What is a SoftSwitch?

A SoftSwitch (Software Switch) is a software platform that performs the switching and routing of telephone calls on IP-based telecommunications networks (VoIP). Unlike traditional hardware-based switches, a SoftSwitch is a flexible, scalable, and lower-cost solution.

How does it work?

The SoftSwitch acts as the "brain" of the telephony network, being responsible for:

• Signaling: Controls the establishment, maintenance, and termination of calls
• Routing: Determines the best path for each call based on business rules
• Mediation: Collects and processes call data for billing (CDRs)
• Interoperability: Connects different networks and protocols (SIP, H.323, ISDN)

SoftSwitch Classes

Class 4 (Transit)

Responsible for routing calls between operators and handling large traffic volumes. Main features:

1. LCR (Least Cost Routing) routing
2. Media transcoding
3. CDR generation for interconnection
4. Multi-protocol support

Class 5 (Access)

Manages end-subscriber calls, offering features such as:

1. Caller ID
2. Call waiting
3. Call transfer
4. Voicemail

Why does your operator need a SoftSwitch?

1. Scalability - Supports thousands of simultaneous calls
2. Intelligent routing - LCR (Least Cost Routing) to optimize costs
3. Compliance - Automatic generation of DETRAF and CDRs
4. Integration - APIs to connect with BSS, SBC, and other systems

SipPulse SoftSwitch

The SipPulse SoftSwitch is a Class 4/5 platform developed specifically for the Latin American market, with native support for:

• Anatel regulations (DETRAF, STFC, SCM)
• Integration with SBCs for border security
• Real-time monitoring dashboard
• REST APIs for integration with legacy systems

Conclusion

The SoftSwitch is the fundamental piece of infrastructure for any modern telecommunications operator. With the growing migration from legacy networks to IP, investing in a robust and reliable SoftSwitch is essential to maintain competitiveness in the market.
