Natterbox

Natterbox helps you capture revenue from every conversation, with an AI contact centre built inside Salesforce. In G2’s Contact Center category, reviewers rate Natterbox 9.4 out of 10 for quality of support and 9.5 for ease of doing business. Natterbox runs its own global phone network and AI, offering an end-to-end solution for global businesses looking to capture or protect revenue through customer communications. With Natterbox, your team and AI agents handle calls, SMS, WhatsApp and chat at any hour, inbound and outbound. Voice AI agents take the routine calls, so you handle peaks without hiring for them. Everything is recorded, scored and written to Salesforce, so every conversation drives your competitive advantage. With one supplier, you have one team to call. Secret Escapes’ previous AI vendor stalled for over a year without going live, and Natterbox went live in six weeks. At Danone, AI agents answered 32,000+ calls in three months, and Secret Escapes, with 80+ agents, deflects 30% of calls with AI. SALESFORCE NATIVE CONTACT CENTRE Natterbox is for Salesforce teams with high call volumes. It is built natively in Salesforce, so nothing waits to sync, and you build routing and traditional or AI-powered IVR with clicks, not code. If you need voice in Salesforce, Natterbox supplies the calling, routing and AI agents. Danone, PRS for Music and Financial Lease see 100% of their calls in Salesforce, and Accquis logged 20% more sales opportunities. AI VOICE AGENTS AND CHATBOTS Voice AI agents answer routine calls in your brand’s voice. Callers say what they need, so there is no IVR menu to press through, and a call that needs a person reaches your team with a live summary. At We Buy Any Home, AI agents handle 81% of calls end to end. AI agents also make calls when a Salesforce record changes, such as a new lead or a renewal date, and write the result to the record. INBOUND AND OUTBOUND AI agents and your team follow the same routing rules, by skill and priority and on live Salesforce data, with callback from the queue. Your team can click to dial from any Salesforce record, show a local number, run an outbound dialler and send SMS and WhatsApp messages. QUALITY ASSURANCE, COACHING, AND COMPLIANCE AI Advisor scores 100% of calls against your own criteria and saves the score, transcript and summary on the Salesforce call record. Each agent gets coaching recommendations from their own calls. Transcripts give you speech analytics on every conversation, and competitor mentions, lead source and intent are written to the record. National Dental Care analyses 100% of calls and saves managers 20 hours a month on manual quality assurance. Call recording with pause and resume, compliance announcements and PCI card payments protect each call, and callers key in card details that the agent never hears. Christies Direct takes card payments with Natterbox PCI Payments.
