UTC Bilişim
// PBX integration partner

Your partner for PBX integration projects.

We help resellers, MSPs and businesses connect 3CX, Yeastar and Asterisk to their CRM, IVR, dialers, reporting and AI voice agents. We start with what you need, then build the right solution, under your brand if you prefer.

// Platforms

VoIP is our craft. These three we know best.

We have years of hands-on experience with these three platforms, from the API to the dialplan. But we are not tied to them: if another tool fits your project better, we build with that. We start by understanding what you need, then deliver the right solution.

We also work with FreePBX, FreeSWITCH and ASTPP when a project calls for them.

// How we work

From requirement to go-live.

  1. 1

    Understand the requirement

    We talk through what you want the call to do and what your systems look like. Plain language, no sales script.

  2. 2

    Scope and fixed quote

    You get a written scope and a fixed price before any build starts.

  3. 3

    Build and test

    We build against the platform's API or dialplan and test it with you before it goes live.

  4. 4

    Go-live and support

    We roll it out, hand over the documentation and stay available afterwards.

// Questions

Quick answers.

Which PBX platforms do you work with?

Mainly 3CX, Yeastar and Asterisk (including FreePBX). If your project needs another tool, we will tell you honestly whether we can build it.

Can you deliver under our brand?

Yes. Many of our projects are white-label work for resellers and MSPs. You stay the customer's first contact.

How is a project priced?

We give you a written scope and a fixed price before the build starts, so there are no surprises.

Do you support the solution after go-live?

Yes. Support after go-live is part of how we work, and every delivery comes with documentation.
