Session Border Controller
The SBC works as a B2BUA: signaling and media terminate at the edge, then are rebuilt inward. PBX topology stays hidden, malformed SIP does not pass through, and sessions obey admission control.
SIP trunks, carrier connectivity, and Session Border Controller.
Connect carriers and SIP trunks to Praytec Dialcortex through an SBC — for security, remote registration, interoperability, and more stable call quality.

Failover
Remote SIP without the pain
Register IP phones, softphones, and branch endpoints without brittle port-forwarding — remote paths are managed through the SBC.
Trunk interoperability
Normalize signaling across providers and systems so SIP trunks from different carriers stay reliably connected.
Routing & resilience
Load-balance across trunks/gateways, apply routing rules, and fail over when one network path is disrupted.
Encryption & protection
TLS for signaling, SRTP for media, plus policies that reduce toll-fraud and voice-layer attack risk.
Foundation for PBX & AI
The Connect layer underpins Cloud PBX, contact center, Voice API, and AI voice agents in Praytec Dialcortex.
Why it matters
SBC secures the voice edge: remote SIP, normalization, and traffic protection to carriers.
