I'm having a weird issue this morning. We have a CS1000 5.5 with 5 LD PRIs and 2 local PRIs. We are getting very intermittent static on calls and calls being dropped on both incoming and outgoing calls- local and long distance. I've checked the PRIs and they're clean (no errors). There are one way speech issues as well, but not on every call. These are all digital phones, but on various cards throughout the system. I've put in a ticket to my maintenance vendor, but I thought I'd post it here to see if anyone had any ideas.
