Call Center Hygiene / Best Practice

Hey peeps... I have a question for the group. Curious if your call centers are seeing a spike in attempted contact rate? If you seeing carriers flag your outbound calls more often with 'likely scam' more often?

Personally, we have seen a slight spike but not overwhelming (yet)... I do feel it's only going to grow...

Just curious what tactics you are using to help prevent the issue from rising.... Rotating DIDs is easy, registering numbers, what else have you found helpful to help improve contact rate?
