3. Highly cost-effective and scalable

Being a free and open-source telephony software, FreeSWITCH is highly cost-effective. It can reduce capital investment and operational costs of managed service providers (MSPs) to a large extent. Apart from providing high value for money, the software provides a scalable system for MSPs. The stable switching core and a strong interface enable MSPs to control the system. In addition to that, the software is cloud enabled. It can simplify complex deployment scenarios such as WebRTC, AI integration, and Advanced Micro Devices (AMD). By switching to FreeSWITCH, MSPs can optimize their tech stack and scale up (or scale down) their operations as and when required.

4. Extremely advanced

In the last 17 years, FreeSWITCH has undergone a huge transformation. All the subsequent versions contain critical security fixes and stability improvements.

Equipped with sophisticated features such as domain-based routing and partitioned settings, the open-source software enables MSPs to manage multiple clients efficiently.

7. Future-ready for MSPs’ growth

If they get the right support at the right time, then they can focus on their operations and provide the right services to their clients. If they don’t, then it can put an adverse impact on their operations. Whether it’s custom deployment assessment, deployment assistance, or priority bug fixes, MSPs that use FreeSWITCH can be assured of timely support from highly expert and experienced engineers.
