Possible completions:
dscpValue - DSCP value (0-63) for intercepted signaling packets sent on this port.
ipAddress - IPV4/IPV6 Address of the mediation server for signaling interception.
mode - The operational mode of the signaling connection towards the mediation server.
portNumber - UDP/TCP port number of the mediation server for signaling interception.
protocolType - The protocol used by the mediation server for signaling interception (TCP/UDP).
state - The administrative state of the signaling connection towards the mediation server. |
