V2 Voice API features guide


David Preo


Bandwidth has launched its new set of APIs for Voice! These APIs provide the same basic functionality for Voice that our V1 Voice APIs provided, but with 6-second billing and full integration into the Bandwidth Dashboard. This allows for simpler, easier use alongside Bandwidth’s advanced number management, messaging, and 911 services, and provides a smarter, more cost-effective way for enterprises to scale their API-driven voice communications.

New features

Downloadable BDR .CSV files  The Bandwidth Dashboard allows you to download rated Billing Detail Records (BDR) for your account.
6-second filling  Billing for each call is rounded to the nearest six seconds as opposed to the nearest minute in the V1 API. This more accurate billing can save customers anywhere from 20-50% depending on average call patterns and durations.
Application management  Managed within the Bandwidth Dashboard. Applications help direct call and messaging events, like take an incoming call and connect it with the right phone number or endpoint. You can learn how to create a Voice API in this support article.

Enhanced features (enhancements over V1 API)
