Table 10-1 Cisco CallManager Service Parameters 

ParamName
Values
Description

AbleToEstablishMF

Default: T

Used for certification testing. Cisco recommends that you do not change the default value. Valid values are T or F. This setting sends the SABME at startup instead of waiting for the distance end to do it.

AdHocConferenceMixerType

Default: 2

Specifies the mixer type to be used for AdHoc conferences. If the mixer type is set to Unicast Bridge, when a user presses the Conference button on the phone, the conference supplementary service allocates a Unicast Bridge resource to handle the conference.

AdvancedCallForwardHopFlag

Default: F

When AdvancedCallForwardHopFlag = false: When selecting the next voicemail port, the Cisco CallManager call forward feature does not skip the busy or unregistered voicemail port; instead, the call is extended to the busy or unregistered voicemail port, is rejected, and is then forwarded to the next voicemail port.

When AdvancedCallForwardHopFlag = true: When selecting the next voicemail port, the Cisco CallManager call forward feature skips the busy or unregistered voicemail port, the call is extended to the available voicemail port so that the voicemail ports are selected more efficiently.

AlwaysUsePrimeLine

Default: F

T = When phone goes offhook, or the speaker button is pressed, the first line becomes active; but not any additional lines.

Example: If a call comes in on a user's second line, going offhook makes only the first line active. The user must select the second line, in addition to going offhook to answer the call.

AnalogAccessUse729

Default: F

Not supported for Cisco CallManager Release 3.0.

AutoSelectHeldCallFlag

Default: F

Determines whether to automatically select the call on hold when the phone goes offhook if that call was the last signal sent to the phone.

CallAcceptTimer

Default: 10

Specifies the maximum time an application has to accept a call offered at a CTI port or route point.

CallDiagnosticsEnabled

Default: F

Determines whether call diagnostic records are generated. Valid values are

F = not generated

T = generated

Internal to the Cisco AVVID (Architecture for Voice, Video, Integrated Data) system

On the phone

Has Call Waiting enabled

Does not have Forward enabled

CcmPriorityClass

Default: 0

CcmPriorityClass = 0: Cisco CallManager process runs in normal priority class.

CcmPriorityClass = 1: Cisco CallManager process switches between normal and high priority class every second.

CcmPriorityClass = 2: Cisco CallManager process runs in high priority class.

CdrEnabled

Default: F

Determines whether Call Detail Records (CDRs) are generated. Valid values are

T = CDRs are generated

F = CDRs are not generated

CdrLogCallsWithZeroDuration Flag

Default: F

Enables logging of CDR records for calls that never connected or that lasted less than 1second.

ClearCallsWhenDatalinkGoes Down

Default: T

Determines whether calls to the phones terminate if the D-channel (datalink) terminates. Valid values are

0 = Do not clear calls when datalink goes down

1 = Clear calls when datalink goes down

ConnectDisconnectTimer

Default: 7

Used for debugging purposes only. Cisco strongly recommends you do not change the default value. Parameter designates the maximum time allowed for a response from a connect or disconnect request. Valid value is any numeric value.

CtiApplicationHeartBeatTime

Default: 30

Specifies the interval at which CTI sends heartbeat polls to applications.

CTINewCallAcceptTimeout

Default: 4 (seconds)

Specifies timeout interval. Timer ensures that, for calls made into CTI ports and CTI route points, the calls are not suspended, so that callers hear only silence; if the CTI application controlling the CTI ports/route points does not handle the call.

After the Cisco CallManager notifies the application (using JTAPI/TAPI) of an incoming call at a CTI port or CTI route point, the Cisco CallManager waits for a configurable time for the application to handle the call (as in accept, answer, redirect, or disconnect). If the application does not respond within the set time, Cisco CallManager forwards the call to the call forward busy number configured for the CTI port or CTI route point. If no call forward busy is configured, caller receives a fast busy tone.

CTIRequestTimeout

Default: 5 (seconds)

Specifies timeout interval. Timer ensures responses to CTI requests are generated for situations where network or remote Cisco CallManager node problems prevent the normal processing of the CTI requests.

This timer services the following specific CTI requests:

LINE_CALL_INITIATE_REQUEST

CALL_ACCEPT_REQUEST

CALL_ANSWER_REQUEST

CALL_BLIND_TRANSFER_REQUEST

CALL_DISCONNECT_REQUEST

CALL_HOLD_REQUEST

CALL_RETRIEVE_REQUEST

MaxNumberOfStationsIniting

Default: 50

Designates the maximum number of stations that can try to initialize without completing all database requests. Under a heavy load, calls can overwhelm the system to the point where no calls can complete. Set these values to restore usability if the system becomes overwhelmed. Decreasing the LowPriorityQueueThrottlingMaxCount provides faster dial tone but also increases the chances for calls being rejected. Valid value is any numeric value.

MaxStationsInitPerSecond

Default: 10

Parameter is an integer with a value usually between 5 and 15. This parameter throttles the number of phones allowed to concurrently register with Cisco CallManager without being queued.


Note If the performance value is set too high, then phone registrations could slow the Cisco CallManager's real time response. If set too low, the total time for a large group of phones to register will be slow.

Note If you must modify trace parameters, Ciscostrongly recommends doing so from the Trace Configuration page. Refer to the "Configuring Trace" section for more information.


Table 10-3 provides service parameters configured for Cisco Messaging Interface (CMI).

Table 10-3 Cisco Messaging Interface (CMI) Service Parameters 

ParamName
Values
Description

BackupCallManagerName

 

This parameter defines the names of the Cisco CallManagers that are going to be used for the CMI backup. You can use either the name of a Cisco CallManager or its IP address.

BaudRate

Recommended default: 9600

This parameter defines the EIA/TIA-232 connection that Cisco CallManager uses to connect to the voicemail system.


Note Many voicemail systems can be configured to use different baud rates, but the one shown here will frequently be correct.


 

CallManagerName

If the default is left blank, CMI will choose the Cisco CallManager, if existing on a local machine.

This parameter defines the names of the Cisco CallManagers that are going to be used for the primary CMI. You can use either the name of a Cisco CallManager or its IP address.

DataBits

Default: 7

This parameter defines the EIA/TIA-232 connection that Cisco CallManager uses to connect to the voicemail system..

DialingPlan

 

CMI requires this parameter as one of four to register an intercept for the voicemail system with which CMI is going to work.


Note Small systems without a complex dialing plan usually only need the VoiceMailDn parameter. The remaining parameters, DialingPlan, RouteFilter, and VoiceMailPartition, will default to empty strings.


 

InputDnSignificantDigits

Default: 10

This parameter accommodates the differences between voicemailbox numbers and directory numbers (DNs). If a legacy voicemail system has mailbox numbers that are no longer than the DNs on the system, use this parameter to strip the most-significant digits. The numeric value of this parameter indicates how many digits should be used.

KeepAliveDn

None

For this string parameter for most voicemail systems, a value of F is acceptable. However, some Octel systems periodically send an invalid DN specifically for the purpose of verifying that the attached Cisco CallManager is functioning properly. In this case, you can turn off ValidateDns if you know the DN that the Octel system will use as a keepalive one. By programming that DN into the KeepAliveDn parameter, you will ensure that the invalid DN message is returned to the voicemail system when needed.

MwiSearchSpace

 

This parameter designates the search space to use when determining the device to be affected by the MWI lamp.

OutputDnFormat

Default: %010s

Because this parameter is used to format the DNs sent to the voicemail system, most numbers passed to the voicemail system are formatted using this parameter.

OutputExternalFormat

Default: %010s

Because this parameter is also used to format the DNs sent to the voicemail system, most numbers passed to the voicemail system are formatted using this parameter.

Parity

Default: Even

This parameter defines the EIA/TIA-232 connection that CMI uses to connect to the voicemail system.


Note Possible parity settings include None, Even, Odd, Mark, or Space. Settings are usually Even and None, Mark and Space rarely get used. Using just the first character of the parity name also works.


 

RouteFilter

 

CMI requires this parameter as one of four to register an intercept for the voicemail system with which CMI is going to work.


Note Small systems without a complex dialing plan usually only need the VoiceMailDn parameter. The remaining parameters, DialingPlan, RouteFilter, and VoiceMailPartition, will default to empty strings.


 

SerialPort

Default: COM1

This parameter defines the EIA/TIA-232 connection that CMI uses to connect to the voicemail system.


Note Use the SerialPort name that is the same name that you see in Device Manager under NT.


 

SsapiKeepAliveInterval

Default: 30

This numeric parameter specifies keepalive message interval. During normal operations when CMI is attached to a Cisco CallManager, CMI sends a keepalive message to the Cisco CallManager at the rate (in seconds) this parameter specifies.


Note Do not change his parameter from the default value unless directed to do so by the Cisco Technical Assistance Center (TAC).


 

StopBits

Default: 1

This parameter defines the EIA/TIA-232 connection that CMI uses to connect to the voicemail system.

ValidateDns

Default: T

When CMI receives incoming lamp commands from the voicemail system, it normally validates the associated DN against the NumPlan table in an attempt to verify that the DN matches an existing DN known to Cisco CallManager. If the DN is not found in NumPlan, CMI sends an invalid DN message is sent to the voicemailbox.


Note On a system with a lot of traffic to and from the voicemail system, you may choose to skip this validation process by setting the ValidateDns parameter default to F.


 

Refer to the "Configuring Trace" section for descriptive and configuration information on all trace parameters.

VoiceMailDn

 

This parameter represents the voicemail access number.

VoiceMailPartition

 

CMI requires this parameter as one of four to register an intercept for the voicemail system with which CMI is going to work. The voicemail DN resides in this partition.
