Alpire

Alpire is an AI customer-service phone tool that combines a cloud SIP phone system with voice AI agents, built for support and sales teams running inbound and outbound call operations. It puts extensions, queues, campaigns, supervision, recording, and website chatbots on one platform, so a team can handle calls, run outbound campaigns and callbacks, and monitor quality without stitching together separate tools. The voice AI side answers calls, transcribes conversations, scores call quality automatically, and offers live copilot assistance to human agents mid-call. Call flows are built in a drag-and-drop visual builder, or generated from a natural-language description of what the flow should do. Alpire connects out through a REST API, webhooks, an MCP server for AI assistants, and CRM integrations, and it is carrier-agnostic — you bring your own carrier via Twilio, Telnyx, or SIP trunks. For teams comparing AI call-center options on BestAIFor, Alpire is one of the best AI tools for adding voice agents on top of a phone system you already control. Note that AI usage is metered in credits per plan, so high call volumes can push you toward the larger tiers.
