Flow-status AVP
The Flow-status AVP (511) is based on SDP direction. Tests for SDP are performed in the following order:
SDP State | Flow-Status AVP (511) Set to |
---|---|
port in the SDP m-line is 0 | REMOVED (4) |
Transport in m-line is "TCP" or " TCP/MSRP" | ENABLED (2) |
a=recvonly and <SDP direction> = UE originated | ENABLED-DOWNLINK (1) |
a=recvonly and <SDP direction> = UE terminated | ENABLED-UPLINK (0) |
a=sendonly and <SDP direction> = UE originated | ENABLED-UPLINK (0) |
a=sendonly and <SDP direction> = UE terminated | ENABLED-DOWNLINK (1) |
a=inactive | DISABLED (3) |
a=sendrecv or no direction attribute | ENABLED (2) |
UE originated - Call originator creates the SDP being considered.
UE terminated - Call terminator creates the SDP being considered.
Flow-status AVP is always created according and requires no configuration.
