For detailed information on how to configure these applications and features, refer to the Cisco IOS Voice Configuration Guide.

q850-cause

To map a Q.850 call-disconnect cause code to a different Q.850 call-disconnect cause code, use the q850-cause command in application-map configuration mode. To disable the code-to-code mapping, use the no form of this command.

q850-cause code-id q850-cause code-id

no q850-cause code-id q850-cause code-id

Syntax Description

Command Default

No mapping occurs.

Command Modes

Application-map

Command History

Release	Modification
12.4(9)T	This command was introduced.

Usage Guidelines

Use this command to map a Q.850 call-disconnect cause code to any different Q.850 call-disconnect cause code.

Use this command in conjunction with the application and map commands.

This command operates only on incoming H.323 call legs that are disconnected by a call-control application.

Examples

The following example maps cause code 34 to cause code 17:

Router(config)# application

Router(config-app)# map

Router(config-app-map)# q850-cause 34 q850-cause 17

Router(conf-voi-serv)# qsig decode

Related Commands

Command	Description
supplementary-service h450.7	Globally enables H.450.7 supplementary services capabilities exchange.

query-interval

To configure the interval at which the local border element (BE) queries the neighboring BE, use the query-interval command in Annex G Neighbor BE Configuration mode. To remove the interval, use the no form of this command.

query-interval query-interval

no query-interval

Syntax Description

query-interval

Frequency, in minutes, at which this BE should query the specified neighbor BE for descriptors. Default is 30. A value of 0 disables periodic querying. Note If caching is disabled, this value is ignored.

Command Default

30 minutes

Command Modes

Annex G Neighbor BE Configuration

Command History

Release	Modification
12.2(2)XA	This command was introduced.
12.2(4)T	This command was integrated into Cisco IOS Release 12.2(4)T.
12.2(2)XB1	This command was implemented on the Cisco AS5850.
12.2(11)T	This command was integrated into Cisco IOS Release 12.2(11)T.

Usage Guidelines

Use this command to configure the interval at which the local BE queries the neighboring BE. Use this command only if you want a query interval other than 30 minutes.

Examples

The following example sets the query interval to 45 minutes:

Router(config-annexg-neigh)# query-interval 45

Related Commands

Command	Description
emulate	Configures the local BE to cache the descriptors received from its neighbors. If caching is enabled, the neighbors are queried at the specified interval for their descriptors.
local	Configures the identifier for the neighbor BE.
session transport	Configures the neighbor's port number that is used for exchanging Annex G messages.
