Integrated Data and Voice Services for ISDN PRI Interfaces on Multiservice Access Routers
This chapter 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 Integrated Data and Voice Services for ISDN PRI Interfaces
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.
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.
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.
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.
When the isdn integrate calltype allcommand is removed from the interface, the isdn incoming-voice voicesetting is restored and the interface returns to voice mode.
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.
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.
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.
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.
The trunk group preemption level is configured as part of a map class, which can be attached to a dialer map or dialer string.
- For legacy DDR, configure the dialer interface to associate the class parameter with the dialer in-band and dialer map commands.
- For dialer profiles, configure the dialer interface to associate the class parameter with the dialer pool and dialer string commands.
For TDM-only calls, or for calls that are hairpinned, the preemption tone is not heard as the DSPs are dropped. For this reason, you must disable TDM hairpinning on the voice card to use the MLPP DDR backup call preemption feature.
The preemption level of an outgoing voice call is defined from the outbound POTS dial peer. The preemption level defines the preemption priority level of an outgoing voice call.
ISDN call failures are most commonly attributed to dial-on-demand routing (DDR), ISDN layers 1, 2, and 3, and Point-to-Point Protocol (PPP), including link control protocol (LCP), Authentication, or IP Control Protocol (IPCP)-related issues.

- 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.
The figure below shows an ISDN network configured for integrated data and voice services.
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

Troubleshooting Tips for Integrated Data and Voice Services
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.
