Standing Recurring Calls with Customers - Am I missing the value?

I've recently joined a new company and I'm being handed accounts from existing CSMs. I'm finding that a large number of CSMs at my new company have standing, recurring calls (weekly, bi-weekly, monthly) with customers that they are expecting me to take over. In the past, I've used recurring calls sparingly and for situations where I'm working through a project or escalated issue with a customer. The nature of these calls seems to be check-ins, pulse checks, and an opportunity for the customer to bring up support tickets that the customer wants an update on.

Am I wrong in thinking this approach is hard to scale and maybe missing the mark? Do you use regular standing calls with customers? If so, how do you ensure each call has value?

Thanks,
