What is STIR/SHAKEN?

To prevent Caller ID spoofing, the Federal Communications Commission (FCC) and Canadian RTC are mandating the implementation of a new industry standard called STIR/SHAKEN. STIR/SHAKEN establishes a framework that strengthens caller identity security and helps unmask spoofed calls. Many VoIP service providers in the United States are required to deploy STIR/SHAKEN no later than June 30, 2021.

Blocs SIP Routing

Blocs Session Initiation Protocol routing refers to the process of determining the path that SIP messages (signals) take through a network to establish and manage real-time communication sessions. SIP is a protocol commonly used for setting up audio and video calls, instant messaging, and other communication sessions over IP networks.

Blocs SIP routing involves making decisions about how to route SIP messages from one endpoint to another to establish a communication session. This routing can occur within a local network, across different networks, or even between different service providers. The goal of SIP routing is to ensure that the messages reach the intended recipient efficiently and reliably.

Key concepts in Blocs SIP routing include

Icon1

Proxy Servers:

Proxy servers are intermediaries that handle SIP messages on behalf of endpoints.

Icon1

Location Services

Blocs SIP routing often involves looking up the current location or IP address of the recipient of the communication.

Icon1

Topology Hiding

Blocs SIP routing can involve hiding the network topology from outside users for security reasons.

Icon1

Load Balancing

In larger networks or service provider environments, load balancing mechanisms might be used to distribute SIP traffic across multiple servers or resources to ensure efficient utilization of resources.
