How SleekFlow VoIP works

SleekFlow supports VoIP calls

Build on Twilio's global voice network

The telephony backbone trusted by thousands of Fortune 500 companies. Powering businesses calling at scale with carrier-grade uptime and quality.

Keep the number your customers know

If you're on Twilio, connect it to SleekFlow in a few clicks. If you're with another provider, talk to us. We'll review porting options for your number.

Run calls on the devices you already use

Plug in a headset and take calls from the SleekFlow web app or the mobile app on iOS and Android. Agents call from the business number, not their personal one.

Organize calls by brand, region, or business unit

Run separate workspaces for each, with their own numbers, agents, routing, and recordings. Admins control who can listen, transfer, or export.

Got questions about your setup?

We will show you SleekFlow Voice running, walk through your number and country options, and answer any specific to your business.
