IMPORTANT

The Transparency Profile is the recommended method of configuring transparency on the SBC Core for new deployments as well as when 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.

A zone is used to group a set of objects unique in a particular customer environment. A zone can also be referenced by a SIP or H.323 trunk Group.

Note

Trunk group names must be unique across all address contexts, zones, and trunk group types. 

Note

IP peer names must be unique across all address contexts, and zones.

To View Zone

On the SBC main screen, go to Configuration > System Provisioning > Category: Base Provisioning > Zone.

The Zone window is displayed.

System Provisioning - Zone

 

The Zone can be checked for each Address Context or for all the Address Contexts created. Use the drop-down box to select the desired Address Context.

Zone Parameters

 


Parameter


Description

Name

Specifies the name of the zone. Must be 1-23 characters. The value ranges up to 23 characters.

Note

Zone name is unique across all address contexts.

ID

Unique ID of this zone. The value ranges from 1 to 4096.

Note

Zone ID is unique across all address contexts.

Disable Zone Level Loop Detection

  • If disabled (default), Global Loop Detection flag takes precedence.

  • If enabled, Loop Detection is disabled, irrespective of Global Loop Detection flag.

DNS Group

The name of the DNS group. Select the DNS group from the drop-down list.

Remote Device Type

Specifies the type of device facing this Zone. The options are:

  • None (default)
  • Access Device
  • App Server
  • Core
  • Nni
Domain NameSpecifies the name of the fully qualified domain name for this Zone. The value ranges up to 63 characters.
SIP Register Relay

Enable flag to relay REGISTER using the routes from PSX. Options are:

  • Disabled (default)
  • Enabled
Dialog Transparency

This parameter specifies if dialog transparency is enabled for SIP messages processed in that zone. If enabled, SBC sends "Call-ID", "From" tag, and "To" tag transparently in the outgoing message.

Note

The parameter Dialog Transparency must be enabled in both the ingress and egress zones. Otherwise, the sonusSbxDialogTransparencyMisConfiguredNotification alarm is raised on the zone in which the flag is disabled.

 

Note

To enable Dialog Transparency for a zone, first disable all Sip Sig Port for that zone.

 

  • Disabled (default): SBC translates the dialog identifiers in the Target-Dialog header received in INVITE and REFER messages and sends the Target-Dialog header with translated dialog identifiers on the other leg.
  • Enabled: Target-Dialog header translation is not performed. However, the header is transparently passed if configured in transparency profile.

 

Note

 

The following features are not supported on SBC when Dialog Transparency is enabled:

  • Support of local handling of REFER (REFER relay is supported)
  • Late media support 
  • Dialog Transparency support in REGISTER
  • NICE recording call flows
  • GW-GW support

For feature functionality and configuration guidance, see Downstream Forking Support and Configuring Downstream Forking with Dialog Transparency.


Flexible Policy Adapter Profile

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 Flexible Policy Adapter Profile is provisioned both at the trunk group and zone levels, the trunk group’s profile takes precedence. If Input Adapter Profile is configured, it is applied first to manipulate the PDU and then Flexible Policy Adapter Profile rules are applied on the manipulated PDU.

Note

 Flexible Policy is not supported on ERE and is intended for use with an external PSX only.

SIP Header For Anonymous Call

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.

  • None – The SBC uses default behavior.
  • Remote Party ID – The SBC picks the SIP Header when a username in the FROM header is received as anonymous.
