Have a customer with dual data centers with redundant SBCs and Verizon Trunks. When a response to an invite is a 480 (and some others including a 503) Verizon keeps sending invites to both data centers non stop. I have changed the 480 to a 404 to get the tidal wave to stop however I don't really want a network intercept stating the number is disconnected. Anyone else successfully work around this one? Discussions with Verizon to date have not been fruitful.

Changed to a 486 which at least for now fixes the issue and returns busy.
