Whether you’re researching SBCs for the first time, planning a SIP trunking migration, or looking for answers on a specific voice security challenge, these guides are here to help. Each series below breaks down the architecture, protocols, and real-world deployment decisions behind modern voice infrastructure.
Session Border Controller

How SBCs secure the network edge, enforce encryption between carrier and cloud, and handle SIP normalization across multi-vendor environments. Covers B2BUA architecture, topology hiding, Microsoft Teams Direct Routing, and cloud-native deployments.
SIP Trunking

The signaling layer that connects voice endpoints to carriers. Covers SIP header manipulation, the role of B2BUA versus proxy architectures, protocol normalization for multi-carrier interoperability, and troubleshooting the SIP messages that move calls through your network.
VoIP Security

Protecting voice traffic from the signaling layer to the media path. Covers STIR/SHAKEN caller authentication, FCC compliance mandates, SRTP and TLS encryption enforcement, DoS/DDoS mitigation at the SBC edge, and fraud detection strategies for service providers.
