Cable Modem crashes while using GoToMeeting

Here is a weird one...my Cable Modem crashes when I use GoToMeeting and am using the phone at the same time. If I am hosting the meeting, dial in to the call, and begin running through a presentation or demo, my cable modem will completely reset. Boom. Lost phone. Lost internet. After a minute or two, it will reboot.

This may happen 3-4 times during over the course of an hour using GoToMeeting.

HELP! Anyone have this issue?
