Hi Jeff, Thanks for the reply. My knee jerk reaction when I first saw your post is that you may have had multiple PRIs across multiple TDM groups. I'm glad you've dug into this a bit. By default, inter B-channel transfer (hair pinning) is not allowed via AOS switchboard. However, I was running on a number of assumptions. Best, Mark
