The Application Server object is a child of the Global Application Servers object. It defines an external computer, connected to the MetaSwitch NE using SIP, which provides call services to MetaSwitch subscribers.
Parameter |
Access |
Description |
Directory number | Create | The directory number (full national telephone number including the leading zero) used by the NE to access this server. Either type in the number (noting that the directory number must be within an active Number Range), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use.
If you click on the ellipsis symbol, the dialog box that appears displays a list of configured Number Ranges. Select the Number Range from which the new subscriber's number should be taken and click on Next.
The next dialog box offers 'manual selection' or 'automatic selection'.
|
Description | Change | Unique user-friendly name identifying the Application Server. Specify a name of up to 64 characters. If a name is not specified, the EMS displays a default. |
Configured SIP Binding | Change Inactive | Specifies the configured SIP binding that this Application Server uses to connect to the NE. To specify a configured SIP binding, click on the search button at the end of the field to select from a list of configured SIP bindings for which the Usage field is set to Application Server. As a short-cut to select the Configured SIP Binding, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. For more details, refer to the description of the Details panel in Operations Manual: Overview. |
Server type | Change Inactive | The services that this server provides. Select one or more of the following values.
|
Action on failure | Change Inactive | The action that the NE should take if a call to the server fails. This applies if the server fails after the call has been connected to it, if the server does not respond when the NE attempts to contact it, or if another call arrives for a server before the Retry delay has expired since a previous failure to contact the server. Values:
|
Retry delay | Change Inactive | The time in seconds that the NE should wait after a failure to contact the server before another call for the same server results in a new attempt to contact the server. If another call arrives for the same server during this time, the NE does not attempt to contact the server, but uses the Action on failure parameter to determine how to handle the call. Range: 0 - 3600 seconds (0 - 1 hour). A value of zero (the default) indicates that the NE always attempts to contact the server for every call, regardless of any previous failures. |
Originating server - billing of transfers | Change | Specifies what billing records should be created for a call when an originating server transfers an outgoing call to a new directory number. If the application server answers the call before forwarding it, the billing record starts from when the call is answered by the server; otherwise the call is billed from when the recipient answers it. Values:
|
Terminating server - billing of transfers | Change | Specifies what billing records should be created for a call when a terminating server transfers an incoming call to a new directory number. If the application server answers the call before forwarding it, the billing record starts from when the call is answered by the server; otherwise the call is billed from when the recipient answers it. Values:
|
Maximum call appearances | Change Inactive | The maximum number of simultaneous call branches in which the server can participate. Choose Use default to use the default value of 1024, or specify a value. |
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
Alarm log correlator | Read only | Identifier of the log message that was generated when this object last entered Attention Required or Attend To Dependent alarm state. This field is reset when the Attention Required alarm events and the Attend To Dependent alarm events are reset to zero. |
Additional alarm log correlator | Read only | If available, the identifier of the log message for the original event that caused the last Attention Required or Attend To Dependent alarm state for this object. This field is reset when the Attention Required alarm events and the Attend To Dependent alarm events are reset to zero. |
Attention Required alarm events | Read only / Reset | Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required. |
Attend To Dependent alarm events | Read only / Reset | Number of times (since the alarm count was reset) that this object's alarm state has gone to Attend To Dependent. |
Alarm state changed timestamp | Read only | The time at which the Alarm state last changed. |
Diagnostics - logging - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace - enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - API trace - trace tag | Change | An optional text string inserted into API tracing and PD logging for this object. (This string can include accented / international characters as defined in ISO 8859-1.) If you want to filter on this tag in the craft interface, do not include spaces or any of the characters ^ \ $ * + ? | ( ) , . ' ' " [ ] { }. |
Diagnostics - API trace - trace remote number | Change | The remote directory number that should be API traced. Outgoing calls made to this number or incoming calls received from this number should be API traced. If a directory number is not specified, all calls to and from this server will be API traced. |
VQM call logging | Change | This field appears only if VQM call logging is enabled on the Call Agent (in the Call Logging object). Specifies whether Voice Quality Management (VQM) data, if available, should be recorded for calls to or from this Application Server. You can view this data using the Call Logs function in the NE craft interface, as described in the IS, CA and MG Craft Interface Guide. Choose Use default or specify a value:
|
Requested status | Read only | Specifies whether an administrator has attempted to enable the Application Server. Values:
|
Actual status | Read only | Specifies the current status of the Application Server. Values:
