прекратить обзвон абонентов commun.

[Alex16]

- ФАСом могло быть вынесено предписание об устранении нарушения антимонопольного законодательства, в том числе прекратить обзвон абонентов, плюс привлечь к административной ответственности - 0,15% оборотный штаф

(я так понял, 0,15% от оборота)

Заранее премного благодарен.

cease and desist / discontinue/stop cold calls (если только речь именно о незваных звонках (:
или, в конце концов, почему бы не самое очевидное stop calling customers?

[silly.wizard]

stop (calling / calls to) customers +1

can these still be called "cold calls"? i thought this is only used with prospective customers, not with existing ones

oбзвон - (a) call-down

An initial marketing campaign designed to garner 10 appointments might include 100 emails sent to a targeted list of prospects, followed closely by 100 postcards. The telemarketer will then follow up with 100 call-downs to gauge interest and set some appointments.

[Tamerlane]

Conduct a "call down" of customers who no longer buy from your company and ask them what led to their decision to do business elsewhere. The information these past customers provide you with can help you identify trends that have the potential to drive business away, such as poor customer service, quality of product, price, locations, etc. You can use this information to better your business.
