Phone router question

We have a Cisco 2921 router. When they used the intercom extensively, it would reboot the router. We put a “huntstop” command for the dial-peer for the Intercom. The router is no longer rebooting, but we are seeing another issue. Here is a snippet of the log and can someone shed some light for me as to what is causing this?
