Sideline Summary

Sideline is tailored for entrepreneurs and small businesses that need a professional second line without switching carriers. Unlike pure VoIP apps, Sideline routes calls through the user’s existing cellular network, preserving call clarity and reliability. The platform includes business-focused tools such as auto-replies, team number sharing, voicemail transcription, and integration with CRM systems. By keeping work and personal calls separate on the same device, Sideline helps maintain professionalism while reducing operational complexity.
