Voice over Internet Protocol platforms route calls, messages, and video through data networks instead of traditional phone lines. Businesses use VoIP to consolidate communication channels, manage distributed teams, and reduce telephony costs without sacrificing call quality or reliability. Core features include number portability, call routing, voicemail transcription, and integration with CRM or helpdesk systems. Many services offer advanced analytics, call recording, and automated attendants to streamline inbound and outbound workflows. Security measures like end-to-end encryption and spam blocking are standard, supporting compliance and privacy requirements. VoIP tools make it possible to scale communications globally while maintaining control and oversight from a single dashboard.
