Experience Portal uses H.323 or SIP connections to switches to transmit and receive Voice over IP (VoIP) data. The system makes use of a variety of Internet protocols to allow the real-time transmission and reception of voice data. In particular, the Media Processing Platform (MPP) servers use protocols such as the User Datagram Protocol (UDP), the Transmission Control Protocol (TCP), and the Media Resource Control Protocol (MRCP) to establish Real-time Transport Protocol (RTP) sessions and to transmit and receive voice data packets.
Note:
To function effectively, the TCP and MRCP ports should not overlap.
In addition, the Experience Portal system can use a Real-time Transport Control Protocol (RTCP) monitor to collect data about the real-time transport of data as delivered by the MPP, the switches, and any other IP components that are configured to send status information about RTP sessions. The RTCP monitor then aggregates all the RTP session data into reports that contain information about packet loss, “jitter,” and other variables concerned with the health of RTP connections in the network. This RTCP monitor provides the system administrator one central location from which to gauge the status and performance of the network with respect to the bandwidth and latency requirements of VoIP.
