Feature Overview
The Cisco IOS software features supported on the Cisco AS5850 universal gateway in Cisco IOS Release 12.2(11)T are listed in the following section. These features were previously released on other Cisco platforms. Therefore, it is important to note that the Cisco AS5850 platform name may not be specifically noted in the individual feature documents.
Supported IOS Features
The Cisco IOS software features being implemented on the Cisco AS 5850 in this release are:
FGD-OS 911 Calls
The 911 feature can be run as residential gateway (RGW) or trunking gateway (TGW) feature:
The user can make a 911 call to an Emergency Service Bureau (ESB), and the call is maintained as long as the ESB does not hang up. If the user hangs up, the call is maintained. If the user hangs up and picks up the phone again, the call resumes. If the user hangs up and does not pick up the phone again, the ESB can ring the user and resume the call.

Determining Platform Support Through Cisco Feature Navigator
Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.
Use Cisco Feature Navigator to find information about platform support and Cisco IOS and Catalyst OS software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required.

Configuring FGD-OS 911 functionality
No special configuration tasks are required to initiate Media Gateway Control Protocol Basic CLASS and Operator Services (MGCP BCOS). MGCP BCOS co-resides with MGCP channel-associated signaling (CAS) Private Branch Exchange (PBX) and AAL2 PVC software, for which configuration activities are required. These are discussed in MGCP CAS PBX and AAL2 PVC at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t2/ftmgcptk.htm
Configuring Hierarchical Endpoint Naming
To configure custom T3 hierarchical endpoint naming, perform the following steps beginning in privileged EXEC mode.
Verifying Endpoint Naming
To verify MGCP-controlled endpoints configured for SS7 and ISDN PRI, use the show mgcp endpoint command in privileged EXEC mode.
Note
The following example shows MGCP endpoints for NAS package:

Hierarchical Endpoint Naming Example
The following example shows the T3 endpoint naming convention allowing customizing on a per-MGCP profile basis:
Router# configure terminalRouter(config)# mgcp profile defaultRouter(config-mgcp-profile)# endpoint naming t3Router(config-mgcp-profile)# endRouter#
Command Reference
This section documents new commands on the Cisco AS5850 universal access server. All other commands used with this feature are documented in the Cisco IOS Release 12.2 command reference publications.
endpoint naming
To customize the T3 endpoint naming convention on a per MGCP profile basis, use the endpoint naming command in MGCP profile configuration mode. To disable endpoint naming, use the no form of this command.
endpoint naming {t1 | t3}
no endpoint naming
Syntax Description
Defaults

Command Modes
MGCP profile configuration
Command History
Usage Guidelines
The option to select between a flat endpoint naming convention and a hierarchical T3 endpoint naming convention gives call agents flexibility without enforcing one naming convention. Signaling, backhauling, and trunks using SS7 are supported. t3 naming conventions on XCC signaling types, SS7, and ISDN are not supported.
Examples
The following example shows the T3 endpoint naming convention on an MGCP profile:
Router# configure terminalRouter(config)# mgcp profile defaultRouter(config-mgcp-profile)# endpoint naming t3Router(config-mgcp-profile)# endRouter#
