Experts Supporting Asterisk Soft-Switches

Decades of Experience

With almost two decades of experience in the ever-evolving world of telecommunications, GEN has been at the forefront of Asterisk development and implementation since its early days. Our journey began with Asterisk 1.6, released in 2008, and we've grown alongside this remarkable platform through its numerous iterations. Asterisk, conceived by Mark Spencer in 1999, revolutionised the telephony landscape by offering a free, open-source solution that could rival proprietary systems costing tens of thousands of pounds.


Throughout its history, Asterisk has consistently proven itself as the most versatile and robust open-source telephony platform available. Its flexibility allows for seamless integration with both legacy systems and cutting-edge technologies, making it an ideal choice for businesses of all sizes. From small startups to large enterprises, Asterisk's scalability and customisability have made it the go-to solution for companies seeking to break free from the limitations and high costs of traditional PBX systems.


At GEN, we've harnessed the power of Asterisk to build bespoke solutions that cater to the unique needs of our clients. Our comprehensive support and management services are backed by years of hands-on experience, ensuring that your Asterisk-based system not only meets but exceeds your telecommunications requirements. Whether you're looking to implement advanced IVR systems, integrate with CRM platforms, or deploy complex call routing strategies, our expertise in Asterisk makes it all possible—and remarkably cost-effective.

Open Source & Rock Solid

Asterisk's open-source nature is one of its greatest strengths. This transparency allows for continuous improvement, rigorous security auditing, and rapid innovation driven by a global community of developers and users. Unlike proprietary systems, where you're at the mercy of a single vendor's roadmap, Asterisk empowers businesses to adapt and extend their telephony systems to meet specific needs. This flexibility, combined with the absence of licensing fees, translates to significant cost savings and unparalleled customisation options for organisations of all sizes.


When it comes to reliability, Asterisk stands head and shoulders above the competition. Its rock-solid architecture, honed over two decades of development and real-world deployment, ensures exceptional stability. In fact, many of our clients report years of uninterrupted service without a single crash or failure. This robustness is further enhanced by Asterisk's efficient resource utilisation and ability to handle high call volumes with ease. Whether you're running a small business or a large call centre, Asterisk provides the dependable foundation necessary for mission-critical communications.
