This profile specifies the configuration for OPTIONS PING. On the SBC main screen, go to Configuration > System Provisioning > Category: Trunk Provisioning > IP Peer > Path Check. The Path Check window is displayed. You can check the Path Check for each Address Context, Zone and IP Peer created, or for all Address Contexts, Zones and IP Peers. Use the drop-down box to select the desired Address Context, Zone and IP Peer. IP Peer - Path Check Edit Window Parameter Descriptions: Parameter Description Profile Specifies the path check profile name used for OPTIONS ping. 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. If the IP Address is configured and Path Check needs to be enabled for that IP Address, ensure Host Name is not configured. 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. If the 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 Path Check task performs SRV lookup to resolve the port numbers. The resolved port numbers are used to send OPTIONS ping to the IP Peer. When the Host Port is set to value other than the value 0, the Path Check task does not perform SRV lookup. It uses the configured port to send OPTIONS ping to the IP Peer. To use SRV, enable the IPSP flag No Port Number5060. State Specifies if the active pinging is enabled or not. The options are: Status Update Enable this flag to provide OPTIONS-based status update support. The options are: 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. Make the required changes and click Save. Ribbon recommends to not configure Path Check Profile and SIP ARS Profile on the same peer to avoid unexpected results. As a general rule, the Path Check Profile is configured on the access leg where there is less traffic, and the ARS Profile is configured on the peer leg where there is continuous traffic. This option provides local admin state and remote admin state for a peer. IP Peer - Path Check Commands Parameter Descriptions: Parameter Description Local Admin State Specifies the local admin state of the peer. Specifies the remote admin state of the peer. Select the required command and click Select. From the pop-window, choose your preference for the selected Path Check Command. IP Peer - Path Check Command pop up window Select the desired option and click the "Command Name" button to implement the option. Click OK to exit.
