Integrating Data and Voice Services for ISDN PRI Interfaces on Multiservice Access Routers

Revised: June 19, 2006, OL-10383-01

First Published: February 27, 2006

This document describes how to configure ISDN PRI interfaces to support the integration of data and voice calls on multiservice access routers. This feature enables data (dial-in, dial-on-demand routing [DDR], and DDR backup) and voice call traffic to occur simultaneously from the supported ISDN PRI interfaces. You can also enable multilevel precedence and preemption (MLPP) for DDR calls over the active voice call when no idle channel is available during the DDR call setup.

Information About Integrating Data and Voice Services for ISDN PRI Interfaces

Before you configure integrated data and voice services on ISDN interfaces, you should understand the following concepts:

•Integrated Services for Multiple Call Types

•Resource Allocation for Voice and Data Calls

•MLPP Call Preemption over Voice Calls

Integrated Services for Multiple Call Types

ISDN interfaces can support both data calls and voice calls. Typically, this is done using one interface for data and another for voice. This feature enables data (dial-in, dial-on-demand routing [DDR], and DDR backup) and voice call traffic to occur simultaneously from the supported ISDN PRI interfaces. To enable integrated services, the interface used for incoming voice calls is configured to accept multiple voice call types.

Figure 1 shows an ISDN network configured for integrated data and voice services.

Figure 1 Integrated Voice with DDR Interface for WAN Failure Backup

Resource Allocation for Voice and Data Calls

Voice calls use DSP resources and data calls use HDLC resources for transmission. When an interface is configured for integrated services, the gateway allocates the HDLC resources dynamically during call setup and frees them back to the HDLC resource pools when the call terminates. This allows spare HDLC resources to support ISDN PRI data calls and DSP resources to support voice calls.

MLPP Call Preemption over Voice Calls

Multilevel precedence and preemption (MLPP) is the placement of priority calls through the network. Precedence designates the priority level that is associated with a call. Preemption designates the process of terminating lower-priority calls so that a call of higher precedence can be extended.

Preemption levels are assigned to outgoing voice calls and DDR backup calls. DDR backup is used to provide backup to a WAN link.

From the gateway, voice and DDR backup calls are controlled by different entities:

•The preemption level of an outgoing voice call is determined using the selected outbound POTS dial peer.

•The preemption level of a DDR backup call is determined using the dialer map class.

A trunk group is used as the common channel resource pool for outgoing voice call and DDR backup calls. Calls with a higher precedence preempt an active outgoing voice call, of a lower precedence, if an idle B channel is not available. An ISDN interface that is configured for integrated mode is assigned to this trunk group to allow dialer resources and voice resources to request an idle B channel from the same resource pool.

Preemption of Outgoing Voice Calls

The trunk group and preemption level are configured as part of a map class, which can be attached to a dialer map. The dialer map class supplies configuration parameters to dialer interfaces and can be referenced from multiple dialer interfaces.

During dial-on-demand routing (DDR) backup call setup, an idle B channel is selected from the trunk group. When no idle channel is found, the trunk group resource manager (TGRM) selects a B channel on the basis of the following:

•The B channel currently active with a connected outgoing voice call

•The preemption level of the connected voice call being lower than the preemption level of a DDR call

A guard timer, configured for the trunk group, is used to delay the idle channel notification and defer the DDR setup to allow the remote channel time to become ready and accept the incoming call with the higher precedence.

By default, the preemption level of dialer calls is set to the lowest level (routine) to disable the MLPP service for a DDR call.

The preemption level of an outgoing voice call is defined from the selected outbound POTS dial peer. During the voice call setup, the trunk group resource manager (TGRM) selects an idle B channel from a trunk group on the basis of the following:

•The call ID of an outgoing voice call

•The preemption level of an outgoing call as defined by the POTS dial peer

•The voice interface B channel information of an outgoing voice call

When the preemption call notification is received, the TGRM saves the outgoing voice call to the preemption level link list based on FIFO.

Preemption Tones

When an outgoing voice call is preempted by a DDR backup call, the preemption call treatment starts by providing a preemption tone and starting the tone timer.

An MLPP preemption tone is a special tone played to the voice call announcing that the line is about to be seized by a call with a higher precedence. A steady tone, 1060 ms in duration, is played on all legs of the call until the user hangs up or the preemption tone times out.

•For the telephony leg of the call, the preemption tone is played using the DSP.

•For the IP leg (across the VoIP network) of the call, the preemption tone is played as media.

•For the ephone leg on Cisco CME, a reorder tone is played for the local user and a preemption tone is played for the remote user.

Preemption Cause Codes

When the preemption tone timer is expired and the call is still in a connected state, both call legs are disconnected by the gateway with the following cause code:
Preemption - Circuit Reserved 0x8
If you release the call before the preemption tone timer expires, the following cause code is used:
Normal Call Clear 0x10
In both cases, the following internal cause code is used for the release calls:
Preemption Circuit Reserved 0x8
How to Configure Integrated Data and Voice Services for ISDN PRI Interfaces

This section describes the tasks required to configure integrated services for ISDN interfaces:

•Configuring the ISDN PRI Interface for Multiple Call Types (Required)

•Configuring MLPP Call Preemption over Outgoing Voice Calls (Optional)

Configuring the ISDN PRI Interface for Multiple Call Types

An ISDN serial interface configured for integrated mode supports data and voice calls using incoming call type checking to accept incoming voice and data calls when an inbound voice dial peer is matched.

Perform the following tasks to configure integrated services:

•Prerequisites

•Configuring the POTS Dial-Peer Incoming Called Number

•Configuring the Data Dial Peer Lookup Preference

•Enabling Integrated Services

•Creating a Trunkgroup and Configuring Maximum Calls Based on Call Type

•Disabling Integrated Services

Prerequisites

Unlike voice calls, which use DSP resources, data calls use HDLC resources for transmission. To use the integrated services feature, the gateway must allocate HDLC resources dynamically during call setup and free them back to the HDLC resource pools when the call terminates.

Use the following show commands to view the availability of HDLC resources:

•show tdm connections

The following example shows HDLC resources on the TDM side.
Router# show tdm connections slot 0
              Active TDM connections for slot 0

Configuring the POTS Dial-Peer Incoming Called Number

The call type of an incoming call is determined using the incoming dial-peer. For data dial peer matching, the called number of an incoming call is used to match the incoming called-number of POTS dial peers. Use the following procedure to configure the POTS dial peer and incoming called number.

SUMMARY STEPS

1. enable

2. configure terminal

3. dial-peer data tag pots

4. incoming called number string

DETAILED STEPS

Command or Action

Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

dial-peer data tag pots

Example:

Router(config)# dial-peer data 100 pots

Creates a data dial peer and enters data dial-peer configuration mode.

Step 4

incoming called number string

Example:

Router(config-dial-peer)# incoming called number 4085550110

For data dial-peer matching, only the called number of an incoming call is used to match the incoming called number of POTS dial peers. Wild cards are accepted.

Note The string must match the dialer string on the remote gateway.

Configuring the Data Dial Peer Lookup Preference

To optimize data or voice dial-peer searches for incoming ISDN calls, configure the preference of dial-peer lookup during the call type checking. Use the following procedure to configure a search for dial peers by type.

SUMMARY STEPS

1. enable

2. configure terminal

3. dial-peer search type {data | none | voice} {data | voice}

DETAILED STEPS

Command or Action

Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

dial-peer search type {data | none | voice} {data | voice}

Example:

Router(config)# dial-peer search type data voice

Configures the preference of voice or data dial-peer lookup during the calltype checking for incoming ISDN calls.

•data—Search dial peers with type data first.

•none—Search dial peers with any type at the same preference.

•voice—Search dial peers with type voice first.

By default, the data dial peer is searched first before voice dial peers.

Enabling Integrated Services

Enabling integrated services allows data and voice call traffic to occur from ISDN PRI interfaces simultaneously.

When an interface is in integrated service mode:

•ISDN performs calltype checking for the incoming call. The call is rejected by ISDN if no voice or data dial peer is matched for an incoming call.

•The voice option for the isdn incoming-voice command, which treats incoming calls as voice calls, is not available.

By default, the integrated service option is disabled from the supported interfaces. Use the following procedure to enable integrated mode on a serial interface.

SUMMARY STEPS

1. enable

2. configure terminal

3. interface serial slot/port:timeslot

4. shutdown

5. isdn integrate calltype all

6. no shutdown

DETAILED STEPS

Command or Action

Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

interface serial slot/port:timeslot

Example:

Router(config)# interface serial 0/1:15

Specifies a serial interface for ISDN PRI channel-associated signaling and enters interface configuration mode.

Step 4

shutdown

Example:

Router(config-if)# shutdown

Shuts down the interface.

Step 5

isdn integrate calltype all

Example:

Router(config-if)# isdn integrate calltype all

Enables the serial interface for integrated mode, which allows data and voice call traffic to occur simultaneously.

Note This configuration disables the voice option for the isdn incoming-voice command on the interface.

Step 6

no shutdown

Example:

Router(config-if)# no shutdown

Returns the interface to the active state.

Creating a Trunkgroup and Configuring Maximum Calls Based on Call Type

After an ISDN interface is assigned to a trunk group, you can configure maximum incoming and outgoing calls based on the call type (voice or data) or direction (inbound or outbound) through the trunk group.

Note If trunk groups are not configured, data and voice calls are treated as first-come first-served.

Use the following procedure to create a trunk group and configure maximum calls based on call type.

SUMMARY STEPS

1. enable

2. configure terminal

3. trunk group name

4. max-calls {any | data | voice} number [direction [in | out]]

DETAILED STEPS

Configuring MLPP Call Preemption over Outgoing Voice Calls

This feature adds support for multilevel precedence and preemption (MLPP) for dial-on-demand routing (DDR) backup calls over outgoing voice calls.

Precedence designates the priority level that is associated with a call. Preemption designates the process of terminating lower-precedence calls so that a call of higher precedence can be extended. DDR backup is used to provide backup to a WAN link using any DDR or a dial-capable interface, like ISDN PRI interfaces.

From the gateway, voice and DDR backup calls are controlled by different entities.

•The preemption level of an outgoing voice call is determined using the selected outbound POTS dial peer.

•The preemption level of a DDR backup call is determined using the dialer map class.

A DDR backup call with higher precedence preempts the active outgoing voice call with a lower precedence if the idle B channel is not available from a trunk group during the DDR backup call setup. If MLPP is not configured, data calls wait for a free channel.

Perform the following tasks to configure call preemption:

•Enabling Preemption on the Trunk Group

•Defining a Dialer Map Class and Setting the Preemption Level

•Associating the Class Parameter on the Dialer Interface

•Disabling TDM Hairpinning on the Voice Card

•Configuring the POTS Dial Peer for Outgoing Voice Calls

•Troubleshooting Tips for Integrated Data and Voice Services

Enabling Preemption on the Trunk Group

A trunk group is used as a common channel resource pool for idle channel allocation for outgoing voice calls and DDR backup calls. Multiple ISDN PRI interfaces that have been configured for integrated services are assigned to this trunk group to build up a channel resource pool for both voice and data calls. Enabling preemption on the trunk group allows DDR call preemption over a voice call per trunk group.

Note If the trunk group channel resource pool is not shared between voice and DDR calls, you should not enable preemption on the trunk group.

The tone timer defines the expiry timer for the preemption tone for the outgoing voice call, which is being preempted by a DDR backup call. When the tone timer expires, the call is disconnected.

Use the following procedure to create a trunk group resource pool and enable preemption on the trunk group.

SUMMARY STEPS

1. enable

2. configure terminal

3. trunk group name

4. preemption enable

5. preemption tone timer seconds

Step 5

preemption tone timer seconds

Example:

Router(config-trunk-group)# preemption tone timer 20

Defines the expiry time for the preemption tone for the outgoing call being preempted by a DDR backup call.

•seconds—Expiry time, in seconds. The range is 4 to 30. The default value is 10.

Note Use the default preemption tone timer command to change back to the default value and no preemption tone timer to disable the tone timer.

Step 6

preemption guard timer value

Example:

Router(config-trunk-group)# preemption guard timer 60

Defines the guard timer for the DDR call to allow time to clear the last call from the channel.

•value—Guard timer, in milliseconds. The range is 60 to 500. When preemption is enabled on the trunk group, the default value is 60.

Defining a Dialer Map Class and Setting the Preemption Level

During dial-on-demand routing (DDR) call setup, an idle B channel is selected from the trunk group. The trunk group and preemption level are configured as part of a map class, which can be attached to a dialer map or dialer string. By default, the preemption level of dialer calls is set to the lowest level (routine) to disable the MLPP service for a DDR call.

Use the following procedure to define a map class for the dialer interface.

•flash-override—Level 0 (highest)

•flash—Level 1

•immediate—Level 2

•priority—Level 3

•routine—Level 4 (lowest)

Note The preemption level flash-override setting can prevent the call to be preempted by a DDR call.

Troubleshooting Tips for Integrated Data and Voice Services

ISDN call failures are most commonly attributed to the following issues:

•Dial-on-demand routing (DDR)

•ISDN layers 1, 2 and 3

•Point-to-Point Protocol (PPP): including link control protocol (LCP), Authentication, or IP Control Protocol (IPCP) related issues.

Use the following commands to troubleshoot integrated data and voice for ISDN interfaces:

•debug dialer events—Used to display debugging information about the packets received on a dialer interface.

•debug isdn q931—Used to check outgoing dial-peer matching for an ISDN incoming call. Enable this command on both sides of the call. The output indicates whether the messages are generated by the calling party router (indicated by TX ->) or by the called party router (indicated by RX <-).

•debug tgrm inout—Used to check voice or DDR channel selection request and return status. From the output, you can determine what type of call enabled the preemption and which timeslot is selected from which trunkgroup.

•debug voip ccapi individual 146—Used to troubleshoot the call control application programming interface (CCAPI) contents. The individual 146 command option is used to log call preemption indication information.

•debug voip ccapi inout—Used to show how a call flows through the system. From the output, you can see the call setup and teardown operations performed on both the telephony and network call legs.

•show call history voice | i Cause—Used to gather DisconnectCause information from the show call history voice command line display.

•show isdn active and show isdn status—Used to show the active data and voice calls.

•show trunk group—Used to check the preemption active or pending calls counter for MLPP preemption calls. The output shows the number of active channels from the trunkgroup and the current preemption levels. If a data call with a higher priority initiates the preemption of voice call, it is shown as pending against the higher priority preemption level.

debug voip ccapi

To troubleshoot the call control application programming interface (CCAPI) contents, use the debug voip ccapi command in privileged EXEC mode. To disable debugging output, use the no form of this command.

debug voip ccapi [all | default | detail | error [call [informational] | software [informational]] | individual range | inout | function | protoheaders | service]

no debug voip ccapi

Syntax Description

all

(Optional) Displays all CCAPI debugging messages.

default

(Optional) Displays CCAPI error and inout information. This option also runs if no keywords are added.

detail

(Optional) Displays CCAPI background messages.

error

(Optional) Displays CCAPI error messages. The debug voip ccapi error command traces the error logs in the call control API. Error logs are generated during normal call processing, if there are insufficient resources, or if there are problems in the underlying network-specific code, the higher call session application, or the call control API itself.

This debug command shows error events or unexpected behavior in system software. Usually no events will be generated.

call

(Optional) Displays call processing errors.

informational

(Optional) Displays minor errors and major errors. Without the informational keyword, only major errors are displayed.

software

(Optional) Displays software errors.

individual

(Optional) Enables individual CCAPI debug outputs.

range

For the individual keyword, the range is an integer value from 1 to 146. For specific range values, see Table 1.

inout

(Optional) Displays CCAPI in/out functions. The debug voip ccapi inout command traces the execution path through the call control API, which serves as the interface between the call session application and the underlying network-specific software. You can use the output from this command to understand how calls are being handled by the router.

This command shows how a call flows through the system. Using this debug level, you can see the call setup and teardown operations performed on both the telephony and network call legs.

function

(Optional) Displays CCAPI function tracing.

protoheaders

(Optional) Displays CCAPI protocol headers passing information.

service

(Optional) Logs debug messages that are not call related.
