12.4(11)T

The resource -update keyword was introduced.

Usage Guidelines

Use the timer cluster-element command to manage the length of time between resource updates and time between announcement messages sent to the gatekeeper. The announcement indication is exchanged at a set interval of time and carries information about the call and endpoint capacity for the zone. This allows the alternate gatekeepers to manage the bandwidth for a single zone even though the gatekeepers are in separate physical devices.

The gatekeeper assumes that the alternate gatekeeper has failed (and assumes that any previously allocated bandwidth is now available) if the gatekeeper does not receive an announcement message within six announcement periods or if the TCP connection with the gatekeeper is detected to be broken.

Lower this interval for closer tracking between elements. Raise it to lower messaging overhead.

Examples

The following command sets the announcement period to 20 seconds:


Router(config-gk)# timer cluster-element announce 20

The following command resets the announcement period to the default value:


Router(config-gk)# no timer cluster-element announce

The following example shows the time between resource update messages to gatekeepers in local cluster being set to 20 seconds:


Router(config-gk)# timer cluster-element resource-update 20

timer irr period

To configure the information request response (IRR) timer, or the periodic interval of IRR messages sent by the gatekeeper, use the timer irr period command in gatekeeper configuration mode. To disable, use the no form of this command.

Modification

12.2(11)T

This command was introduced.

Usage Guidelines

Use this command to configure IRR frequency that is included in the admission confirm (ACF) message. The IRR frequency is set to 240 seconds (4 minutes), based on an average 4-minute call hold time. The IRR allows the gatekeepers to terminate calls for which a disengage request (DRQ) has not been received. If missing DRQs are not a problem, the IRR frequency can be set to a larger value than 4 minutes, minimizing the number of unnecessary IRRs sent by a gateway.

Examples

The following example shows that the IRR timer has been configured with a value of 45, meaning that IRR messages are sent by the gatekeeper every 45 minutes:

12.2(2)XB1

This command was implemented on Cisco AS5850.

Usage Guidelines

The LRQ sequential timing source (SEQ) delay is used to set the time between sending LRQs to remote gatekeepers for address resolution. To resolve an address, the gatekeeper might have several remote zones configured, and it can send the LRQs simultaneously (blast) or sequentially (seq). The gatekeeper chooses the best route based on availability and cost. Using LRQs sequentially results in lower network traffic, but it can increase latency of calls when the most preferred route is unavailable.

Lowering the time increases traffic on the network but might reduce the call setup time.

Examples

The following command sets the LRQ delay timer to 100 milliseconds:


timer lrq seq delay 1

The following command resets the LRQ delay timer to the default value:


no timer lrq seq delay

timer lrq seq delay centisec

To define the time interval between successive sequential location requests (LRQs), use the timer lrq seq delay centices command in gatekeeper configuration mode. To reset to the default, use the no form of this command.

timer media-inactive

To enable the timer for media inactivity detection using the digital signal processor (DSP) (based on RTP as the only criterion) and to configure a multiplication factor based on the real-time control protocol (RTCP) timer interval, use the timer media-inactive command in gateway configuration mode. To reset to the default, use the no form of this command.

timer media-inactive multiple

no timer media-inactive multiple

Syntax Description

multiple

Multiples of the RTCP report transmission interval. Range is 4 to 1000. The default is 5, and the recommended value is 5.

Command Default

A call is considered inactive if no RTP packet activity is detected for a period of time calculated as five times the interval set by the ip rtcp report interval command.

Command Modes


Gateway configuration

Command History

Release

Modification

12.4(4)T

This command was introduced.

Usage Guidelines

When the timer media-inactive command is used, the gateway uses the inactivity timer as a combination of the timer media-inactive command and the ip rtcp report interval command. The timer media-inactive command uses DSP statistics. This capability is based on the configuration of callfeature parameters using application command-line interface (CLI) to enable control.

The media are considered inactive only if there is no transfer of RTP packets in the send direction and no RTP packets in the receive direction. If RTP is present in either the send or receive direction, it is considered active. In this mode, DSP filters out any comfort noise packets, and the presence of any comfort noise packet is considered inactivity in either direction.

The multiple argument (or multiplication factor) is multiplied by the interval that is set using the ip rtcp report interval command. This command configures the average interval between successive RTCP report transmissions for a given voice session. For example, if the value argument is set to 25,000 milliseconds, an RTCP report is sent every 25 seconds, on average. If no RTP packets are received during the calculated interval, the call is disconnected. The gateway signals the disconnect to the VoIP network and the time-division multiplexing (TDM) network so that upstream and downstream devices can clear their resources.

Examples

The following example uses the ip rtcp report interval command to set the reporting interval to 5000 milliseconds, and then the timer media-inactive command to set the multiplication factor to 10. The result is that calls detected as inactive for 50 seconds (5,000 milliseconds times 10) will be disconnected.


Router(config)# ip rtcp report interval 5000
Router(config)# gateway
Router(config-gateway)# timer media-inactive 10
Router(config-gateway)# exit

timer receive-rtcp

To enable the Real-Time Control Protocol (RTCP) timer and to configure a multiplication factor for the RTCP timer interval for Session Initiation Protocol (SIP) or H.323, use the timer receive-rtcp command in gateway configuration mode. To reset to the default, use the no form of this command.

timer receive-rtcp timer

no timer receive-rtcp timer

Syntax Description

timer

Multiples of the RTCP report transmission interval. Range is 0 to 1000. Default is 0. Recommended value is 5.

Command Default

The default value for the timer argument is 0 multiples, which disables the timer so that no silence detection is in effect.

This command was integrated into Cisco IOS Release 12.2(8)T. Support for the Cisco AS5300, Cisco AS5350, Cisco AS5400, and Cisco AS5850 is not included in this release.

12.2(11)T

This command was implemented on the Cisco AS5300, Cisco AS5350, and Cisco AS5400.

Usage Guidelines

The timer receive-rtcp command uses library-based detection and the receipt of either Real-Time Protocol (RTP) or RTCP packets is considered activity on a call. Silence detection occurs only if there are no packets received for both RTP and RTCP.

When the ip rtcp report interval and timer receive-rtcp commands are used, the gateway uses RTCP report detection, rather than RTP packet detection, to determine whether calls on the gateway are still active or should be disconnected. RTCP report detection is therefore more reliable than RTP packet detection because there can be periods during voice calls when one or both parties are not sending RTP packets.

One common example of a voice session in which no RTP is sent is when a caller dials into a conference call and mutes that endpoint. If voice activity detection (VAD, also known as silence suppression) is enabled, no RTP packets are sent while the endpoint is muted. However, the muted endpoint continues to send RTCP reports at the interval specified by the ip rtcp report interval command.

The timer receive-rtcp timer argument (or m factor for multiplication factor) is multiplied by the interval that is set using the ip rtcp report interval command. If no RTP or RTCP packets are received during the calculated interval, the call is disconnected. The gateway signals the disconnect to the VoIP network and the time-division multiplex (TDM) network so that upstream and downstream devices can clear their resources. The gateway sends a Q.931 DISCONNECT message to the TDM network and a SIP BYE or H.323 ReleaseComplete message to the VoIP network to clear the call when the timer expires. The Q.931 DISCONNECT message is sent with a cause code value of 3 (no route) for SIP calls and a cause code value of 41 (temporary failure) for H.323 calls. No Q.931 Progress Indicator (PI) value is included in the DISCONNECT message.

To show timer-related output for SIP calls, use the debug ccsip events command. To show timer-related output for H.323 calls, use the debug cch323 h225 command.

Examples

The following example sets the multiplication factor to 10 (or x * 10, where x is the interval that is set with the ip rtcp report interval command):


Router(config)# gateway
Router(config-gateway)# timer receive-rtcp 10
Router(config-gateway)# exit
