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.
