Manage Voice Gateways

The collector discovers Cisco or Avaya voice gateways on your network when those devices route calls to your call servers. However, you can manually add voice gateways to the database in the following circumstances:

• Analog telephones in your system are connected to a Cisco VG-224 gateway. These devices can appear incorrectly in reports unless you add them as gateways.
• Your network includes gateways that are in different SNMP communities, or that support different versions of SNMP. You can associate a gateway definition with an SNMP profile that contains gateway-specific security parameters.
• You suspect that SNMP community information is incorrect. The procedure for adding a voice gateway lets you review the SNMP security parameters and verify that the collector can poll the device.
• You want to create custom groups of devices and Locations in CA Performance Center. Groups let you grant view access to UC Monitor data when you configure user accounts. Include voice gateways in user permission groups.

You cannot add gateway voice interfaces. UC Monitor automatically polls the gateways and discovers information about available voice interfaces.

You can change the properties of Cisco and Avaya voice gateways that the collector detects on your network. You can also change the properties of voice gateways that you add to the database. If you delete an active voice gateway, UC Monitor automatically discovers it again when calls are sent through that gateway.

Follow these steps:

1. Click Administration, Data Collection, Media Devices, Voice Gateways in the navigation bar. The Voice Gateway List opens.
2. Take the following steps to add a voice gateway or change voice gateway properties.
   1. Click New to add a voice gateway, or select the voice gateway that you want to change and click Edit. The Voice Gateway Properties page opens.
   2. Complete the following fields as necessary:
      • Name. A name for the voice gateway. Typically, the DNS host name, although you can enter any name. If you do not know the DNS host name, enter the IP address in the Address field and click DNS.
      • Address. The IP address of the device in dotted notation, such as 10.10.2.34. If you do not know the IP address, enter the server DNS host name in the Name field and click IP.
      • IP Domain. The IP domain that is associated with this device. The IP domain is created in CA Performance Center. This field is available only when UC Monitor is registered to a CA Performance Center instance where at least one IP domain is defined.
      • SNMP Profile:

        Select the SNMP profile to associate with this gateway. The SNMP profile contains security information, such as the SNMP community string, to let the collector query the MIB of this gateway device. The default SNMP profile is used unless you select a custom profile from the list. Unless you changed it, the default SNMP profile uses the "public" community string.
        Click Verify SNMP to instruct the collector to try to contact the gateway using the specified SNMP profile.

        By default, the collector that detected the voice gateway is used for the verification. We recommend using the default collector. If verification fails, select another collector from the "from Collector" list and try again.

        Note: If you are monitoring by IP domain, the IP domain with which the collector associates call data is appended to the collector host name.

      • Monitoring Status. Whether data from this device is included in reports. The following options are available:
        -- Enabled: Monitoring is enabled for calls that are routed by this gateway device.
        -- Disabled: Calls that are routed by this device are not monitored. Data from the calls is discarded.
        -- Enabled (Sending Only): Monitoring is enabled only for calls that are sent from the PSTN through this gateway to phones in monitored Locations.
      • Perform routine traceroutes for the baseline. When enabled, routine traceroutes run to this device every four hours to establish a baseline of data about common paths through the network. Routine traceroute testing is enabled for each new Cisco gateway device. Routine traceroute testing is disabled for Avaya voice gateways, which do not perform call setup. The option is automatically disabled when the monitoring status is Disabled.
      • Description. (Optional) A description to help identify this device, including its location, capabilities, or past performance.
      • Voice Interfaces. Click Edit to change the properties of voice interfaces for the gateway. Complete the following fields, and then click OK.
      • Name. The name for the gateway voice interface. By default, the interface name is based on information from the gateway and the naming convention employed by the trunking equipment. You can supply a more easily remembered name for this field.
      • Discovered Capacity. The maximum number of simultaneous calls that this interface can support, according to information discovered by the collector. The collector finds information about interface capacity using different methods for each type of gateway device or protocol. The discovered capacity is collected from the gateway MIB.

        Note: In many cases, the collector can retrieve capacity information from its initial polling of the gateway. However, the collector does not retrieve changes in capacity information. Enter any changed information in this field.

      • Override Channel Capacity. By default, this value is the same as the Discovered Capacity. You can change the discovered capacity for reasons that depend on your environment. For example, the device MIB can misreport the interface capacity. Or for capacity-planning purposes, you want to see usage statistics in UC Monitor reports that reflect a different call capacity for an interface.

        Tip: The Voice Interface reports use the channel capacity information to calculate interface usage as a percentage of capacity. These reports are less accurate when the device MIB incorrectly reports channel capacity.

   3. Click Save. The Voice Gateway List displays the new voice gateway.
   4. Click Save & Add Another to save these properties and add another voice gateway. The Voice Gateway List reflects the changes you made.
3. Take the following steps to delete a voice gateway.
   1. Select the voice gateway you want to delete, and click Delete. The Confirm Delete page opens.
   2. Click Delete. The gateway is removed from the UC Monitor database and is no longer used to identify calls or call data in reports.
