Clustering

Configuration

To configure multiple instances of Softdial Telephony Gateway™ (STG) as a single cluster:

In the config.xml file of every STG that will be part of a cluster, set the following tags:

  1. <clusterMode>true</clusterMode>
    <telephonyLayerID>STG_Cluster1</telephonyLayerID>


    Each STG within a cluster should have the same layer ID. This layer ID is the string value specified in the Softdial Campaign Manager™ Client to assign a campaign to a single STG or a cluster of STGs as shown in Fig. 1.

    A default CTI layer with ID of __singlecti is required for tenant provisioning. Make sure there is one CTI layer with this default ID in your configuration.
  2. <telephonyLayerIP>x.x.x.x</telephonyLayerIP>

    This tag should be set to the IP address (or the machine name) of the machine to enable successful bridging of the calls within a cluster. This tag is important because it allows various STG nodes in a single cluster to communicate with each other directly, e.g. when the agent is nailed up using one STG node but the respondent is connected via a different SCC.
