If there is more than one SRS associated with the SRS Cluster, the SBC records on both the legs (Ingress and Egress). The first two recordings are on Ingress leg and the rest on Egress.
For Quad SIPREC, there are four recordings triggered. Two recordings are triggered on the Ingress leg and two on the Egress leg.
If there is more than one SRS Group configured, it is recommended to set recordingType to "both legs" or "all legs".
When SIPREC is selected as the Recorder Type, and Recording Type is selected as “both legs” and “all legs”, the SBC by default records the ingress leg.
