Our solution has been designed and implemented with an architecture that allows for horizontal scaling and meets industry standard requirements for a service-level agreement (SLA) of 99,999% uptime, ensuring high availability and reliability of the platform.

With our solution, the telecom company was able to easily scale its communications platform as its business grew, without having to worry about investing in costly infrastructure or hardware.


Our cloud unified communications solution provided the telecom company with a highly reliable platform, with built-in redundancy and failover mechanisms that ensured maximum uptime and minimal service disruptions.


Our solution was designed with ease of maintenance in mind, with built-in monitoring and diagnostic tools that allow for easy troubleshooting and issue resolution.


Our solution provided the telecom company with the flexibility to easily add or modify features as needed, without having to worry about compatibility issues or complex integration requirements.


By using our cloud unified communications solution, the telecom company was able to significantly reduce their infrastructure and maintenance costs, while still providing a high-quality communications service to their customers.


Key Benefits of the Cloud Unified Communications Solution

Results of Integrating a Unified Communications Solutions

The telecom company was able to deploy cloud-based unified communications quickly and with no disruption of service. This enabled the telecom company to keep its customers satisfied and increase its customer base.

«We are beyond thrilled with the outstanding results we experienced by partnering with byVoice for our Cloud Unified Communications Solution. From the very first interaction, their team showcased unparalleled expertise and professionalism. They expertly guided us through a smooth transition to a modular architecture, enabling us to scale our system and incorporate crucial features such as call routing, IVR, voicemail, and more. Their SaaS platform proved to be remarkably flexible, reliable, and cost-effective, flawlessly fitting our unique business requirements.

After implementing a Softswitch, signaling servers, media servers, and other components, we focused on conducting a phased migration to the new platform in the final stage.

After implementing a Softswitch, signaling servers, media servers, and other components, we focused on conducting a phased migration to the new platform in the final stage.

Step taken:

This strategic approach allowed us to ensure a smooth transition for the client, while also providing us with the flexibility to add or modify features as needed.

Why was it taken?





Session Border Controller


Conference server






Programming languages




The unified communications system had a significant impact on the telecom company. Softswitch enabled seamless routing of calls, signaling servers ensured smooth communication sessions, and media servers improved communication quality. Application servers gave a competitive advantage, SBC controllers secured communication sessions, and conference servers enhanced collaboration.

Why was it taken?


It was implemented to connect various communication devices and networks, enabling the seamless routing of calls and other media between endpoints.

Signaling servers

We deployed signaling servers to manage the signaling of communication sessions between different endpoints, ensuring smooth and efficient communication.

Media servers

They were integrated to process and manage various types of media, including voice and video streams, ensuring high-quality communication.

Application servers

We integrated application servers to enable the delivery of value-added services such as call routing, IVR, voicemail, and more, providing the telecommunications company with a competitive advantage.

SBC controllers

We integrated OpenSIPS to secure communication sessions by managing and enforcing security policies.

Video conference servers

They were set up based on a third-party solution to enable high-quality video conferencing between multiple participants, enhancing collaboration and productivity.

Audio conference servers

We deployed FreeSWITCH-based audio conference servers to enable seamless audio conferencing between multiple participants, ensuring effective collaboration.

Call recordings processing pipeline

It was implemented to capture and process all communication sessions, providing valuable insights and facilitating compliance with regulatory requirements.

We integrated a web control panel to enable the telecommunications company to manage and monitor its communication system, providing real-time insights and control.

Media storage

We provided it to enable the long-term storage and retrieval of media streams, ensuring easy access and retrieval of communication data. This included audio recordings of conversations, conferences, and audio fragments for IVR, among others.

Media Gateway

Its implementation to support SS7 and ISDN connections involved integrating a device that converts SS7 signaling to VoIP signaling. This conversion enabled traditional circuit-switched telephone networks to connect with modern IP-based networks.

In this stage, we focused on implementing the core features of our unified communications system. These features included:



We implemented a modular architecture that eliminated the dependence of the business logic on interaction with specific equipment and the billing system.

We also conducted rigorous load and stress tests to ensure the system’s performance and stability.

Step taken:

By highlighting the HAL (hardware abstraction level), we were able to achieve greater flexibility and agility in our system’s development and maintenance. This strategic move was needed to result in a faster and more efficient development process, while still maintaining the same high levels of reliability and scalability.

Why was it taken?

What are unified communications?

It is a comprehensive platform that integrates various communication channels, including voice, video, text, and fax, into a single cohesive system. The primary objective of this platform is to deliver a unified user experience across multiple devices and systems, enabling seamless communication and collaboration across all channels.

This technology is designed to streamline communication processes and enhance efficiency in the workplace. By providing a single, centralized platform for all communication channels, unified communications eliminate the need for multiple systems and applications, simplifying the communication process and improving productivity.

In this case, our team was tasked with developing a unified communications solution from the ground up on a new communications platform.

Cloud Unified Communications Solution

The customer needed a seamless migration to a new architecture without disruptions for their end-users. A custom solution based on Softswitch architecture was chosen after a thorough evaluation for its ability to meet specific requirements and ensure a smooth transition with minimal disruption.

Company Challenge

The 30% annual traffic growth rate resulted in a high cost for businesses with around 100 boards, each costing $15,000. The following year, this led to an estimated expense of $450,000.


Older CT boards took up a lot of space in server chassis and added to the expenses of renting racks in data centers. Also, the EDL status of CG6565 boards created problems for the company.​


Their clients complained about hearing background noise and other people’s discussions during conversations. This raised security and privacy concerns about the communication system.



Older software was written in a procedural style and took on the form of a monolithic application. It posed challenges in terms of maintainability and the possibility of further development.

Telecommunications Company Challenge

Our client used to have an outdated version of their platform, which was built on computer telephony (CT) boards. The company had been struggling for some time with the following issues:


Our client is a prominent telecom company with a longstanding presence in the regional cloud PBX (private branch exchange) market. They sought out our expertise to help them replace their CT boards with an innovative telecommunications software solution.

They solicited our assistance in modernizing their prepaid card service platform, which they had been utilizing in a manner incongruous with their objective of providing Cloud PBX services. With our expertise in developing software solutions for cloud telephony and cloud contact centers, we were challenged to provide them with the necessary services to build a new platform that could meet their goals.
