SBC USE CASES
Real Deployment Scenarios for ProSBC
From carrier peering to fraud protection, these are the ways operators and enterprises deploy ProSBC in production.
USE CASE
Access SBC
An access SBC facilitates and protects user access to hosted applications, including IP-PBX, contact center, conferencing, and unified communications platforms. It handles NAT traversal, registration forwarding, and security for thousands of remote subscribers connecting through the public internet.
USE CASE
Peering
SBC peering interconnects two service provider voice networks at the core, securing the boundary, mediating SIP differences, managing traffic routing and capacity, and producing call detail records for settlement between carriers.
USE CASE
Enterprise SIP Trunking
Enterprise SIP trunking connects one phone system to multiple carriers for toll-free, DID, and international service. The SBC normalizes each carrier’s SIP, routes and fails over calls across trunks, and protects the IP-PBX from every carrier-facing path.
USE CASE
Cloud Comms Trunking
Cloud communications trunking connects UCaaS, CCaaS, and CPaaS platforms to their carriers through an SBC that manages routing, SIP normalization, and protection across multiple operators so the platform sees one consistent connection.
USE CASE
Cloud Comms Access Security
Cloud communications access security uses an SBC to encrypt and protect remote user connections to UCaaS and SaaS voice platforms, handling SIP over TLS, SRTP media encryption, and NAT traversal on the platform’s behalf.
USE CASE
CPaaS Enablement
CPaaS enablement gives application developers a cloud SBC to connect their own carriers, with SIP normalization and media bypass that keeps cloud egress costs down while the SBC handles carrier connectivity and interoperability.
USE CASE
STIR/SHAKEN
In the STIR/SHAKEN use case, the SBC acts as the point where outbound calls are authenticated (signed) and inbound calls are verified, integrating with a signing and verification service to attach and check the cryptographic identity token.
USE CASE
Real-Time Fraud Protection
Real-time fraud protection scores every call during setup by integrating the SBC with a fraud-scoring service. The SBC allows, blocks, or flags each call before it connects and before fraud can generate a bill.
USE CASE
TDoS Protection
TDoS protection uses an SBC together with a reputation or analytics service to evaluate flooding calls as they arrive. The SBC blocks, redirects, or allows each call based on its risk, screening out call floods before they overwhelm agents.
USE CASE
SBC Redundancy
SBC redundancy builds backup paths across the voice network so the failure of any single component — a trunk provider, operator, softswitch, or SBC — reroutes traffic automatically instead of dropping calls.
USE CASE
TDM to SIP Migration
TDM to SIP migration moves voice services off legacy TDM switches onto a cloud softswitch. The SBC sits between the legacy customer network and the cloud, bridging the two during a staged migration with SIP survivability on the roadmap.
USE CASE
Intelligent Edge
The intelligent edge pushes SBC routing, traffic management, and filtering out to the customer premises rather than handling everything at the network core, giving each site local control as a virtualized SBC on universal CPE.
