In today’s digital-first world, telcos are under constant pressure to innovate while reducing operational costs. Yet, many service providers still rely heavily on legacy SS7 infrastructure, a system that has been the backbone of call control and value-added services for decades. The common belief is that these traditional networks are outdated, costly to maintain, and incompatible with modern IP-based systems. But here’s the truth, your legacy network isn’t dead. With a SIGTRAN gateway, it can be reborn into a highly efficient, scalable, and future-ready platform.
Despite the surge of 5G, cloud-native deployments, and all-IP transformations, SS7 remains deeply embedded in global telecom. It enables critical services such as SMS, call routing, mobile authentication, and roaming. Operators can’t simply “switch off” these systems without risking service continuity and customer trust (GSMA Mobile Economy).
However, traditional SS7 networks present challenges:
This is where SIGTRAN (SS7 over IP) comes in. By transporting SS7 signals over cost-effective IP networks, it bridges the gap between legacy systems and next-gen services, ensuring telcos maximize existing infrastructure investments while embracing innovation.
The SIGTRAN gateway from hSenid Mobile is more than just a bridge, it’s a catalyst for digital transformation. Unlike hardware-based stacks that lock operators into expensive proprietary ecosystems, hSenid’s software-based solution is built for flexibility, scalability, and cost-efficiency.

Examples of direct API calls include:
The telecom industry is shifting toward digital ecosystems, and legacy systems must evolve to stay relevant. By adopting a SIGTRAN gateway, operators can:
In essence, SIGTRAN isn’t just about extending the life of SS7, it’s about giving it new purpose in a digital-first era.
Legacy doesn’t mean obsolete. With the right solution, it means resilient, adaptable, and future-ready. The SIGTRAN gateway by hSenid Mobile ensures that operators can continue to leverage their SS7 investments while opening doors to innovation, scalability, and cost savings.
Instead of viewing legacy infrastructure as a burden, see it as an untapped asset waiting to be transformed. The journey toward modernization doesn’t have to be disruptive or expensive, it can be strategic, seamless, and rewarding.

1. Why Legacy Networks Still Matter
Despite the surge of 5G, cloud-native deployments, and all-IP transformations, SS7 remains deeply embedded in global telecom. It enables critical services such as SMS, call routing, mobile authentication, and roaming. Operators can’t simply “switch off” these systems without risking service continuity and customer trust (GSMA Mobile Economy).
However, traditional SS7 networks present challenges:
- High maintenance costs due to proprietary hardware.
- Limited flexibility in integrating with modern applications.
- Scalability issues when demand spikes.
This is where SIGTRAN (SS7 over IP) comes in. By transporting SS7 signals over cost-effective IP networks, it bridges the gap between legacy systems and next-gen services, ensuring telcos maximize existing infrastructure investments while embracing innovation.
