RTCP Relay for pass-through calls with RTCP enabled on both legs | RTCP is relayed between two end users. The SBC will not terminate the RTCP sessions; however, it will set up the media-path to forward RTCP packets from one party to the other. This is the default and recommended approach for handling RTCP for pass-through calls. | RTCP termination for a pass-through call with RTCP enabled on only one leg | | RTCP for transcoded calls legs | If RTCP is enabled on the leg, the SBC will terminate RTCP. |
|
In either pass-through or termination modes, the SBC collects packet RTCP statistics and reports them for output to CDRs. Configurable parameters include:
- Media peer inactivity—Configure media peer inactivity time out value. When using this feature, you must also set the flag,
peerAbsenceAction, from the Packet Service Profile. - Media port range—Use this control to set the UDP media port range for RTP and RTCP.
- Media RTCP control—Configure sender report interval.
