I have an RCA DCM425C modem (provided by Comcast) which reboots frequently (several times an hour) when I try and use my IP Phone (Cisco 7960).
My laptop (IBM T42 w/Windows XP) and IP Phone are both connected to a Cisco 871 router which tunnels everything over a VPN connection back to my employer.
The only difference I can think of between IP Phone traffic and other traffic is that the IP Phone packets have QoS bits set on them.
Anyone heard of problems sending packets with QoS over this modem?
I've called Comcast and they won't do anything unless they see it fail with my PC directly connected. :-(
