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

| 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        |
