The Telephony component

Last Updated : Jun 05, 2026 |

The MPP Telephony component provides all telephony services required by the Experience Portal system, including call control and media processing.

The telephony subsystem can be connected to:

  • Direct connection to Communication Manager, a VoIP-based PBX gateway, using either the International Standard for Multimedia Communication Over Packet-switched Networks (H.323) or Session Initiation Protocol (SIP) for signaling and Real-time Transport Protocol (RTP) to transport the actual audio data stream in a connection.

  • Proxied SIP connection through Avaya Aura Session Manager to Communication Manager, Communication Server 1000, the Avaya G860 Media Gateway or Third-party SIP gateways.
