SIP Signaling and Media Conversion
The M5 Media Gateway provides the necessary media conversion and SIP signaling control for integrating analog devices into SIP-based VoIP infrastructure. This process is achieved by converting analog audio signals to VoIP format and utilizing SIP-based routing.
SIP Signaling Control
- Call Setup: Devices establish and route calls via the SIP protocol.
- Authentication: SIP-based authentication is used for user identity verification and secure session management.
- Session Management: SIP is used to initiate, manage, and terminate sessions.
- Security: The M5 Media Gateway provides edge-of-SIP-network protection against unauthorized calls and fraud risks.
Media Conversion
- Analog Audio Signals: Analog audio signals are converted to VoIP format and transmitted over the IP network.
- Media Coding: RTP or SRTP protocols ensure the secure and efficient transmission of audio data.
Long Loop Support
The M5 Media Gateway supports connections for long-distance analog terminals (e.g., indoor buildings, factories, tunnels). This feature enables the planning of long-distance connections between analog terminals and gateways or PBXs, as well as signal strength preservation.
Long Loop Features
- Copper Cable: Analog terminals can be connected via long-distance copper cables.
- Signal Preservation (Impedance, Voltage): Proper planning is required to maintain signal strength and long-distance connections for analog terminals.
- Connection Environment: Long-distance connections for analog terminals must be planned according to the environment (e.g., buildings, tunnels) and cable length.
Security Features
The M5 Media Gateway provides protection against unauthorized calls and fraud risks at the edge of the SIP network. The device operates securely with SIP-based authentication and security mechanisms.
Security Features
- SIP Authentication: User authorization and identity verification enhance SIP-based network security.
- Unauthorized Calls: The M5 Media Gateway provides protection against unauthorized calls.
- Secure Network Topology: The device creates a secure topology at the SIP network edge, enabling interaction with authorized users without compromising the infrastructure.
