Great suggestions, guys. I set all the ports from the DSX-80 on a patch panel and tested the ringing problem right at the board. Problem persisted. I put two of the lines in a ring group. The rest are default to key ring. I will print and follow up with the suggestions listed here. I really appreciate your help. As familiar as I am with the programming and the systems themselves, I am a bit surprised by this problem. Will let everyone know the resolution. :bang: Al
