA-CDM-15 (NET-96-120-88-0-1) 18.104.22.168 - 22.214.171.124
Comcast IP Services, L.L.C. CABLE-1 (NET-96-64-0-0-1) 126.96.36.199 - 188.8.131.52
This is what it looks like from the customer side:
64 bytes from 184.108.40.206: icmp_seq=45 ttl=254 time=10.3 ms
64 bytes from 220.127.116.11: icmp_seq=46 ttl=254 time=2008 ms
64 bytes from 18.104.22.168: icmp_seq=47 ttl=254 time=1009 ms
64 bytes from 22.214.171.124: icmp_seq=48 ttl=254 time=10.1 ms
This has been happening for over two days. Pinging 126.96.36.199, for example, does not show the packet loss and delay, so it's definitely whatever my next hop is from my cable modem. Please update this thread with a status.
