Local Gateway (LBO)
-------------------
This call type occurs in the following situations for an endpoint in a site that
has Local Gateway (Local Breakout):
* When the endpoint places a call to reach a destination in the PSTN through the
Local Gateway
* When the endpoint receives a call from the PSTN through the Local Gateway
The Local Gateway is used to connect to the PSTN locally. In this case, it must
be possible on a per-call basis to select the Local Gateway breakout and there
must be selectable per-site routing through the Local Gateway (that is,
International, National, Service, and so on).
The call type includes:
* SIP/SCCP signaling traffic for the endpoint between the endpoint and Cisco
Unified Communications Manager
* SIP signaling traffic for the Local Gateway between the Local Gateway and Cisco
Unified Communications Manager
* Media traffic between the endpoint and Local Gateway
Off-Net Call (Local Gateway)

+---------------+--------------------------------------------------------------------+
| Usage | * Called number follows the Numbering Plan requirements |
| | * Called number can include an access code if necessary |
| | * Any target number can be used, unless it is restricted by |
| | Class of Service |
| | * Off-net dialing can be completed in two ways: |
| | |
| | * When PDD is unavoidable, user can wait for interdigit |
| | timeout or press # without waiting for interdigit |
| | timeout |
| | * E.164 numbering format is supported with + as the first |
| | digit |
| | * The calling number is one of: |
| | |
| | * DDI of the DN |
| | * Site Published PSTN number if the DN does not have a |
| | DDI, or |
| | * Site Published PSTN number regardless of the |
| | availability of DN DDI |
+---------------+--------------------------------------------------------------------+
| Accessibility | User can perform Off-Net call from any endpoint registered with |
| | Cisco Unified Communications Manager |
+---------------+--------------------------------------------------------------------+
| Usage Example | User can dial any PSTN number from their phone |
+---------------+--------------------------------------------------------------------+
| Default | * Available to all users |
| Configuration | * DDI of the DN is sent if available; otherwise, Site Published |
| | PSTN number is sent |
| | * Codec depend on trunk bandwidth |
+---------------+--------------------------------------------------------------------+
| Configuration | * Feature availability cannot be changed |
| Choices | * Can be configured to send only the Site Published PSTN |
| | number as the Calling Number PRI, BRI, and so on |
+---------------+--------------------------------------------------------------------+
| Redundancy | Available to users without restrictions |
+---------------+--------------------------------------------------------------------+
| Survivability | Available to users in fallback mode, with the following |
| | restrictions: |
| | |
| | * Phone must be registered to the SRST gateway |
| | * No COS is available during survivability mode |
+---------------+--------------------------------------------------------------------+
+---------------+--------------------------------------------------------------------+
| Endpoint | * Cisco IP phones |
| Types | * Cisco ATA |
| Supported | * Cisco VG |

| Examples | Case 1: Using Trunk Transformation CSS to convert DN to DDI |
| | Phone A (DN=8 300 1234; External Mask=+14085289001) |
| | Dial 9 12134225001 |
| | Local GW Trunk {uses Called, Calling, Redirecting and Connected |
| | Transformation CSS} |
| | Outbound from CCM - CDPN = +12134225001; CGPN=+14085289001 |
| | Inbound Connected Number +12134225001 |
