At its core, Dialpad Contact Center is the world's first Agentic AI contact center: AI agents that don't just transcribe or summarize, but reason, resolve, and act autonomously across the full customer journey. Instead of routing customers between disconnected tools, Dialpad Contact Center unifies voice, digital, and human agents in one platform, connecting the voice and data silos that have historically kept support teams siloed and reactive. Every interaction becomes part of a compounding intelligence layer. With 775M+ AI recaps and counting, Dialpad Contact Center turns each conversation into operational insight that improves resolution rates, agent productivity, and CX outcomes over time. That intelligence is continuously optimized, governed, and made visible across your organization through Dialpad's Guardian safety layer, ensuring secure, enterprise-grade AI operations at scale. Dialpad Contact Center is built to resolve up to 80% of issues autonomously, reducing operational complexity while giving human agents the context they need for what still requires a human touch. People stay at the core; intelligence sits at the edge, ready to act the moment it's needed. Rather than asking enterprises to take autonomy on faith, Dialpad Contact Center is validated through Dialpad's Proving Ground, so teams can confirm ROI and reliability before committing at scale — a modern alternative to legacy, static bots and fragmented support stacks. 1,607 Ratings Visit Website Intermedia Unite Intermedia Unite® brings business communications, collaboration, and customer engagement into one easy-to-use platform—keeping teams connected, productive, and responsive from anywhere.

AI voice agents call, qualify, nurture and live-transfer leads around the clock, answer inbound calls, and book appointments, while every outcome writes back to your CRM. You don't assemble the stack yourself. Bigly writes your call scripts with Claude, ChatGPT and other leading LLMs, then tests script versions against each other on live traffic and keeps the one that converts best. Phone numbers, carrier registration, more than 200 whitelisted lines with local presence, spam monitoring, call routing and campaign setup are handled for you before the first dial. Each call is checked against consent, suppression lists, known TCPA litigants and state and federal calling rules, including quiet hours, before it is placed. Reporting is built around the result you pay for. The dashboard tracks success rate per lead, cost per transfer and cost per human contact, plus a dial-to-transfer funnel that shows where calls drop off: no answer, DNC request, failed qualification, or a transfer the agent never picked up. Leads can arrive in real time from API vendors or as uploaded lists, and every source is ranked by success rate and cost, so you can see which lead vendors pay off. An hour-by-hour view shows when your leads actually convert. The Bigly Sales MCP server lets you run the account by asking Claude or ChatGPT: add leads to an active campaign, check pacing and minute usage, pull call summaries and transcripts, or find out who picked up today and wants a demo. Common uses include aged and dead lead reactivation, speed-to-lead follow-up on web and vendor leads, appointment setting, inbound answering and overflow, and warm transfers to licensed agents in insurance, lending, home services, legal, auto and political fundraising. Integrations include HubSpot, Salesforce, Zoho CRM, Pipedrive, GoHighLevel, Close, Follow Up Boss, Keap, monday CRM, Freshsales, ActiveCampaign and Microsoft Dynamics 365, plus an API for real-time lead posting. Plans start at $99 a month for 500 minutes, and Hunter, Closer and Rainmaker add a dedicated account manager who watches results and tunes your campaigns. New customers start with a free 30-minute AI calling setup ($3,000 value): the team builds your calling system live, shows the MCP and runs a test call. 8 Ratings Visit Website Zoom Phone Zoom Phone is an AI-powered cloud-based business phone system that provides voice calling, messaging, and unified communications through a Voice over Internet Protocol (VoIP) platform.
