BENEFITS
Why bring VoIP calls into SleekFlow
Simplify daily operations
Calls, WhatsApp, and email in separate apps means separate logins, subscriptions, and more room for mistakes. Keep calls in the same SleekFlow inbox and wallet, one tool, one bill.
No missed follow-ups
A WhatsApp message that doesn't deliver can turn into a follow-up nobody makes. SleekFlow can send an SMS to the same number, and if there's still no reply, your agent can call without leaving the inbox.
Own your customer data
When agents take calls on personal numbers, customer context leaves with them. SleekFlow logs every call, WhatsApp thread, and SMS to one CRM record, so the relationship stays with your company, not one agent's phone.
Features
What's included
Smart routing
Send incoming calls to the right workspace, team, or agent automatically, instead of everyone racing for the same ringing line.
AI call summary
A short, auto-generated recap lands on the customer's timeline the moment a call ends, so nobody has to reconstruct what happened from memory.
AI transcript
Every call gets a full, searchable transcript alongside the recording. Useful for training, coaching, and settling disputes about what was actually agreed.
Call recording
Audio saves automatically next to the transcript and summary, a record for compliance and quality checks without a separate tool.

Frequently Asked Questions
Who is eligible for the US$100 call and SMS credit?
The credit is granted per company, not per user. Any company with an active SleekFlow subscription is eligible for the credit the first time it buys a new phone number for SMS and voice calls in SleekFlow.
Do the call and SMS credits expire?
Yes. You need to use them within three months of successfully connecting the channel and receiving the credits.
How much does SleekFlow Voice cost?
SleekFlow Voice pricing has three parts: your SleekFlow subscription plan, a monthly fee to host your local phone number, and a per-minute rate for incoming and outgoing calls. For full pricing details, see our SMS and voice pricing guide.
Which countries does SleekFlow support for local phone numbers?
Right now, SleekFlow supports local phone numbers in the United States, Hong Kong, and Malaysia. If you need a number in another country, contact SleekFlow support to check availability.
