Tailored to your needs

VoIP services for small, medium and large enterprises

System design, architecture and development

With many years of hands-on experience in software engineering and VoIP applications specifically, we can help you deliver state-of-the-art solutions to your open problems you may have. Among our services are design & implementation of:

  • SIP trunking
  • standard or custom SIP integrations with third party services and SIP providers like Twilio
  • advanced SIP elements, edge proxies, SBCs and SIP firewalls
  • WebRTC based SIP and gateways
  • media processing pipelines and SFU architectures
  • reverse engineering of VolP applications and APIs (bypassing TLS and certification pinning)

Our solutions are always fully tested with unit or integration automated tests and scalable according to your roadmap and future expectations.

Automated Testing

When building VoIP products with existing tools, unfortunately testing is something that we rarely see and most existing tools make it hard to build and automate such testing. This means that developers are afraid to touch code since those parts could easily break when employing new features and in general a lot of time and resources are spent developing new features. Some companies try to remend that problem by employing more time to QA, but even that has its own limits and most importantly it is not automated.

We have the expertise and the tools to set up complex testing scenarios that imitate your real world use cases that assert the expected behavior of your services and identify any breaking points. Load testing is another type of testing that we can deliver to help you evaluate the performance of your existing architecture and identify critical parts of your topology that need to be strengthened. All of our testing is completely automated, easily extensible in a developer friendly manner and can be integrated with any kind of CI/CD pipeline.

Requirements and feasibility review

VoIP and Real Time Communication applications & topologies need a lot of experience, expertise and knowledge to architect due to the sheer amount of protocols used and the real time nature of the data patterns that are employed. We can help you to assert the technical requirements based on your final product and conduct a feasibility review that will address and pinpoint all potential pitfalls of your architectural design, suggest changes, evaluate your risk exposure and assert security conformity.

Training

When building a new product, diving into VoIP architectures and protocols can be quite challenging for people coming from classic HTTP-related setup, where all services interaction take place on top of HTTP using friendly formats like JSON and in general network properties are usually hidden or abstracted under libraries and frameworks. If your team is not educated enough around the constraints and possibilities of the VoIP standards, protocols and architectures, you risk making wrong decisions not only in the tech side of things but also in the product level.

We offer dedicated training online or on-site for topics related to VoIP, SIP, WebRTC and media processing. We cover from ground up protocols like TCP, UDP, SCTP to transport protocols like SIP, SDP, (S)RTP, and (S)RTCP but also high level architectures using these protocols including server-side or client-side media relaying (ICE with STUN & TURN), SBCs architectures, security best practices and with common flows and patterns. Each training session can be adapted to the specific needs of the team.
