Most developers can write code. FreeSWITCH and Asterisk developers can build communication infrastructure that handles millions of calls reliably.
We Expertise in
FreeSWITCH and Asterisk have powered some of the world's most critical communication infrastructure. Banks use them. Telecom carriers depend on them. But building with these platforms requires engineers who understand technology and how to architect systems that remain stable under extreme load.
When you hire offshore FreeSWITCH developers or a dedicated Asterisk development team from us, you're getting engineers who have already solved the problems you're about to face. We work with telecom providers expanding their service offerings, SaaS companies adding communication features, enterprises modernizing legacy infrastructure, and startups building next-generation communication products.
FreeSWITCH is flexible, but only if you know how to use it. Our FreeSWITCH developers handle the complex dialplan logic, call routing, and architecture decisions that most developers struggle with.
Asterisk has powered communication systems for years because it is reliable when configured properly. Our Asterisk developers build systems that stay stable even when handling heavy call volume.
Build a PBX platform your business can actually depend on. We design these systems to handle the demands of modern business communication, with features your team needs and architecture.
Contact centers need to handle call volume while maintaining quality. We build customer engagement systems that do not break under pressure. Your support team gets the tools they need.
Combining FreeSWITCH or Asterisk infrastructure with AI creates systems that actually think. Your communication platform stops being just a call router and becomes something smarter.
Build SIP-based solutions that integrate seamlessly with your existing infrastructure without breaking anything. We handle SIP at the protocol level so your applications work reliably with carrier systems and existing telecom infrastructure.

End-to-end development for specific projects with defined scope and deliverables. Hire expert FreeSWITCH developers or Asterisk developers for controlled, predictable projects.
Best For
17+ Years
Engineering excellence
17+ years of experience in communication and telecom software development.
Solutions designed for scale, reliability, and performance.
Experience with SIP, VoIP, cloud telephony, and real-time communication technologies.
From discovery and architecture to deployment and ongoing support.
We start by learning what you are actually building and why it matters to your business. Your goals, your technical needs, and your growth plans shape the architecture.
When you hire dedicated FreeSWITCH developers or Asterisk developers from us, you are getting people who have already built what you are planning to build.
We work incrementally so you see progress happening. You get feedback opportunities, can request changes, and adjust direction as your business needs shift.
When it is time to go live, we handle deployment and keep monitoring your system. We optimize based on real performance and make sure everything stays stable.

Read moreAsterisk isn't something you learn on the side. Dialplan configuration, module development, keeping systems stable under heavy call volume — these require experience that only comes from having already built and run Asterisk systems in production. When you hire dedicated Asterisk developers from us, you're getting engineers who've already faced the problems you're about to run into and know exactly how to handle them.
Both power enterprise communication systems but solve different problems. Asterisk is the stronger choice for traditional PBX systems where stability and proven telephony features matter most. FreeSWITCH gives you more flexibility for modern multi-tenant architectures and high-scale platforms. When you hire Asterisk developers, you get deep PBX expertise. When you hire FreeSWITCH developers, you get a platform built for scale and flexibility.
Our offshore FreeSWITCH developers have built enterprise Cloud PBX systems, unified communications platforms, white-label SaaS products, AI-integrated contact centers, intelligent voice applications, modern softphones, and carrier-grade infrastructure. Whether it's an internal platform or a product you're taking to market, our FreeSWITCH development team has built something close to it already.
Our developers work across C, Lua, Python, JavaScript, Go, Java, React, Vue.js, Node.js, Django, FastAPI, PostgreSQL, MongoDB, AWS, Google Cloud, Azure, Docker, and Kubernetes. This means your communication platform gets built on a modern scalable stack.
Yes. Legacy telecom infrastructure is something our developers understand well and why certain decisions were made at the time. We assess what you have, identify what needs to change, and transition to a production-ready architecture without unnecessary disruption to systems that are currently running.
Typically one to two weeks. We handle the full process — understanding your requirements, selecting the right specialists, and integrating them into how your team works. From there they operate as an extension of your organization, not an external vendor you have to manage closely.
Three options. A dedicated FreeSWITCH or Asterisk developer for long-term focused ownership of your platform. A full offshore development team with developers, QA, and DevOps for larger or faster-moving projects. Project-based delivery for defined scope work — MVPs, platform modernization, and new product launches where you need clear timelines and deliverables.
Because our developers bring real telecom engineering experience, not general software development applied to a telecom problem. We own the full technical scope from architecture through deployment, build for enterprise scale from the start, and stay involved after launch. When you hire experienced Asterisk developers or offshore FreeSWITCH developers from us, you're working with people who have already built what you're planning to build.
