12.3(14)T

This command was implemented on the Cisco 2800 series and Cisco 3800 series.

12.4(2)T

This command was integrated into Cisco IOS Release 12.4(2)T.

Usage Guidelines

This command is applied to E&M or Foreign Exchange Station (FXS) interfaces.

For Land Mobile Radio E&M voice ports, the timing hookflash-input command configures the delay between when the M-lead is raised and when voice is transmitted. Setting the hookflash duration to 0 milliseconds specifies no delay in the audio input and eliminates front-end clipping.

Analog phones connected to FXS ports use hookflash to access a second dial tone to initiate some phone features, such as transfer and conference. Hookflash is an on-hook condition of short duration that is usually generated when a phone user presses the Flash button on a phone. Cisco voice gateways measure the duration of detected on-hook conditions to determine whether they should be interpreted as hookflash or not. The duration for the on-hook conditions generated by Flash buttons on phones varies for different phone types and is interpreted by Cisco IOS software as follows:

  • An on-hook condition that lasts for a time period that falls inside the hookflash duration range is considered a hookflash.
  • An on-hook condition that lasts for a shorter period than the lower limit of the range is ignored.
  • An on-hook condition that lasts for a longer period than the higher limit of the range is considered a disconnect.

The hookflash duration range for FXS voice ports is defined as follows:

  • The lower limit of the range is set in software at 150 ms, although there is also a hardware-imposed lower limit that is typically about 20 ms, depending on platform type. An on-hook condition that lasts for a shorter time than this hardware-imposed lower limit is simply not reported to the Cisco IOS software.
  • The upper limit of the range is set in software at 1000 ms by default, although this value can be changed using the timing hookflash-input command in voice-port configuration mode on the voice gateway. The upper limit can be set to any value from 50 to 1550 ms. For more information, see the explanations in the "Examples" section.

This command does not affect whether hookflash relay is enabled; hookflash relay is enabled only when the dtmf-relay h245-signal command is configured on the applicable VoIP dial peers. When the dtmf-relay h245-signal command is configured, the H.323 gateway relays hookflash by using an H.245 "signal" User Input Indication method. Hookflash is sent only when an H.245 signal is available.

Examples

The following example sets an upper limit of 200 milliseconds for the hookflash duration range:

voice-port 1/0/0
 timing hookflash-input 200

If the timing hookflash-input command is set to X, a value greater than 150, then any on-hook duration between 150 and X is interpreted as a hookflash. For example, if X is 1550, the hookflash duration range is 150 to 1550 ms. An on-hook signal that lasts for 1250 ms is interpreted as a hookflash, but an on-hook signal of 55 ms is ignored.

voice-port 1/0/0
 timing hookflash-input 1550

If the timing hookflash-input command is set to X, a value less than 150, then any on-hook duration between Y, the hardware lower limit, and X is interpreted as a hookflash. For example, if X is 65, the hookflash duration range is Y to 65 ms. An on-hook signal that lasts for 1250 ms is interpreted as a disconnect, but an on-hook signal of 55 ms is interpreted as a hookflash. (This example assumes that Y for the voice gateway is lower than 55 ms.)

voice-port 1/0/0
 timing hookflash-input 65

This command was introduced.

Usage Guidelines

This command prevents the voice gateway from prematurely disconnecting private line automatic ring-down (PLAR) off-premises extension (OPX) calls when the duration between ring tones from the switch is more than 6 sec. The absence of a ring tone from the switch indicates that the originating party has disconnected the call. Because some analog switches take longer than 6 sec to generate the ring tone, the voice gateway could clear the call leg while it is still ringing for a PLAR OPX call, unless the 6-sec default is changed with this command.

Examples

The following example sets the timeout for the next ring to 8 sec:

voice-port 2/0/10

This command was integrated into Cisco IOS Release 12.3(14)T.

12.4(12)

This command was integrated into Cisco IOS Release 12.4(12).

Usage Guidelines

Prior to the implementation of the timing sup-disconnect command, analog Foreign Exchange Office (FXO) ports could not detect short disconnect signals lasting fewer than 350 ms in duration. Using this command, you can specify a wait period from 50 to 1500 ms to ensure that when an on-hook indication persists for a time that is longer than the configured value, the on-hook condition is considered intentional and a hang-up is signaled on the POTS call leg.

This timer affects only analog loop-start FXO voice ports.

Even though the timing sup-disconnect command can be entered under the voice port in FXO ground-start signaling, the changes in the timer setting take effect only in FXO loop-start signaling.

Examples

The following example sets the timer to wait 500 ms after detecting an on-hook signal before a supervisory disconnect occurs on the POTS call leg:

voice-port 1/0/0
 timing sup-disconnect 500

12.4(13)

This command was integrated into Cisco IOS Release 12.4(13) and the receive keyword and minimum and maximum arguments were added.

Usage Guidelines

The call signal direction for the timing wink-duration command is out. This command is supported on ear and mouth (E&M) ports only.

When wink-start signaling is used, the originating side seizes the line by going off-hook and then waits for an acknowledgment from the other end before initiating a call. The acknowledgment is a reversal of polarity (off-hook) for a timing period referred to as a wink. A wink should occur no earlier than 100 ms after the receipt of the incoming seizure signal. In addition to the signaling function, the wink start serves as an integrity check that identifies a malfunctioning trunk and allows the network to send a reorder tone to the calling party.

When you set the receive range, the minimum and maximum values of acceptable wink must provide an acceptable range of at least 50 ms. For example, entering the command timing wink-duration receive 160 200 results in an error message.

Examples

The following example shows how to set the transmit wink-signal duration on voice port 1/0/0 to 300 ms:

voice-port 1/0/0
 timing wink-duration 300

The following example shows how to set the range for the receive wink-signal duration on voice port 1/0/0 to 160 to 210 ms:

voice-port 1/0/0

Usage Guidelines

This command changes the value of the FAC for Toggle Between Two Calls from the default (#5) to the specified value.

If you attempt to configure this command with a value that is already configured for another FAC in feature mode, you receive a message. This message will not prevent you from configuring the feature code. If you configure a duplicate FAC, the system implements the first feature it matches in the order of precedence as determined by the value for each FAC (#1 to #5).

If you attempt to configure this command with a value that precludes or is precluded by another FAC in feature mode, you receive a message. If you configure a FAC to a value that precludes or is precluded by another FAC in feature mode, the system always executes the call feature with the shortest code and ignores the longer code. For example, 1 will always preclude 12 and 123. These messages will not prevent you from configuring the feature code. You must configure a new value for the precluded code in order to enable phone user access to that feature.

Examples

The following example shows how to change the value of the feature code for the Toggle Between Two Calls feature from the default (#5). With this configuration, a phone user in basic call mode presses hook flash to get the first dial tone, then dials an extension number to connect to a second call. During the second call, the user presses a hook flash to get a feature tone and then dials 55 to toggle back to the previous call party.

Router(config)# stcapp call-control mode feature
Router(config-stcapp-fmcode)# toggle-between-two-calls 55

This command was introduced.

Usage Guidelines

Use this command in voice-service VoIP or VoIP dial-peer configuration mode to activate detection of all ANS, ANSam, and ANSpr tones and enable or disable echo canceller control. When this command is issued in voice-service VoIP configuration mode, all dial peers are globally configured unless a specific dial peer is configured for no tone incoming.

To deactivate all 2100-Hz ANS, ANSam, and ANSpr tone detection on either the IP or the PSTN side of the network, and enable the echo canceller, use the no tone incoming command in voice-service VoIP configuration or VoIP dial-peer configuration mode.

If neither IP nor PSTN is specified, all ANS, ANSam, and ANSpr tones are detected on both sides of the network, and the echo suppressor is disabled in all cases.

The tone incoming ip ans-all auto-control command is equivalent to these two commands together:

  • tone incoming ip ans disable echo suppressor
  • tone incoming ip anspr disable echo suppressor

The tone incoming pstn ans-all auto-control command is equivalent to these two commands together:

  • tone incoming pstn ans disable echo suppressor
  • tone incoming pstn anspr disable echo suppressor

The tone incoming ans-all auto-control command is equivalent to these four commands together:

  • tone incoming ip ans disable echo suppressor
  • tone incoming ip anspr disable echo suppressor
  • tone incoming pstn ans disable echo suppressor
  • tone incoming pstn anspr disable echo suppressor

When modem tones from either the IP or PSTN direction are received, the echo canceller can be dynamically disabled to allow modem calls to pass through.

The IP tone detector feature applies only on the following NextPort platforms: Cisco AS5350, Cisco AS5400, and Cisco AS5850--and only with SIP and H.323 voice signaling. It does not apply to MGCP in VoIP dial-peer configuration mode.

The gateway must be configured for G.711 codecs for the IP tone detector feature to work (see the "Examples" section).

To display the status of the echo canceller, use the show port operational status command.

Examples

The following example configures tone detection of ANS tones in voice-service VoIP configuration mode:

Router(conf-voi-serv)# tone incoming ip ans disable echo supressor

The following example configures tone detection of all incoming ANS, ANSam, and ANSpr tones on a dial peer:

Router(config-dial-peer)# tone incoming ip ans-all auto-control

Syntax Description

keypad-character

Character string of one to four characters that can be dialed on a telephone keypad (0-9, *, #). Default is #2.

Command Default

The default value is #2.

Command Modes


STC application feature-mode call-control configuration (config-stcapp-fmcode)

Command History

Release

Modification

15.0(1)M

This command was introduced.

Usage Guidelines

This command changes the value of the FAC for Call Transfer from the default (#2) to the specified value.

If you attempt to configure this command with a value that is already configured for another FAC in feature mode, you receive a message. This message will not prevent you from configuring the feature code. If you configure a duplicate FAC, the system implements the first feature it matches in the order of precedence as determined by the value for each FAC (#1 to #5).

If you attempt to configure this command with a value that precludes or is precluded by another FAC in feature mode, you receive a message. If you configure a FAC to a value that precludes or is precluded by another FAC in feature mode, the system always executes the call feature with the shortest code and ignores the longer code. For example, 1 will always preclude 12 and 123. These messages will not prevent you from configuring the feature code. You must configure a new value for the precluded code in order to enable phone user access to that feature.

Examples

The following example shows how to change the value of the feature code for the Call Transfer feature from the default (#2). With this configuration, a phone user presses hook flash to get the first dial tone, then dials an extension number to connect to a second call. When the second call is established, the user presses hook flash to get a feature tone and then dials 22 to transfer the call; the user hears silence after the call is transferred.

Router(config)# stcapp call-control mode feature
Router(config-stcapp-fmcode)# transfer 22
Router(config-stcapp-fmcode)# exit

Command History

Release

Modification

12.3(8)T

This command was introduced.

Usage Guidelines

Switching between transports is provided globally on the router and also on an individual VoIP dial peer.

  • Dial-peer mode. You can configure transport for a specific dial peer by using the voice-class sip transport switchcommand. The voice-class sip transport switch command in dial-peer configuration mode takes precedence over the transport switchcommand in global configuration mode.
  • SIP mode. You can configure transport globally by using the transport switchcommand. The transport switch command is considered only when there is no matching VoIP dial peer.

In a call forking scenario, if this command is configured, the configuration applies to all forks.

Examples

The following example enables switching of the transport from UDP to TCP:

Router(config)# voice service voip
Router(config-voi-srv)# sip
Router(conf-serv-sip)# transport switch udp tcp

Related Commands

Command

Description

debug ccsip transport

Enables tracing of the SIP transport handler and the TCP or UDP process.

Command History

Release

Modification

12.1(3)T

This command was introduced.

Usage Guidelines

Use the trunk group command to assign a number or a name to a set of trunk characteristics. The set of characteristics, or profile , is assigned to specific trunks as part of the usual trunk configuration steps.

The trunk group command initiates the profile definition and switches from global configuration to trunk group configuration mode. Additional commands are available to construct the characteristics of the profile.

Up to 1000 trunk groups can be configured on the gateway provided that the gateway has sufficient memory to store the profiles. If you see the message "Trunk group name could not be added as the threshold has been reached", enter the debug tgrmcommand and check the number of trunk groups or check for insufficient memory.

To associate a trunk group with an interface, use the trunk-group (interface) command. A trunk group that was created using the trunk group (global) command can be associated with an interface. However, a trunk group need not be defined globally before being associated with an interface. If a trunk group has not been defined globally, it will be created by issuing the trunk-group (interface) command.

Examples

The following example creates trunk group 5 and configures the trunk group profile:

Router(config)# trunk group 5
Router(config-trunk-group)# carrier-id allcalls
Router(config-trunk-group)# max-calls voice 500 in
Router(config-trunk-group)# hunt-scheme round-robin even up
Router(config-trunk-group)# translation-profile incoming 3
Router(config-trunk-group)# translation-profile outgoing 2
Router(config-trunk-group)# exit

The following example creates a trunk group named "mytrunk" and configures the trunk group profile:

Router(config)# trunk group mytrunk
Router(config-trunk-group)# carrier-id local
Router(config-trunk-group)# max-calls voice 500

Usage Guidelines

Use the trunk-group command to assign a CAS trunk as a member of a trunk group. This assignment provides the CAS trunk with carrier information, a hunt scheme for finding an available channel for the outgoing call, and translation profiles for number translation.

If more than one CAS trunk is assigned to the same trunk group, the preference-num value determines the order in which the trunk group uses the interfaces. A preference-num value of 1 is the highest preference so that the trunk is used first; a value of 64 is the lowest preference so that the trunk is used last. If no value is entered for preference-num, the software assigns the trunk a preference of 65, which causes that trunk to be used after all other trunks are used.

If two CAS trunks have the same preference-num, the trunk that was configured first is used before the other trunk.

A CAS trunk can belong to only one trunk group.

If an interface is removed from the CAS trunk, the interface is removed automatically from the trunk group. A new nonprimary CAS interface is automatically a member of the same trunk group as its primary CAS interface.

Examples

The following example assigns two CAS interfaces to trunk group "westcoast". The preference value for DS0 group 2 is lower than for DS0 group 1; hence DS0 group 2 has a higher priority. Trunk group "westcoast" uses DS0 group 2 first.

Router(config)# controller T1 1/0
Router(config-controller)# ds0-group 1 timeslots 1-10 type e&m-fgd
Router(config-controller)# cas-custom 1
Router(config-controller)# trunk-group westcoast 5

12.2

This command was integrated into the Cisco IOS Release 12.2.

12.2(11)T

Thepreference -num argument was added.

Usage Guidelines

Use the trunkgroup command to assign an outgoing dial peer as a member of one or more trunk groups. This assignment provides the dial peer with carrier information, a hunt scheme for finding an available channel for the outgoing call, and translation profiles for number translation.

If the dial peer is a member of more than one trunk group, use the preference-num value to set the order in which the trunk groups will be used for the dial peer. A preference-num value of 1 is the highest preference so that the trunk group is used first; a value of 64 is the lowest preference so that the trunk group is used last. If no value is entered for preference-num, the software assigns the trunk group a preference of 65, which causes that trunk group to be selected after all other trunks are used.

If two trunk groups have the same preference-num, the trunk group that was configured first is used before the other trunk group.

Examples

In the following example, dial peer 112 should use the trunk group "east17" and trunk group "north5" for outbound dial peer matching. When selecting a trunk group, "north5" is used first because it has a higher preference than "east17":

Router(config)# dial-peer voice 112 pots
Router(config-dial-peer)# trunkgroup east17 3
Router(config-dial-peer)# trunkgroup north5 1

The trunk-group identification was expanded to include alphanumeric characters using the name argument, and the preference-num argument was added.

Usage Guidelines

Use the trunk-group command to configure an ISDN PRI or Non-Facility Associated Signaling (NFAS) interface as a member of a trunk group. This assignment provides the interface with carrier information, a hunt scheme for finding an available channel for the outgoing call, and translation profiles for number translation.

If more than one interface is assigned to the same trunk group, the preference_num value determines the order in which the trunk group uses the interfaces. A preference-num value of 1 is the highest preference so that the interface is used first; a value of 64 is the lowest preference so that the interface is used last. If no value is entered for preference-num, the software assigns the interface a preference of 65, which causes that interface to be selected after all other interfaces are used.

If two interfaces have the same preference-num, the interface that was configured first is used before the other interface.

An interface can belong to only one trunk group. Multiple interfaces can belong to the same trunk group.

If an NFAS interface group is assigned as a member of a trunk group, all the subinterfaces belong to that trunk group.

If a subinterface is removed from the NFAS group, the subinterface is removed automatically from the trunk group.

If a new nonprimary NFAS interface is added to the NFAS group, that interface automatically becomes a member of the same trunk group as its primary NFAS interface.

Examples

The following example assigns an ISDN interface to trunk group "eastern" with a preference of 3.

Router(config)# interface Serial2:23
Router(config-if)# no ip address
Router(config-if)# isdn switch-type primary-ni
Router(config-if)# isdn T306 30000
Router(config-if)# isdn T310 10000
Router(config-if)# no cdp enable
Router(config-if)# trunk-group eastern 3
Router(config-if)# exit

If another interface were assigned to trunk group "eastern" with preference of 1 or 2, the trunk group would use that interface before the one shown above.

If more than one voice port is assigned to the same trunk group, the preference-num value determines the order by which the trunk group uses the voice ports. A preference-num value of 1 is the highest preference so that the voice port is used first; a value of 64 is the lowest preference so that the voice port is used last. If no value is entered for preference-num, the software assigns the voice port a preference of 65, which causes that voice port to be selected after all other voice ports are used.

If two voice ports have the same preference-num, the voice port that was configured first is used before the other voice port.

A voice port can belong to only one trunk group. Multiple voice ports can belong to the same trunk group.

Examples

The following example assigns voice port 1/0/0 and voice port 1/0/1 to trunk group "north5". Trunk group "north5" uses voice port 1/0/1 before using voice port 1/0/0 because voice port 1/0/1 has preference 1, which is a higher priority than voice port 1/0/0, with preference 2.

Router(config)# voice port 1/0/0

Usage Guidelines

An originating gateway uses the source trunk group label as a matching key to route the call over an inbound dial peer. The terminating gateway uses the target trunk group label to select a dial peer for routing the outbound call over a POTS line.

If a dial peer has a source (or target) carrier ID already defined, then assigning a source (or target) trunk group label to that same dial peer overrides the source (or target) carrier ID. The same is true for the reverse: if a dial peer has a source (or target) trunk group label defined, then assigning a source (or target) carrier ID for that same dial peer overrides the source (or target) trunk group label.

The name of a trunk group label and carrier ID cannot be the same in dial peers.

Examples

The following example shows that dial peer 112 should use trunk group label "north3" for inbound dial peer matching and trunk group label "east17" for outbound dial peer matching:

Router(config)# dial-peer voice 112 pots
Router(config-dial-peer)# trunk-group-label source north3

Usage Guidelines

A terminating gateway uses the source trunk group label as a search key to find a source IP group for the incoming VoIP call. The gateway uses the target trunk group label to select an outbound dial peer to route the call over a POTS line.

If a source IP group has a source (or target) carrier ID already defined, then assigning a source (or target) trunk group label to that same source IP group overrides the source (or target) carrier ID. The same is true for the reverse: if a source IP group has a source (or target) trunk group label defined, then assigning a source (or target) carrier ID for that same source IP group overrides the source (or target) trunk group label.

The name of a trunk group label and carrier ID of the same type (source or target) cannot be the same in the source IP group.

Examples

The following example shows that source IP group "alpha" uses trunk group "north3" to search for a source IP group for incoming VoIP calls and trunk group "east17" for outbound dial peer matching:

Router(config)# voice source-group alpha
Router(cfg-source-grp)# trunk-group-label source north3

11.3(1)T

This command was introduced on Cisco 3600 series routers.

11.3(1)MA

This command was implemented on Cisco MC3810.

Usage Guidelines

Use the type command to specify the E&M interface for a particular voice port. With 1, the tie-line equipment generates the E-signal to the PBX type grounding the E-lead. The tie-line equipment detects the M-signal by detecting current flow to ground. If you select 1, a common ground must exist between the line equipment and the PBX.

With 2, the interface requires no common ground between the equipment, thereby avoiding ground loop noise problems. The E-signal is generated toward the PBX by connecting it to SG. The M-signal is indicated by the PBX connecting it to SB. While Type 2 interfaces do not require a common ground, they do have the tendency to inject noise into the audio paths because they are asymmetrical with respect to the current flow between devices.


Note


E&M Type 4 is not a supported option. However, Type 4 operates similarly to Type 2 except for the M-lead operation. On Type 4, the M-lead states are open/ground, compared to Type 2, which is open/battery. Type 4 can interface with Type 2. To use Type 4 you can set the E&M voice port to Type 2 and perform the necessary M-lead rewiring.


With 3, the interface operates the same as Type 1 interfaces with respect to the E-signal. The M-signal, however, is indicated by the PBX connecting it to SB on assertion and alternately connecting it to SG during inactivity. If you select 3, a common ground must be shared between equipment.

With 5, the Type 5 line equipment indicates E-signal to the PBX by grounding the E-lead. The PBX indicates M-signal by grounding the M-lead. A Type 5 interface is quasi-symmetrical in that while the line is up, current flow is more or less equal between the PBX and the line equipment, but noise injection is a problem.

Examples

The following example selects Type 3 as the interface type for the voice port:

voice-port 1/0/0
 type 3
