Sip Failing

I have a system that sip communications fail on at least once a week. I can still log into the gui and ssh, but internal sip phones and sip trunks do not work. I am using a Xorcom xr2000 with Freepbx, Elastix 1.6.2-27 and Asterisk 1.4.36, I am using Cbeyond for my sip trunk and it is behind Sonicwall TZ 210.

This is the 30 minutes before the reboot
