Calling is Seamless.AI's built-in dialing and call-management workflow for outbound sales outreach.
Calling provides click-to-call VoIP dialing, bulk Call All sequencing, and automatic call logging with dispositions, so reps can work phone lists without leaving the provider's platform. Compliance controls cover TCPA calling windows, do-not-call management, caller ID, and local presence dialing.
Call recordings, notes, and analytics are stored in a shared activity dashboard, and the workflow connects with the provider's email, task, and list-building products to run multi-channel outreach from one workspace.
