VOIP
Paying Someone Else's VoIP Provider While Your Own Customers Could Be Paying You?
Businesses and telecom providers across the US routinely resell someone else’s calling app instead of launching their own — leaving margin and brand control on the table. Krify Phone is a white-label VoIP calling app built on SIP, ready for you to launch under your own brand with voice, video, and messaging already working.
Overview — Krify Phone
A ready-to-launch white-label VoIP calling app built for US businesses, telecom providers, startups, and entrepreneurs who want their own branded calling platform without building one from scratch.
SIP-to-SIP voice and video calling, plus app-to-PSTN calls to landlines and mobiles worldwide
Instant messaging with image, video, and media sharing
One-to-one and group chat with full chat history
Real-time push notifications for calls, messages, and updates
Credit and balance management with call rates shown before every call
Cross-platform support across Android, iOS, Windows, and Mac
Who This Is For
Businesses reselling a generic VoIP app instead of running their own hit the same limits: no branding, no control over margins, and no platform to build on.
- Reselling someone else's calling app means losing both margin and brand presence
- No unified platform for voice, video, and messaging under your own name
- Limited visibility into usage, credit balances, and call activity across your user base
- Scaling a white-label VoIP business is hard without a platform built for growth
- Building a SIP-based calling app from scratch means months of development before the first call connects
Fits US businesses, telecom providers, startups, and entrepreneurs ready to launch a branded VoIP calling service instead of reselling someone else’s.
