Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases. Refer to the SBC SIP Transparency Implementation Guide for additional information. Use the Zone window to create and work with zones. A zone is used to group a set of objects in a particular customer environment. A zone can also be referenced by a SIP or H.323 trunk group. Trunk group names must be unique across all address contexts, zones, and trunk group types. Also, IP peer names must be unique across all address contexts, and zones. On the SBC main screen, navigate to one of the following paths: By default all zones are listed in the Zone window. Select an Address Context to list only the zones in that address context. To create a new zone: Click New Zone. Use the following table to configure the zone and then click Save. Zone Parameters: Name Specifies the name of the zone. Must be 1 to 23 characters. The name must be unique across all address contexts. ID specifies a unique numeric ID for this zone. The value ranges from 1 to 4096. The ID must be unique across all address contexts. If Disabled (default), the Global Loop Detection flag takes precedence. If Enabled, Loop Detection is disabled irrespective of the Global Loop Detection flag. DNS Group Select the name of the default DNS server group for the zone. Select the type of device facing this Zone. The options are: Enable this option flag to relay REGISTER messages using the routes from a PSX. Options are: Specifies if dialog transparency is enabled for SIP messages processed in the zone. If enabled, SBC sends "Call-ID", "From" tag, and "To" tag transparently in the outgoing message. The parameter Dialog Transparency must be enabled in both the ingress and egress zones. Otherwise, the To enable Dialog Transparency for a zone, first disable all SIP Sig Ports for that zone. The following features are not supported on the SBC when Dialog Transparency is enabled: Use this option to natively generate the Call ID even when dialog transparency is enabled. The Call ID is generated on the egress side. You must enable 'Dialog Transparency' to use this flag. Beginning in release 8.0, Load Balancing Service configuration applies only to media SBC (M-SBC) clusters in distributed SBC SWe deployments. The M-SBC load balancing distributes media requests among nodes. Load balancing of REGISTER or INVITE requests through retargeting is no longer supported and should not be configured. Use this option to control whether the Mode, Action and Block Direction configuration is active in IP peers within the zone. Refer to System Provisioning - IP Peer for information on these options. Options are: Use this Zone/Trunk Group parameter to associate a SIP Adapter Profile configured for flexible policy (Profile Type=Flexible Policy) with a particular Zone/Trunk Group. If a Flexible Policy Adapter Profile is provisioned both at the trunk group and zone levels, the trunk group’s profile takes precedence. If an Input Adapter Profile is configured, it is applied first to manipulate the PDU and then the Flexible Policy Adapter Profile rules are applied on the manipulated PDU. Set this parameter to Remote Party ID to allow the SBC to pick the SIP header for calls from surrogate registered endpoints when the username in the From header is received as anonymous. To edit a zone: To delete a zone: The zone commands are available from both system-level and configure modes. These command allows you to perform system-level commands against a particular zone, such as recovering blacklisted endpoints and resetting statistics counts on all signaling ports. When a zone is selected from the Zone list window, the Zone Commands window appears at the bottom of the Zone window. Select a command from the Commands drop-down list: The commands are described in the following table: Removes any CAC entry for the specified source IP address. Recovers all blacklisted endpoints in this zone. NOTE: This command only applies for peers blacklisted using the ARS mechanism (not via PATHCHECK). Recovers a blacklisted endpoints in this zone identified by IP address and port. NOTE: This command only applies for peers blacklisted using the ARS mechanism (not via PATHCHECK).To View the Zone List

The SBC uses the Contact header elements specified in the profile as additional keys when it creates or retrieves registration control blocks (RCBs) for users registering through this zone. SIP Header For Anonymous Call Crank Back Profile Select a crankback profile to apply to the zone. For flexibility, crankback profiles can be assigned at three levels: trunk group, zone, and global. By default, the "default" crankback profile is assigned at the SBC global level, while the trunk group and zone level crankback profile settings are initially empty (" "). Thus in the SBC default configuration, trunk groups and zones inherit the default crankback profile from the global level. However, you have the option to configure a profile at the trunk group or zone level. The user-specified profile assigned at the most specific level takes precedence. To Edit a Zone
