Calilio

Calilio is a cloud-based business phone system and call center software built for sales, support, and remote teams. It helps businesses move away from traditional desk phones and on-site PBX hardware by enabling teams to make and receive calls over the internet using VoIP technology from desktop, web browser, iOS, and Android devices. With Calilio, businesses can buy or port virtual phone numbers, including local, mobile, and toll-free numbers, from 100+ countries and manage customer communications from a shared workspace. Teams can handle calls, SMS, MMS, voicemail, notes, tags, recordings, and call history without switching between disconnected tools. Calilio supports inbound call management with features such as IVR, call forwarding, business hours, voicemail, call transfer, number sharing, and call routing. Its Ring Strategy allows businesses to define how incoming calls are distributed across team members based on availability, team structure, and call-handling requirements, helping teams manage call flow more effectively. For outbound sales and customer outreach, Calilio offers a power dialer, contact import, campaign setup, custom caller ID, click-to-call, call disposition, notes, tags, recordings, and analytics. Teams can also use Bulk SMS to send messages to multiple contacts for announcements, reminders, follow-ups, campaigns, and other customer communications directly from the same business communication platform. Calilio also introduces an AI Voice Agent that uses artificial intelligence to support customer conversations and automate parts of call handling. It can assist businesses with sales, customer support, and call center workflows while helping reduce manual call-handling effort and improve response speed. The Standard plan includes up to 10 minutes of AI Voice Agent usage per user per month, while the Premium plan includes up to 100 minutes per user per month. Calilio integrates with KudosCRM & HubSpot to connect business calling with customer relationship management. Call activity can be connected with customer records, helping sales and support teams keep conversations, customer information, and follow-up activities in context. This reduces the need to manage calling activity separately and gives teams a clearer view of customer interactions throughout the sales and support process. Managers and supervisors can use live call monitoring, call whispering, call barge-in, call recording, and analytics to review team performance and support agents during important conversations. Calilio’s AI-powered call reports help teams review conversations faster with call transcription, summaries, sentiment analysis, reason for call, and call conclusion. Available across Web, iOS, and Android, Calilio gives teams the flexibility to manage business communication from desktops, browsers, and mobile devices. Users can make and receive calls, access messages, manage virtual numbers, and review call activity from the device that best fits their workflow.

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.
