Secure Communications

between Mobile and Desktop Phones Overview


How it Works

KoolSpan’s TrustBridge provides a secure link between TrustCall running on the open public infrastructure and the existing desk phones on the closed private voice network. TrustBridge is installed at the edge of the corporate network; bridging secure VoIP calls in from the Internet to the internal PBX. As part of the process of connecting the secure TrustCall devices with the enterprise network, the TrustBridge translates or “bridges” the mobile- optimized and proprietary secure TrustCall VoIP protocol to the enterprise standard SIP/RTP.

Product Features

TrustBridge supports secure communications between TrustCall enabled Android and iPhone devices and SIP based PBX desktop phones and includes the following features:

  • Man-in-the-middle protection
  • Dual-tone multi-frequency signaling (DTMF) keypad
  • Opus, G.711 a-law and mu-law audio codecs
  • Automatic updates
