Advanced Media Termination Operations in the Network
The Oracle® Enterprise Session Border Controller (ESBC) can interconnect a Advanced Media Termination domain with a PSTN domain or another Advanced Media Termination domain.
The following illustration shows how the ESBC supports Advanced Media Termination operations.
In the preceding illustration:
- The Advanced Media Termination Agent and the Advanced Media Termination Applications can communicate on a proprietary interface on a web socket.
- The Advanced Media Termination Agent can be behind a NAT interface with the ESBC on a Advanced Media Termination configuration specific realm using SIP.
- The ESBC can connect with a PSTN or Media Gateway on a different realm, for example "core," having RTP or SRTP media.
- In a call flow initiated by a Advanced Media Termination Client, the Advanced Media Termination Agent receives call setup from the Advanced Media Termination Client on a proprietary interface and the Advanced Media Termination Agent initiates a SIP session towards the ESBC.
- The ESBC can interwork with Advanced Media Termination and specific ICE-STUN and RTCP-Mux features towards the Advanced Media Termination Agent and a normal SIP, RTP-SRTP interface towards a PSTN-Media Gateway.
- SDES-SRTP media can flow directly from the Advanced Media Termination application to the ESBC.
