The Problem

Why build an entire telephony infrastructure for your SaaS?

Do you want to add phone capabilities to your product? The challenge isn’t just about letting your users make calls. You also need to manage:

Phone numbers Incoming and outgoing calls Phone events Notifications Workflows WebPhone Integrations Call History And all the infrastructure behind it

Developing everything in-house can quickly tie up your technical teams on a project that isn’t your core business.

With Kavkom, you can integrate the telephony component into your product.

Before / After

Before

Telephony as an external tool

Your user must:

This creates friction.

After

Integrated Telephony

The path becomes:

Your SaaS→ Phone call→ Kavkom API→ Event→ Your SaaS

The experience remains centralized.

Less friction for the user.

More control over the product experience.
