Parameter

Description

Profile

Specifies the path check profile name used for OPTIONS ping.

Host Name

Specifies the FQDN value of the peer. It will be resolved using DNS and the resulting servers will be pinged using SIP OPTIONS requests. The value ranges up to 63 characters.

Info
titleNote

If  IP Address is configured and Path Check needs to be enabled for that IP Address, ensure Host Name is not configured.

Host Port

Specifies the TCP/UDP port number of the peer. The peer's servers will be pinged using SIP OPTIONS requests at this port. The value ranges from 0 to 65535 and the default value is 5060.

Info
titleNote

If IP Port is configured and Path Check needs to be enabled for that IP Port, ensure Host Port is not configured.

When set to 0, the pathCheck task performs SRV lookup to resolve the port numbers. The resolved port numbers are used to send OPTIONS ping to the IP Peer.

When hostPort is set to value other than the value 0, the pathCheck task does not perform SRV lookup. It uses the configured port to send OPTIONS ping to the IP Peer.

Info
titleNote

If Host Port is set to 0, the SBC supports SRV.

State

Specifies if the active pinging is enabled or not. The options are:

  • disabled (default)
  •  enabled

Status Update
Support

Enable this flag to provide OPTIONS-based status update support. The options are:

  • disabled (default) - The SBC does not include Allow and Accept headers while generating OPTIONS ping request towards the peer.
  •  enabled - The SBC does not include includes Allow and Accept headers while generating OPTIONS ping request towards the peer.
Info
titleNote

Status Updates only apply when new calls are sent to a peer. They do not impact messages belonging to existing calls or new calls received from the peer.

Status Update is Seen By:When:
PeerPeer restarts
PeerPeer is manually blocked
PeerPeer's congestion state changes (this update is ignored by SBC)
SBCPeer has restarted indicating it is ready to receive calls
