How to choose

Choose communication tools by workflow first. A voice platform is useful when calls, local numbers, CRM logging, call summaries, or support routing matter. A chat SDK is useful when communication lives inside your app. Scheduling and inbox tools are best when the bottleneck is operator time, not model quality.
