Back to Configuring SBC for WRTC
To configure inter/intra Direct Media call:
- Ingress and egress Trunk Groups must have the flag
directMediaAllowed enabled. - Ingress and egress Trunk Groups must have same
directMediaGroupId. - PSP for Trunk Groups must have the flag
useDirectMedia enabled. - IP signaling profile for AS TG must have the flag
sendDirectMediaInfoInSdpAttribute enabled (for xdmi).
To configure
...
antitrombone Direct Media call,
- AS Trunk group must have the flag
directMediaAntiTrombone enabled.
The basic Direct Media call with ICE and DTLS configuration contains:
