Modification

11.3(1)MA

This command was introduced on Cisco MC38310.

12.1(1)T

This command was modified to include voice WAN interface cards (VWICs) for Cisco 2600 series and Cisco 3600 series.

12.1(2)T

This command was modified for the OC-3/STM-1 ATM Circuit Emulation Service network module on Cisco 2600 series and Cisco 3600 series.

Usage Guidelines

The tdm-group command allows specific timeslots to switch from port 0 to port 1 and vice versa. This command is similar to the channel-group command, but it does not create a serial interface to terminate the specified channels.


Note


Channel groups, CAS voice groups, DS0 groups, and TDM groups all use group numbers. All group numbers configured for channel groups, CAS voice groups, DS0 groups, and TDM groups must be unique on the local router. For example, you cannot use the same group number for a channel group and for a TDM group.


Examples

The following example configures TDM group 1 to include timeslots 13 through 20:

controller T1 1
 tdm-group 1 timeslots 13-20

The following example configures TDM group number 20 on controller T1 1 to support Foreign Exchange Office (FXO) ground-start:

controller T1 1
 tdm-group 20 timeslot 20 type fxs ground-start

tech-prefix

To specify that a particular technology prefix be prepended to the destination pattern of a specific dial peer, use the tech-prefix command in dial peer configuration mode. To disable the defined technology prefix for this dial peer, use the no form of this command.

tech-prefix number

no tech-prefix

Syntax Description

number

Defines the numbers used as the technology prefix. Each technology prefix can contain up to 11 characters. Although not strictly necessary, a pound (#) symbol is frequently used as the last character in a technology prefix. Valid characters are 0 though 9, the pound (#) symbol, and the asterisk (*).

Command Default

No technology prefix is defined.

Modification

11.3(6)NA2

This command was introduced on Cisco 2600 series and Cisco 3600 series.

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

Technology prefixes are used to distinguish between gateways that have specific capabilities within a given zone. In the exchange between the gateway and the gatekeeper, the technology prefix is used to select a gateway after the zone has been selected. Use the tech-prefix command to define technology prefixes.

Technology prefixes can be used as a discriminator so that the gateway can tell the gatekeeper that a certain technology is associated with a particular call (for example, 15# could mean a fax transmission), or a technology prefix can be used like an area code for more generic routing. No standard defines what the numbers in a technology prefix mean; by convention, technology prefixes are designated by a pound (#) symbol as the last character.

In most cases, there is a dynamic protocol exchange between the gateway and the gatekeeper that enables the gateway to inform the gatekeeper about technology prefixes and where to forward calls. If, for some reason, that dynamic registry feature is not in effect, you can statically configure the gatekeeper to query the gateway for this information by configuring the gw-type-prefix command on the gatekeeper. Use the show gatekeeper gw-type-prefix commandto display how the gatekeeper has mapped the technology prefixes to local gateways.


Note


Cisco gatekeepers use the asterisk (*) as a reserved character. If you are using Cisco gatekeepers, do not use the asterisk as part of the technology prefix.


Examples

The following example defines a technology prefix of 14# for the specified dial peer. In this example, the technology prefix means that the H.323 gateway asks the RAS gatekeeper to direct calls using the technology prefix of 14#.

dial-peer voice 10 voip
 destination-pattern 14...
 tech-prefix 14#

Command History

Release

Modification

12.4(22)YB

This command was introduced.

15.0(1)M

This command was integrated into Cisco IOS Release 15.0(1)M.

Usage Guidelines

The voice-class tel-config to-hdrcommand takes precedence over the tel-config to-hdr command configured in SIP configuration mode. However, if the voice-class tel-config to-hdr command is configured with the system keyword, the gateway uses the global settings configured by the tel-config to-hdr command.

Enter SIP configuration mode after entering voice-service VoIP configuration mode, as shown in the "Examples" section.

Examples

The following example configures the To: header in TEL format, and appends the phone-context parameter to the header:

voice service voip
sip
 tel-config to-hdr phone-context

Usage Guidelines

This command enters the telephony-service configuration mode for configuring system wide parameters for SCCP IP phones in Cisco Unified CME.


Note


The voice-gateway system is tied to the telephony service. The telephony-service command must be configured before the voice-gateway system is configured; otherwise, the voice gateway is hidden from the user.


Use the setup keyword to start the interactive setup tool to automatically configure only Cisco Unified IP Phone 7910s, 7940s, and 7960s in Cisco Unified CME.

For alternate methods of automatically configuring Cisco Unified CME, including Cisco Unified IP Phone 7910s, 7940s, and 7960s and other Cisco Unified IP phones, see the Cisco Unified CME Administrator Guide.

The setup keyword is not stored in the router nonvolatile random-access memory (NVRAM).

If you attempt to use the setup option for a system that already has a telephony-service configuration, the command is rejected. To use the setup option after an existing telephony-service configuration has been created, first remove the existing configuration using the no telephony-service command.

The table below shows a sample dialog with the Cisco CME setup tool and explains possible responses to the Cisco CME setup tool prompts.

Table 1 Cisco CME Setup Tool Dialog Prompts

Cisco CME Setup Tool Prompt

Description

Do you want to setup DHCP service for your IP phones? [yes/no]:
If you respond yes, you see the following prompts:
IP network for telephony-service DHCP  Pool:
Subnet mask for DHCP network : 
TFTP Server IP address (Option 150) :
Default Router for DHCP Pool :
  • Yes--Configures the Cisco Unified CME router to act as a Dynamic Host Configuration Protocol (DHCP) server, automatically providing IP addresses to your IP phones and provisioning the default gateway and TFTP IP addresses to be used by the phones. This method creates a single pool of IP addresses. If you need a pool for non-IP phones or if the Cisco router cannot act as the DHCP router, answer no and manually define the DHCP server.
  • No--Indicates that you have already configured DHCP or static IP addresses for the IP phones.
Do you want to start telephony-service setup? [yes/no]:
  • Yes-- Starts the interactive setup tool for configuring Cisco Unified IP Phone 7910s, 7940s, and 7960s.
  • No --Terminates the Cisco CME setup tool.
Enter the IP source address for Cisco CallManager Express:
Enter the Skinny Port for Cisco CallManager Express:  [2000]:

IP address on which the router provides Cisco Unified CME services, usually the default gateway for the IP subnet that you are using for the IP phones, and the port for Skinny Client Control Protocol (SCCP) messages.

How many IP phones do you want to configure : [0]:

Enter the maximum number of IP phones that this Cisco Unified CME system will support. This number can be increased later, to the maximum allowed for this version and your router.

Note   

The Cisco CME setup tool associates one number with each newly registering phone. You can manually add additional numbers on a phone at a later time.

Do you want dual-line extensions assigned to phones? [yes for dual-line / no for single-line]:
  • Yes --Each newly registering IP phones is assigned a single number that is associated with a single phone button. The system generates a dual-line ephone-dn entry for each ephone-dn.
  • No --IP phones are linked directly to one or more PSTN trunk lines. Using keyswitch mode requires manual configuration in addition to using the Cisco CME setup tool. The system generates two ephone-dn entries for each ephone-dn, and they are both assigned to a single phone.

  • Starting with this number, remaining extension numbers are automatically configured in a contiguous manner.
  • This number must be compatible with your telephone number plan, and, if you use Direct Inward Dialing (DID) service, with public switched telephone network (PSTN) numbering requirements.
Do you have Direct-Inward-Dial service for all your phones? [yes/no]:
  • Yes--If you have trunk access to public telephone service by ISDN or VoIP for all extension numbers. The system creates an appropriate dial plan.
  • No--If you have simple analog phone lines only (for example, foreign exchange office [FXO] interfaces) or if you have trunk access for some lines but not all lines.

If you answer yes to the previous question, you see the following prompt:

This command was introduced.

Usage Guidelines

Use this command in voice-service configuration mode to enable text relay globally for H.323, Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP), and Media Gateway Control Protocol (MGCP). A global configuration is the system-wide configuration that is applied to any VoIP call on the gateway.

Use this command in dial peer voice configuration mode to enable text relay for calls that match a specific dial peer. The dial peer voice configuration takes precedence over the global configuration.

Examples

The following example shows how to enable text relay for all VoIP calls on the gateway:

Router(config)# voice service voip
Router(config-voi-serv)# text relay protocol cisco

The following example shows how to enable text relay for calls that match a specific dial peer:

Router(config)# dial-peer voice 2000 voip
Router(config-dial-peer)# text relay protocol cisco

Usage Guidelines

When using the text relay rtp command, you can either configure the payload-type, or the redundancy level, or both.

  • Use this command in voice service configuration mode to set the RTP payload type and redundancy level globally for H.323, Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP), and Media Gateway Control Protocol (MGCP). A global configuration is the system-wide configuration that is applied to any VoIP call on the gateway.
  • Use this command in dial-peer configuration mode to set the RTP payload type and redundancy level for calls that match a specific dial peer. The dial peer voice configuration takes precedence over the global configuration.

Examples

The following example shows how to globally configure text relay RTP payload type 117 and redundancy level 2:

Router(config)# voice service voip
Router(config-voi-serv)# text relay rtp payload-type 117 redundancy 2

The following example shows how to configure the default text relay RTP payload type and redundancy level 1 for calls that match a specific dial peer:

Router(config)# dial-peer voice 2000 voip
Router(config-dial-peer)# text relay rtp payload-type default redundancy 1

Modification

12.3(1)

This command was introduced.

Usage Guidelines

The E. 164 address family is used if the telephony network is a public telephony network. Decimal and pentadecimal options can be used to advertise private dial plans. For example if a company wants to use TRIP in within their enterprise telephony network using 5-digit extensions, then the gateway would advertise the beginning digits of their private numbers as a decimal address family. These calls cannot be sent out of the company’s private telephony network because they are not E.164-compliant.

The pentadecimal family allows numbers 0 through 9 and alphabetic characters A through E and can be used in countries where letters are also carried in the called number.

Examples

The following example shows that POTS dial peer 10 has the address family set for E.164 addresses:

Router(config)# dial-peer voice pots 10
Router(config-dial-peer)# tgrep address family e164

Usage Guidelines

When only tgrep advertise is entered, the dial peer is advertised without any other attribute.

When no tgrep advertise is used on the dial peer, the dial peer inherits the attributes set in the global advertise command.

When the global no advertise command is used, it forbids advertisement of that particular address family altogether. The tgrep advertise command has no effect until the advertisement of the address family is enabled globally.

Examples

The following example shows a TGREP advertisement that sends call success rate, available circuits, total circuits, and carrier address family attribute information:

Router(config)# dial-peer voice pots 10
Router(config-dial-peer)# tgrep advertise csr ac tc carrier

To turn on the advertisement of this trunk group for resource availability and other carrier information, use the tgrep advertise command in trunk group configuration mode. To turn off local trunk group advertisement and use the global setting, use the no form of this command.

tgrep advertise [csr] [ac] [tc] [disable]

no tgrep advertise [csr] [ac] [tc] [disable]

Syntax Description

Command History

Release

Modification

12.3(1)

This command was introduced.

Usage Guidelines

When only tgrep advertise is entered, the trunk group is advertised without any other attribute. When no tgrep advertise is used, the trunk group uses the global setting configured with the advertise command in TGREP configuration mode. To turn off advertisement of this trunk group, the disable keyword should be used.

There is a subtle difference between the no form of this command and the no form of the global advertise command. When no tgrep advertise is used on the trunk group, the trunk group inherits the attributes set in the global advertise command.

When the global no advertise command is used, it forbids advertisement of that particular address family altogether. The tgrep advertise command has no effect until the advertisement of the address family is enabled globally.

When the carrier keyword is used, the carrier defined under the trunk group assumes the configuration. Because multiple trunk groups can have the same carrier defined, the same configuration will show up under all trunk groups that have the same carrier defined. When the no tgrep advertise carrier command is used to revert to the global carrier configuration for the carrier under this trunk group, the same will happen to all the trunk groups who have the same carrier defined under them.


Note


This command overrides the attributes set for advertisement using the global advertise (tgrep) command.


Examples

The following example shows that trunk group 101 has been configured to send a TGREP advertisement that sends call success rate, available circuits, total circuits, and prefix attribute information:

Router(config)# trunk group 101
Router(config-dial-peer)# tgrep advertise csr ac tc carrier

12.2(13b)

This command was introduced on the following platforms: Cisco 1700 Cisco 1751, Cisco 2600 (with and without the NM-HDA), Cisco 3600 (with and without the NM-HDA), Cisco 7200 (with and without the NM-HDA), Cisco AS5300, Cisco AS5800, and Cisco MC3810.

12.2(16)

This command was integrated into Cisco IOS Release 12.2(16).

Usage Guidelines

Cisco voice activity detection (VAD) has two layers: application programming interface (API) layer and processing layer. There are 3 states that the processing layer classifies incoming signals: speech, unknown, and silence. The state of the incoming signals is determined by the noise threshold.

In earlier Cisco IOS releases, the noise threshold is fixed between -62 dB and -78 dB. If the voice level is below the noise threshold, then the signal is classified as silence. If the incoming signal cannot be classified, the variable thresholds that are computed with the statistics of speech and noise that VAD gathers is used to make a determination. If the signal still cannot be classified, then it is marked as unknown. The final decision is made by the API. For applications such as hoot-n-holler, you could have the noise create unwanted spurious packets (for example, a voice stream) taking up bandwidth.

With Cisco IOS Release 12.2(16), the noise threshold is configurable using the threshold noise command.

Examples

The following sample configuration shows a noise threshold level of -50 dB:

voice-port 1/0/0
 threshold noise -50

Usage Guidelines

The timeout ptt command is available on an ear and mouth (E&M) analog or digital voice port only if the signal type for that port is Land Mobile Radio (LMR). The purpose of this command is to limit extended radio transmission. When the time limit configured with this command expires, the radio transmitter unkeys, so that listeners on the channel cannot hear the speaker, even if the speaker continues to talk. When the speaker unkeys the radio, the timer is reactivated.

12.2(4)T

This command was integrated into Cisco IOS Release 12.2(4)T.

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command is used when configuring values for a Media Gateway Control Protocol (MGCP) profile.

The interdigit timer is used when matching a digit map, which is a representation of the number and type of digits that a gateway can expect to collect in a buffer, based on the network dial plan. The interdigit timer is started when the first digit is entered and is restarted after each new digit is entered, until a digit map match or mismatch occurs.

The interdigit timer takes on one of two values, T(partial) or T(critical). When at least one more digit is required to make a match to any of the patterns in the digit map, the value of T(partial) is used for the timer. If a timer is all that is required to produce a match according to the digit map, T(critical) is used for the timer.

When the interdigit timer is used without a digit map, it takes on the value T(critical). It is started immediately and is simply canceled (but not restarted) as soon as a digit is entered.

Examples

The following example sets the T(critical) value to 15 seconds:

Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tcrit 15

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command is used when configuring values for a Media Gateway Control Protocol (MGCP) profile.

When a gateway recognizes that an endpoint has lost its communication with the call agent (has become disconnected) , a timer known as the disconnected timer is initialized to a random value between 0 and the disconnected initial waiting delay (Tdinit), which is configured with the timeout tdinit command. The gateway then waits for one of three things: the end of this timer, the reception of a command from the call agent, or the detection of local user activity for the endpoint, such as an off-hook transition. When one of the first two cases occurs, the gateway initiates the disconnected procedure for that endpoint. In the third case, the detection of local user activity, a minimum waiting delay (Tdmin) also must have elapsed. This value is configured with the timeout tdmin command.

The disconnected procedure consists of the endpoint sending a RestartInProgress (RSIP) message to the call agent, stating that it was disconnected and is now trying to reestablish connectivity.

If the disconnected procedure is unsuccessful and the endpoint is still disconnected, the disconnected timer is doubled; this process is repeated until the timer value reaches the maximum waiting delay (Tdmax), which is configured with the timeout tdmax command.

Examples

The following example sets the initial waiting delay value (Tdinit) to 25 seconds:

Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tdinit 25

Usage Guidelines

This command is used when configuring values for a Media Gateway Control Protocol (MGCP) profile.

MGCP messages are carried over User Datagram Protocol (UDP), and are therefore subject to packet loss. When a response to a message is not received promptly, the sender retransmits the message. The gateway keeps in memory a list of the responses it has sent for the number of seconds in the Thist timeout value. The gateway also keeps a list of the messages currently being processed, with their transaction identifiers, to prevent processing or acknowledging the same message more than once.

The following example sets the packet storage timeout value (Thist) to 15 seconds:

Router(config)# mgcp profile nyc-ca

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command is used when configuring values for a Media Gateway Control Protocol (MGCP) profile.

The gateway uses the continuity2 (cot2) tone timeout value when the call agent does not provide a timeout value associated with the request to generate a cot2 tone signal.

Continuity1 and continuity2 tone signals are used in Integrated Services Digital Networks User Part (ISUP) calls to determine that a call path has been established before connecting a call. The call agent is provisioned to know which test to apply to a given endpoint.

Examples

The following example sets the continuity2 tone timeout value to 50 seconds:

Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tone cot2 50

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command is used when configuring values for a Media Gateway Control Protocol (MGCP) profile.

The interdigit timer is used when matching digit maps. It is started when the first digit is entered, and is restarted after each new digit is entered, until a digit map match or mismatch occurs.

The interdigit timer takes on one of two values, T(partial) or T(critical). When at least one more digit is required to make a match to any of the patterns in the digit map, the value of T(partial) is used for the timer. If a timer is all that is required to produce a match according to the digit map, T(critical) is used for the timer.

When the interdigit timer is used without a digit map, it takes on the value T(critical). It is started immediately and is simply canceled (but not restarted) as soon as a digit is entered.

Examples

The following example sets the partial timeout value to 15 seconds:

Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tpar 15
