Cold outreach requires so much more than a VoIP number: Reps need to dial faster, retry intelligently, send multi-channel touches, and track outcomes with no manual work. While CallHippo is a great business phone system, most sales teams outgrow it when they try to scale outbound operations.
The following guide lists 10 powerful alternatives, ranking GrowOutly at #1 for high-volume cold calling, automated sequences, and connect-rate optimization.
