CallHippo vs Slingshot VoIP
Both stand on business phone systems. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose CallHippo for a business phone system with multiple numbers, routing, voicemail transcription and CRM connections. Starter is aimed at small businesses, while Professional and Ultimate add higher-tier calling and operational features. Look elsewhere if your calling needs fall outside the stated US and Canada limits or you need to keep using the service beyond Basic’s six-month free period without upgrading.
